Electrolyte for lithium-ion battery and lithium-ion battery having the same

The invention improves the interfacial stability of the electrode material, ensuring the chemical and electrochemical stability of the electrolyte, and prevent the deterioration of the electrode material, and lithium ion which prevents the internal pressure increased due to gas generation by improving stability secondary battery electrolyte and this provide a lithium ion secondary battery that has, and a lithium ion secondary battery, the electrolyte is decomposed and an electrolyte of silyl sulfonate-based materials for collecting and forming a film on the anionic surface of the electrode.
