Title:
二次電池用電解液
Document Type and Number:
Japanese Patent JP4947873
Kind Code:
B2
Abstract:
A reversible lithium ion cell has a graphitic material as the anode material, and the electrolyte includes propylene carbonate and also a chlorinated diethyl carbonate, and a lithium salt, the concentration by weight of the chlorinated diethyl carbonate being less than 2%. The chlorinated diethyl carbonate appears to form a passivating layer on the surface of the graphite that prevents interaction of propylene carbonate with graphite, but does not impede reversible intercalation of lithium ions. Such cells may be used over a wide temperature range, and have good capacity.
