Abstract
The present invention is based on an electrode binding material including polyacrylics and a functional group substituent(Li, Na, K) as a binder of an electrode. The present invention provides a polyacrylic acid an electrode binding material including a polyacrylics mixture having a high degree of polymerization and a functional group with Li, Na or K being substituted and high efficiency Lithium secondary battery utilizing a silicon anode active material etc. using the same. Therefore, the electrode binding material of the present invention has an excellent binding force, and can reduce side reactions in reactions of a secondary battery, and maintain a stable cycle property, and also enhance electric performance.
