Ni-Co Alkaline rechargeable batteries.
Nickel-Cobalt Battery LLC has developed robust nickel-cobalt (Ni-Co) battery prototypes that come close to Li-ion batteries in electrical parameters. In regards to safety, performance, and environmental impact, they are superior to most existing battery types. Ni-Co batteries can be an excellent alternative for Li-ion batteries for hybrid cars, electric vehicles, consumer and UPS applications, and airplanes.
The positive electrode is a nickel oxide with chemical composition similar to that used in batteries Ni-Cd, Ni-MH. The difference, however, is that no additives or binders are utilized. There is only a nanoporous nickel frame on the surface of which a layer of electrochemically formed nickel hydroxide active mass is grown, with the specific capacity 0.305 Ah/g.
A negative electrode is based on cobalt hydroxide. It is also formed by proprietary electrochemical building of active mass on nickel,titanium or iron foil, specific capacity - 0.66 Ah/g'

Cobalt electrode
Characteristics:
- Maximum specific power: 4.5 kW / kg., Single cell voltage : 1.24V
- Energy density: 342 Wh/l (estimation in improved models - 550Wh/l).
- Specific energy: 192 Wh/kg (based on the dry weight of active mass).
- Specific energy: 120 Wh/kg (with battery housing, including substrates, separator with electrolyte, conducting materials). This data is based on a small prototype and can be enhanced further by improving the battery housing, increasing the thickness of the positive electrode active layer, and a bipolar battery design.
- Fast charging: EV-size battery can be fully charged in 30 minutes to 100% capacity without special charger.
- Functional in any orientation in working mode.
- No fire, explosion, or ignition hazards.
- Operational in both high and low temperatures.
- Low cost of production: $0.17 per 1 Wh.
- Life reduced with deep cycle use - none.
- Ease of recycling of waste batteries: electrodes are regenerated in the production line of manufacturing of electrodes, without intermediate conversion, thus reducing the price of the replacement battery by 50%.
- Simplicity of design and production process.
- Robust battery without protection/control overhead.
- No memory effect problem.
- Self-discharge does not lead to battery degradation, and after charging, the Ni-Co battery returns to its full capacity.
- Promising results obtained on minimization of self discharge during extended shelf life.
