摘要 |
The loss in delivered capacity (fade) after cycling non-aqueous rechargeable lithium batteries can be reduced by incorporating a small amount of certain additive compounds in the battery. The additive compound comprises boron, oxygen, and organic end groups that are chemically compatible with the battery components. The structure of the additive compound contains a boroxine (BO)3 ring. The invention is particularly suited to lithium ion batteries. Trimethoxyboroxine and trimethylboroxin are particularly effective additives. Preferably, the additive compound is dissolved in the electrolyte. <IMAGE> |
