摘要:
A battery electrolyte solution contains from 0.01 to 80% by weight of an aromatic phosphorus compound. The aromatic phosphorus compound provides increased thermal stability for the electrolyte, helping to reduce thermal degradation, thermal runaway reactions and the possibility of burning. The aromatic phosphorus compound has little adverse impact on the electrical properties of the battery, and in some cases actually improves battery performance.
