Recently an all inorganic ambient, low pressure lithium non-aqueous rechargeable battery system was discovered by duracell. This system can have energy densities higher than 1000 whr/kg, and also can discharge/charge at high current rate. It is the objective of this project to come out with mixed inorganic-organic solvents/electro- lytes to make this battery system function efficiently over a wide range of temperature, nd applications. Unique property of this battery system would allow to use different cathodes to tailor-make batteries for many uses. The latter is possible with a good solvent and electrolyte.
