Description

ABSTRACT:
Organic electrolyte solutions and lithium batteries using the same are provided. The organic electrolyte solutions use a silane compound that prevents crack formation caused by volumetric changes in the anode active material during battery charging/discharging. This improves charge/discharge characteristics, thereby also improving stability, reliability, and charge/discharge efficiency of the battery.
