Abstract: A lithium nonaqueous secondary battery is described which contains certain dopants to improve the recycling characteristics of the battery. Also, certain of these dopants act as wetting agents for the polypropylene separator. These batteries exhibit increased cycle life and increased cycle efficiency. Also, these batteries are more easily manufactured since vacuum filling to wet the separator is not necessary. These dopants include polyalkylene glycol ethers, tetraalkyl ammonium halides, and certain lithium salts.

Abstract: A particular class of transition-metal chalcogenides which have a fibrous structure are found to exhibit particularly desirable secondary battery characteristics. Fibrous structure is retained on discharge and charge which contributes to the maintenance of large energy densities after extensive recycling.
