NON-AQUEOUS ELECTROLYTE SECONDARY BATTERY AND NON-AQUEOUS ELECTROLYTE |
摘要 |
To provide a non-aqueous electrolyte secondary battery which restrict reaction between a negative electrode active material and a non-aqueous electrolyte, and can attain excellent charge-discharge cycle performances and high charge-discharge capacity, where a thin filmof negative electrode activematerial including a metal capable of absorbing or releasing lithium is formed on a current collector of the non-aqueous electrolyte secondary battery, and the thin filmof negative electrode active material is separated into columnar shape by slits formed in a thickness direction. In the non-aqueous electrolyte secondary battery that comprises a negative electrode 2, in which a thin film of negative electrode active material 2a including a metal capable of absorbing or releasing lithium is formed on a current collector 2b and this thin film of negative electrode active material 2a is separated into columnar shape by slits 2c formed in a thickness direction, a positive electrode 1 containing a positive electrode active material capable of absorbing or releasing lithium, and a non-aqueous electrolyte prepared by dissolving lithium salt in a non-aqueous solvent, the non-aqueous electrolyte contains carbonate compound having alkyl group combined with fluorine. |
