During the second year of research under NASA SBIR Contract NAS7-967, Covalent Associates and NASA contract monitors at the Jet Propulsion Laboratory agreed to perform an evaluation of the three best electrolytes developed during Phase 2. Due to the extensive period of time required to collect meaningful cycling data, we realized the study would extend well beyond the original formal end of the Phase 2 program (August 31, 1988). The substitution of this effort in lieu of an earlier proposed 20-cell final deliverable is formally documented in Modification No. 1 of Contract NAS7-967 as task 7. This Addendum contains the results of the cycling studies performed at Covalent Associates. In addition, sealed ampoules of each of these three electrolytes were delivered to the Jet Propulsion Laboratory Electrochemical Power Group. Their concurrent evaluation in a different test vehicle has also been recently concluded and their results are also summarized herein.

Cycle life and safety of delta-LiAl/TiS2 cells were evaluated using laboratory and AA-size cells. Analysis of the alloys (which contained 60, 70, 80, or 85 wt-pct. lithium and are designated 60 LiAl etc.) showed them to contain a mixture of elemental Li and Al4Li9. Cycling efficiencies correlated with the amount of free lithium in the anode. Using an electrolyte with the composition 48 v/o THF:48 v/o 2-MeTHF:4 v/o 2-MeF/LiAsF6(1.5M), a 70 LiAl/TiS2 laboratory cell yielded a cycling efficiency of 96.4 pct. when cycled at a 100 pct. discharge depth which compares well with Li anode cycling efficiencies of 96 to 97.5 pct. obtained previously in this electrolyte. The highest cycling efficiency of any delta-LiAl/TiS2 laboratory cell was 96.7 pct. when the 60 LiAl alloy was used with the 35 v/o PC:35 v/o EC:30 v/o triglyme/LiAsF6(1.0M) electrolyte. The 70 LiAl alloy was selected for further testing in AA cells since it was malleable for the fabrication of spirally wound electrodes, and its overall cycling performance was sufficiently good. AA-size 70 LiAl/TiS2 cells appear to have capacity/rate properties similar to those for identical Li/TiS2 cells. The use of the delta-LiAl alloy anodes does not appear to offer any safety advantage when cycled cells are shorted or heated.

This viewgraph presentation discusses the Moltech Corporation's history and structure, power systems development, product attributes, Li-S adapted products, cell construction, specific energy comparisons, and product requirements necessary for use in spacecraft applications.

Several flexible, low-cost inorganic-organic separators with performance characteristics and cycle life equal to, or better than, the Lewis Research Center Astropower separator were developed. These new separators can be made on continuous-production equipment at about one-fourth the cost of the Astropower separator produced the same way. In test cells, these new separators demonstrate cycle life improvement, acceptable operating characteristics, and uniform current density. The various separator formulas, test cell construction, and data analysis are described.

The lithium molybdenum disulfide system as demonstrated in a C size cell, offers performance characteristics for applications where light weight and low volume are important. A gravimetric energy density of 90 watt hours per kilogram can be achieved in a C size cell package. The combination of charge retention capabilities, high energy density and a state of charge indicator in a rechargeable cell provides power package for a wide range of devices. The system overcomes the memory effect in Nicads where the full capacity of the battery cannot be utilized unless it was utilized on previous cycles. The development of cells with an advanced electrolyte formulation led to an improved rate capability especially at low temperatures and to a significantly improved life cycle.

I looked for smart charger chat can charge 9V NiMH battery in couple of hours and didn't found one. Moreover all chargers I found was really "dumb". Charging current unknown and no function to terminate charging after battery fully charged. Problem with such chargers that they can overcharge battery and significantly reduce lifespan. So I decided to create "smart" charger using Arduino. First version I intend to keep simple, so it allows basic things like charging with constant current, automatic charging termination after battery fully charged, trickle charge, measurement of charge transferred to battery. In next version I will add couple of additional useful features like discharge, capacity measurement and cycling. All sketches inside charger.zip schematic.pdf - schematic of circuit not including LCD connection Warning: Charging battery with high current may cause battery explosion or fire. Please don't leave charger unattended. Also please don't try to charge battery don't intended to be charged as Alkaline. This charger tested only with NiMH batteries (and still you are using it at your own risk and I am absolutely have no any responsibility if any damage caused because of bugs in desigh or code). Chagrin of other types of batteries will require code modification.

