Abstract
Organic electrolyte solutions and lithium batteries employing the same are provided. In one embodiment, an organic electrolyte solution includes a silane compound. The inventive organic electrolyte solutions prevent crack formation caused by volumetric changes in the anode active material during charging/discharging of the battery. This improves charge/discharge characteristics, resulting in improved battery stability, reliability, and charge/discharge efficiency, which is a dramatic improvement over conventional organic electrolyte solutions, which have higher irreversible capacities due to the decomposition of polar solvents.
