Abstract :
The PolyPlus Battery Company (PPBC) is developing an advanced lithium polymer rechargeable battery based on proprietary positive electrode chemistry. In one formulation, this electrode contains elemental sulfur, either free or in association with secondary materials that promote its utilization. Batteries based on this cathode chemistry offer high steady-state (>250 W/kg) and high peak power densities (3000 W/kg), in a low cost and environmentally benign format. High energy density, in excess of 500 Wh/kg (600 Wh/l) can also be achieved. The high power and energy densities, along with the low toxicity and low cost of materials used in the PolyPlus solid-state cells make this battery exceptionally attractive for both hybrid and electric vehicles, and for consumer electronic applications