Just a simple container for rechargeable AA batteries. One for the dead ones, one for the charged ones.

Since the implementation of distributed operations with a higher density of tactical field radios, optics and electrical tactical equipment, the demand for batteries has increased significantly. While advances in technology have increased the lethality of Defense (DoD) forces, sustainment and increased resupply convoys have increased the risk of logistical support and costs. This thesis examines the viability, cost savings, and operational weight associated with the use of rechargeable batteries.

Lithium-ion batteries, a popular electric energy storage device, have high energy density and impressive working performance. However, the temperature affects its life cycle, capacity, and performance. Different effects are generated inside the battery for the different temperature conditions. It is necessary to study their thermal and electric characteristics in various thermal conditions since electric energy storage devices are used in various applications at low or high temperatures. In this study, the experimental analysis was performed to observe how a battery cell behaves above room temperature for a different 18650 cylindrical battery cell with a capacity of 5200 mAh. The testing temperature for this experiment was at 28˚C, 50˚C, 60˚C, 70˚C, and 100˚C. It is noted that the capacity of the battery cell fades drastically at high temperatures compared to low temperatures due to internal short circuits occurring at high temperatures.

Crystal chemical principles and transport theory have been used to predict structures and specific compounds which might find application as solid electrolytes in rechargeable high energy and high power density batteries operating at temperatures less than 200 C. Structures with 1-, 2-, and 3-dimensional channels were synthesized and screened by nuclear magnetic resonance, dielectric loss, and conductivity. There is significant conductivity at room temperature in some of the materials but none attain a level that is comparable to beta-alumina. Microwave and fast pulse methods were developed to measure conductivity in powders and in small crystals.

I have a lot of batteries, especially rechargeable batteries with various powers. I needed a storage in which I could have: - batteries recharged long ago come out first, - batteries of a similar form factor but different capacities sorted in different places. So I came up with this case, adaptable for AA, AAA and 18650 batteries, actually any cylinder-formed batteries. It comes in 2 parts: the case itself, and an extra piece that prevents other batteries from coming out when taking the bottom battery. You simply organize them from right to left as weaker to stronger (or the opposite if you prefer that!), and you add new batteries on top of others. Then you easily pick them from the bottom with one or two fingers, the others will simply fall in place. This is also fully customizable in the scad file: choose your battery size, the number of columns and number of batteries per column.

Nano sized LiNi0.5-2xRuxMn1.5O4 (x=0, 0.01, 0.03 and 0.05) spinels have been successfully synthesized by polymer assisted method. SEM observation shows that particles' sizes of LiNi0.5-2xRuxMn1.5O4 are around 300 nm. XRD and FTIR measurements prove that all Ru doped samples have phase pure spinel structure with Fd3m space group, while pristine LiNi0.5Mn1.5O4 contains impurity phase (LixNi1-xO). The nano sized LiNi0.5Mn1.5O4 can release 117 mAh. g-1 at 10 C discharge rate; while, the nano sized LiNi0.4Ru0.05Mn1.5O4 can deliver 135 mAh. g-1 at 10 C discharge rate. In 500 cycles 10 C charge/discharge test, the nano sized LiNi0.4Ru0.05Mn1.5O4 can initially deliver near 121 mAh. g-1 and still keep 100 mAh. g-1 at the 500th cycle exhibiting much better cyclic performance than the pristine LiNi0.5Mn1.5O4. It also exhibits excellent cyclic performances when charge/discharged at 10C for 1000 cycles. The great improvements on high rate performances of Ru doped cathodes can be attributed to their higher electronic conductivity and lithium diffusion coefficient, which are achieved through both Ru doping and reduction of particle size.

