Abstract To perform an excellent secondary battery performance for a negative electrode comprising an anode activator containing a silicon-based material and a graphite, and a conductive agent.SOLUTION: A secondary battery is formed by including an anode activator (a silicon-based material and graphite), a conductive agent, a negative electrode with a binder, and a fluoroethylene carbonate as an electrolyte, and the negative electrode is achieved by adopting a polyvinyl pyrrolidone (PVP) or a negative electrode additive agent consisting of the polyvinyl pyrrolidone as a main component.SELECTED DRAWING: None 【課題】ケイ素系物質と黒鉛を含む負極活物質と、導電剤とを備えた負極に対して優れた二次電池性能を発揮させることである。【解決手段】負極活物質（ケイ素系物質と黒鉛）と、導電剤と、バインダーを備えた負極と、前記電解質としてフルオロエチレンカーボネートを含んでなる二次電池において、前記負極がポリビニルピロリドン（ＰＶＰ）又は主成分としてポリビニルピロリドンを含んでなる負極用添加剤を採用することにより達成される。【選択図】なし
