✦ Synopsis

An Li/LixMnO2 rechargeable system was developed. The AA cell based on a lithium metal anode and lithiated manganese dioxide cathode, organic electrolyte and polypropylene separator, exhibits excellent performance and safety behaviour. The cell possesses an energy density of 125 to 140 Wh/kg and 280 to 315 Wh/l. An accumulated capacity of about 200 Ah can be achieved under cycling. The system incorporates a chemical mechanism preventing explosion, fire and venting with fire under abuse conditions such as short circuit, overcharge, deep discharge, etc.
