Verwendung von B203 als Additiv in nichtwässigen Elektrolyten von wiederaufladbaren Lithiumbatterien

摘要

The loss in delivered capacity upon cycling nonaqueous rechargeable lithium batteries can be reduced by incorporating a small amount of B2O3 additive in the electrolyte. The B2O3 additive is preferably dissolved in the electrolyte prior to assembling the battery. The invention is particularly suited to lithium ion rechargeable batteries.
