Lithium composite electrolyte FeS{sub 2} bipolar battery
- Tel Aviv Univ. (Israel). School of Chemistry
The goals are to develop and characterize a small laboratory prototype of a new lithium battery for electric vehicles (EV) and load leveling. This rechargeable battery consists of thin foils of: lithium anode, composite solid electrolyte (CSE) or composite polymer electrolyte (CPE) and a composite FeS{sub 2} (pyrite) cathode. Their battery has several advantages over other state of the art polymer electrolyte batteries: (1) The authors use a low cost cathode, pyrite is a natural ore, therefore it is environmentally friendly (2) Small prototype cells exhibited very high specific energy, projected to be 120 Wh/kg at C/5 to C/10 rate (three times larger than that of lead acid battery) and more than forty 100% charge-discharge cycles (3) their battery has an internal electrochemical overcharge protection mechanism (which is essential for EV batteries) (4) It was found that for both CSE and CPE the Li/electrolyte interfacial resistance is low and stable for up to 3,000h (CPE) and 700h CSE at 120 C. The long term projected specific energy for their battery is over 200 Wh/kg, five times larger than that of the lead acid battery and one of the highest among all batteries under development.
