摘要： Disclosed is an electrolyte for a battery comprising: (a) an electrolyte salt; (b) an organic solvent; and (c) a functional electrolyte additive. An electrochemical device comprising the electrolyte is also disclosed. The additive used in the electrochemical device effectively controls the surface of a cathode active material, which otherwise causes side reactions with an electrolyte, due to the basic skeleton structure and polar side branches of the additive. Therefore, it is possible to improve the safety of a battery, while not adversely affecting the quality of a battery.

摘要： A separator includes a porous substrate having a plurality of pores; a porous coating layer formed on at least one surface of the porous substrate and made of a mixture of a plurality of inorganic particles and a binder polymer; and a dot pattern layer formed on a surface of the porous coating layer and having a plurality of dots made of polymer and arranged at predetermined intervals. The separator may control short-circuit between positive and negative electrodes though an electrochemical device is overheated. Also, a united force to an electrode is enhanced due to the polymer dot pattern layer, thereby preventing the electrode and the separator from being separated. Accordingly, inorganic particles of the porous coating layer formed on the porous substrate are not separated, thereby improving stability of an electrochemical device.
