LITHIUM SECONDARY BATTERY CONTAINING CAPSULE FOR CONTROLLED-RELEASE OF ADDITIVES

摘要

Provided is a lithium secondary battery comprising a controlled-release capsule which continuously releases a desired amount of additives necessary for electrolytes or electrodes at a constant level and is included in an electrolyte and/or an electrode material, thereby providing inherent effects of additives while simultaneously minimizing adverse side reactions of surplus additives, consequently optimizing the battery performance.
