| Zusammenfassung: | Electrolyte compositions containing a solvent, a co-solvent, certain cyclic carboxylic acid anhydride additives, certain phosphorus-containing additives, and an electrolyte salt are described. The electrolyte compositions are useful in electrochemical cells, such as lithium ion batteries where they provide significantly improved cycle life with no loss of discharge capacity. |
