Disclosed is an electrode, comprising a coating layer of crosslinked polymer, formed on a surface of electrode active material particles, while maintaining a pore structure formed among the electrode active material particles interconnected to each other in the electrode. A method for manufacturing the electrode and an electrochemical device comprising the electrode are also disclosed. The electrode, which comprises a coating layer of crosslinked polymer formed on the surface of the electrode active material particles, can improve the safety of a battery, while minimizing degradation in the quality of a battery.

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:
Disclosed is a porous film comprising: (a) a porous substrate having pores; and (b) a coating layer formed on at least one region selected from the group consisting of a surface of the substrate and a part of the pores present in the substrate, wherein the coating layer comprises styrene-butadiene rubber. An electrochemical device using the porous film as a separator is also disclosed. The porous film is coated with a styrene-butadiene polymer, whose rubbery characteristics can be controlled, and thus provides improved scratch resistance and adhesion to other substrates. When the porous film is used as a separator for an electrochemical device, it is possible to improve the safety of the electrochemical device and to prevent degradation in the quality of the electrochemical device.
