    摘要： Disclosed is a non-aqueous electrolyte secondary battery having an excellent preservation characteristic at a high temperature and charging/discharging cycle characteristic.A rolled body in which a strip-shape positive electrode and negative electrode are rolled with a separator in-between is provided inside a battery can. The positive electrode contains LixMn2−yMayO4 (where, Ma is at least one element selected from the group consisting of metal elements other than Mn, and B) and LiNi1−zMbzO2 (where, Mb is at least one element selected from the group consisting of metal elements other than Ni, and B). By replacing part of Mn and Ni with other elements, the crystal structure can be stabilized. Thereby, the capacity retention ratio after preservation at a high temperature, and a heavy load discharging power under a high electric potential cutoff can be improved. The mean particle size of particles of the above-mentioned oxides are preferable to be 30 μm and below so that an excellent charging/discharging cycle characteristic can be obtained.

    摘要： The present invention provides a non-aqueous electrolyte secondary cell including: a lithium-nickel composite oxide as a cathode active material and a material having a specific surface in the range from 0.05 m2/g to 2 m2/g as an anode active material. When A is assumed to be the weight of the lithium-nickel composite oxide and B is assumed to be the weight of the cathode active material other than the lithium-nickel composite oxide, the mixture ratio R expressed A/(A+B) is in the range from 0.2 to 1. This combination of the cathode active material and the anode active material enables to obtain an improved anti-over discharge characteristic even when an anode current collector contains Cu.

    摘要： Provided is a battery with a higher capacity and superior charge-discharge cycle characteristics. A cathode contained in a package can and an anode contained in a package cup are laminated with a separator in between. The separator is impregnated with an electrolyte solution formed by dissolving lithium salt in a solvent. The anode comprises a tin-containing material including metallic tin and an intermetallic compound including tin in the same particle. A higher capacity and superior charge-discharge cycles can be obtained by the tin-containing material.