Report developed under SBIR contract covers the syntheses and electrochemical characterizations of novel polymer electrolytes derived from compounds synthesized via enzyme-catalyzed polymerization(ECP) techniques. A reproducible method was developed to functionalize target monomers via the Mitsunobu reagent, and subsequently polymerizing the modified monomers utilizing enzyme catalytic method. Specifically, polyphenols were reacted with three main types of alcohols in order to establish trends for the incorporation of enhanced ionic conductivity in these materials. The materials synthesized were found to be complex mixtures of derivatized polyphenols which we sought plus coupled polyphenols and coupled alcohols. This molecular complexity maybe beneficial in ensuring that the materials remain amorphous over a broad temperature range. This is an important feature of solid-state polymer electrolyte for battery applications. Functionalization of a biphenol, with subsequent enzyme-catalyzed polymerization, was also attempted and this effort was successful in obtaining samples for polymer film processing and later electrochemical characterizations. Conductivities of polyphenol-derived polymers were found to be superior to pure PEO, and the materials were found to be electrochemically stable up to 5.0 volt versus Li. The use of inert additives such as TiO2 and SiO2 should further enhance the conductivity of the polyphenol-derived polymer electrolyte films.

New rechargeable battery technology is described and compared with classical primary battery back-up of SRAM PC cards. Thin solid polymer electrolyte cells with the thickness of TSOP memory components (1 mm nominal, 1.1 mm max) and capacities of 14 mAh/sq cm can replace coin cells. The SRAM PC cards with permanently installed rechargeable cells and optional electrochromic low battery voltage indicators will free the periodic PC card user from having to 'feed' their PC cards with coin cells and will allow a quick visual check of stored cards for their battery voltage status.

The use of aromatic radical ions is proposed as anode material for high energy density, ambient-temperature, secondary batteries. Preliminary data are promising, showing that the naphthalenide anion can provide high current-densities at practical current-collectors like steel and nickel. However, the present test-electrode design did not confine naphthalene long enough to demonstrate rechargeability over a number of cycles. Two approaches are recommended to containing the aromatics close to a current-collector for extended periods of charge-discharge cycling. (Author )

So you need a D cell or two. This will use 3 AA's in parallel so the power output should be close to a D cell. I use 1 button brass fastener on top with tin foil folded to connect all 3 AA's. And 3 button brass fasteners on the bottom without tin foil because the 3 fasteners are bent to connect all 3 AA's. There are 3 fasteners on the bottom to make sure the bottom will connect with all types of springs. Notice the extra bend in the fasteners on the bottom that would go out the side of this thing. By bending inward, the battery bottom connects easier to this adapter. The slot for each AA is 15mm wide so a rechargeable can fit as well as normal alkaline batteries.

This article is from Chemistry (Weinheim an Der Bergstrasse, Germany) , volume 18 . Abstract Abstract: The decomposition reaction of niobium(V) oxytrichloride ammoniate to the oxynitride of niobium in the 5+ oxidation state was developed in a methodological way. By combining elemental analysis, Rietveld refinements of X-ray and neutron diffraction data, SEM and TEM, the sample compound was identified as approximately 5 nm-diameter particles of NbO1.3(1)N0.7(1) crystallizing with baddeleyite-type structure. The thermal stability of this compound was studied in detail by thermogravimetric/differential thermal analysis and temperature-dependent X-ray diffraction. Moreover, the electrochemical uptake and release by the galvanostatic cycling method of pure and carbon-coated NbO1.3(1)N0.7(1) versus lithium was investigated as an example of an Li-free transition-metal oxynitride. The results showed that reversible capacities as high as 250 and 80 A h kg−1 can be reached in voltage ranges of 0.05–3 and 1–3 V, respectively. Furthermore, a plausible mechanism for the charge–discharge reaction is proposed.

This report details the work performed on Phase I of an overall two- phase program. The aim of Phase I is to select a room-temperature lithium (Li) rechargeable couple that offers high energy density (60-90 Wh/1b), good rate capability (C/6-C/1), and low temperature operability. Among the four cathode systems investigated - V205, Tis2, v2s5 and LixCo02 - the Li/V2O5 couple emerged as the best performer capable of meeting the performance goals described above. The other three cathode systems were dropped from further development during the course of the program because of their general instability with ester-based electrolytes, especially the methyl formate (MF)-based electrolyte. The MF-based electrolyte was selected because of its superior conductivity which is essential for rate capability and low temperature operability.

