Abstract:
A lithium-ion secondary battery allowed to improve cycle characteristics and initial charge-discharge characteristics is provided. The lithium-ion secondary battery includes a cathode; an anode; and an electrolytic solution. The anode includes an anode active material layer including a plurality of anode active material particles. The anode active material particles each include a core section and a coating section applied to a part or a whole of a surface of the core section, and the core section includes a silicon-based material (SiOx: 0≦x
