摘要:
Propylene sulfite (PS) has been studied as a film-forming electrolyte additive for use in lithium ion battery electrolytes. Even small amounts in the order of 5 vol.% PS suppress propylene carbonate (PC) co-intercalation into graphite. In addition, a 1 M LiClO4/PC/PS (95:5 by volume) electrolyte is characterised by a high oxidation stability at a LiMn2O4 cathode. (C) 1999 Elsevier Science S.A. All rights reserved.