"This paper covers the use of cellulose paper simultaneously as electrolyte, separation of terminals, and physical help of a battery controlled battery. The testimony on the two substances of a paper sheet of metal or metal oxides dainty layers with different electrochemical potential outcomes, independently as anode and cathode, such as Cu and Al, lead to a yield voltage of 0.70 V and a stream thickness that varies between 150 n A cm and 0.5 m A cm, subject to the paper structure, thickness and the dimension of OH species adsorbed in the paper matrix. The electrical yield of the paper battery is self governing of the terminals thickness yet strongly depends on the climatic relative stickiness RH , with a stream thickness redesign by various solicitations of significance when RH changes from 60 to 85 . Other than versatility, negligible exertion, low material use, regular very much arranged, the power yield of paper batteries can be changed in accordance with the perfect voltage– current required, by genuine mix.

Titanium has become available as a commercial metal only since World War II, and, at low price, a decade later. This explains the fact that Ti has not been utilized as a reactant or energy-supplying material in batteries, despite its advantageous properties -- its low weight-density and the high energy-density of its reaction with oxygen and halogens. After a review of the occurrence and technology of titanium, the history of its studies in the USA and in the U.S.S.R., its electrochemical behaviour in aqueous and nonaqueous and molten salt media is discussed. Suggestions on the choice of materials for anodes, cathodes and electrolytes for Ti batteries are presented and several electrochemical reactions on which these batteries are based are offered.

This is not the way we want to be on fire. We’re averaging two battery-related fires like this one EVERY WEEK at our landfills and recycling centers. It’s caused by rechargeable batteries tossed where they don’t belong. That’s dangerous for your home, for the drivers picking it up and for our staff at the centers. You’ll find rechargeable batteries in things like: - Power tools - Vapes - Electronics (phones, tablets, laptops) - E-scooters So where should rechargeable batteries go? Bring them to our full-service centers and we’ll safely dispose of them for FREE. Single-use batteries like AA and AAA can go in the trash: WipeOutWaste.MeckNC.gov/Batteries Not sure what kind of battery you’ve got? Bring it anyway. We’ll handle it.

During the past ten years research on lithium batteries increasingly directed towards a rechargeable battery system as many primary lithium batteries are now commercially available. Most of the research on the secondary lithium batteries has been on systems with solid insertion cathodes and nonaqueous, liquid organic electrolytes with a wide variety of solvents and compounds having been evaluated. Recent studies on polymer electrolyte systems have resulted in solid state rechargeable lithium cells, operable at 25 C. Capacity decline with cycling and the high internal resistance at low temperatures limit the application of these systems. Continuous work in this area will improve the performance characteristics of these cell systems.

LithChem Energy (LCE) successfully designed and built a partially automated lithium-ion bi-cell production machine to produce lower cost prismatic lithium-ion batteries for the DOD. This machine was completed and started up to produce a short run of lithium-ion bi-cells with lithium cobaltate as the cathode material. This system included the design and successful fabrication of two dip coaters, a brush tabber for the coated electrodes to form the weldable electrodes, and a coater for priming the electrode metal grids prior to dip coating. Work stations were constructed for quantitative cell filling, resistance welding of the cell pack electrodes, and for cell pack formation. The prismatic cell packs were designed to be 6 Ah with eight of these to fit into the space of a BB2590 to achieve 12 V and 24 V circuits. In a parallel effort, a new high energy capacity cathode material was optimized based on a lithium nickel cobaltate which achieved an energy density of 230 mAh/g in the voltage range of 2.6 V to 3.9 V at C/10. This cathode material also exhibited high power density up to 40 C discharge rates. This advanced manufacturing System and new cathode material have been designed to lower the cost of All-American made rechargeable lithium-ion cells and batteries for the DOD.

Advances in the past decade of the energy and power densities of lithium-ion based batteries for hybrid electric vehicles and various consumer applications have been substantial. Rechargeable high rate lithium-ion batteries are now exceeding 6 kW/kg for short discharge times 15 seconds). Rechargeable lithium-ion polymer batteries, for applications such as remote-control aircraft, are achieving simultaneously high energy density and high power density (160 Whr/kg at 1.0 kW/kg). Some preliminary test data on a rechargeable lithium-ion polymer battery is presented. The use of high rate rechargeable lithium-ion batteries as a function of onboard power, electric laser power level, laser duty cycle, and total mission time is presented. A number of thermal management system configurations were examined to determine system level weight impacts. Lightweight configurations would need a regenerative thermal energy storage subsystem.
