Lithium-ion secondary battery and manufacturing method thereof |
摘要 |
In a lithium-ion secondary battery of the present invention, the electrical resistivity of the mixture of a positive electrode active material, an electrically conductive member, and a binder is 0.1 Omegacm or more but 1 Omegacm or less. The positive and negative electrodes each have an electrical capacity of 10 mAh or more but 50 mAh or less per volume of a rectangular parallelepiped that has a 1 cm2 square base on a face of the electrode of one polarity facing the electrode of the other polarity and that has a height equal to the thickness of the electrode of the one polarity at the square base. Used as the negative electrode thereof is a negative electrode formed by sintering graphite powder, non-graphitizing carbon, and fibrous powder retained in the pores of a porous metal structure in an inert gas atmosphere at a temperature of between 600 and 1000° C.
