MIXTURE FOR ANODE OF IMPROVED ADHESIVE STRENGTH AND LITHIUM SECONDARY BATTERY CONTAINING THE SAME |
摘要 |
Provided is an anode mix for a secondary battery comprising an anode active material, a conductive material and a binder, wherein the anode mix contains 0.01 to 1.0% by weight of alumina having an average particle diameter of less than 1000 nm, based on the total weight of the mix, and a lithium secondary battery comprising the same. Therefore, the present invention can achieve increases in anode active material-conductive material adhesion and anode active material-current collector adhesion which are exerted by a binder, and ultimately can improve lifespan characteristics or cycle characteristics of the battery. |
