摘要： A battery which is high in battery voltage and can increase an energy density at charging. An anode (12) and a cathode (14) are laminated via an electrolyte−impregnated separator (15). The anode (12) contains a lithium composite oxide having at least one of cobalt and nickel and oxygen contained in an anode active matter. A charging battery voltage is at least 4.25 V. A total amount of lithium carbonate and lithium sulfate in the anode (12) is up to 1.0 mass% against an anode active matter, or the concentration of a proton impurity in an electrolyte is up to 20 ppm in terms of proton at a mass ratio against an electrolyte, or a water content in an electrolyte is up to 20 ppm at a mass ratio against an electrolyte. Accordingly, the elution of metals from a lithium composite oxide is restricted even at a high voltage.

摘要： A battery which can improve the chemical stability of an electrolyte and characteristics, and is provided with a rolled electrode element (20) comprising belt-like anode (21) and cathode (22) rolled via a separator (23). Lithium metal is deposited on the cathode (22) in the middle of charging, and the capacity of the cathode (22) is expressed by a sum of a capacity component by lithium occlusion/desorption and a capacity component by lithium metal deposition/dissolution. The separator (23) is impregnated with an electrolyte containing an electrolyte salt, which in turn contains a first lithium salt LiN (CnF2n+1SO2) (CmF2m+1SO2) and a second lithium salt such as LiPF6. Accordingly, the chemical stability of an electrolyte is improved, a side-reaction is restricted, and charge/discharge cycle characteristics are improved.
