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.
