摘要： Provided is a secondary battery in which high energy density can be obtained and charging/discharging cycle characteristic can be improved. A positive electrode (13) and a negative electrode (15) are stacked with a separator (16) interposed therebetween, and are enclosed inside an exterior can (11) to which an electrolyte is injected. The negative electrode (15) contains a negative electrode material capable of occluding/releasing lithium in an ionic state. Thereby, lithium metal precipitates in the negative electrode (15) in a state where the open circuit voltage is lower than the overcharge voltage. In other words, lithium is occluded in an ionic state in a negative electrode material capable of occluding/releasing lithium in the beginning of charging, and then lithium metal precipitates on the surface of the negative electrode material thereafter during charging. The amount of precipitation of lithium metal is preferable to be from 0.05 to 3.0 times, both inclusive, the ability of charging capacity of the negative electrode material capable of occluding/releasing lithium. Thereby, a high energy density and an excellent cycle characteristic can be obtained.

摘要： Provided is a battery capable of improving chemical stability of an electrolyte and battery characteristics such as discharge capacity, charge-discharge cycle characteristics and so on. The battery comprises a spirally wound electrode body (20) including a strip-shaped cathode (21) and a strip-shaped anode (22) spirally wound with a separator (23) in between. During charge, lithium metal is precipitated on the anode (22), so the capacity of the anode (22) includes a capacity component by insertion and extraction of lithium and a capacity component by precipitation and dissolution of the lithium metal, and is represented by the sum of them. The separator (23) is impregnated with an electrolyte solution formed through dissolving a lithium salt in a solvent. Vinyl ethylene carbonate, divinyl ethylene carbonate or the like is added to the electrolyte solution, thereby the chemical stability can be improved.
