20130224600 | NEGATIVE ELECTRODE MATERIAL POWDER FOR LITHIUM ION SECONDARY BATTERY, NEGATIVE ELECTRODE FOR LITHIUM ION SECONDARY BATTERY AND NEGATIVE ELECTRODE FOR CAPACITOR, AND LITHIUM ION SECONDARY BATTERY AND CAPACITOR - In a lithium ion secondary battery using a negative electrode material powder including a lower silicon oxide powder as a negative electrode material, a charge electric potential at 0.45-1.0 V relative to a Li reference upon initial charging results in a lithium ion secondary battery having a large discharge capacity with excellent cycle characteristics, which can be durable in practical use. On this occasion, the charge electric potential being 0.45-1.0 V relative to the Li reference upon initial charging means that an electric potential plateau caused by the generation of Li-silicate is observed, and the Li-silicate is uniformly generated in the negative electrode material, and this results in excellent cycle characteristics. The negative electrode material powder can have an electrically conductive carbon film on the surface with a ratio of the carbon film to the surface of the powder to be 0.2-10 mass %. | 08-29-2013 |
