ACTIVE MATERIAL FOR NONAQUEOUS ELECTROLYTE SECONDARY BATTERIES, METHOD FOR PRODUCING THE SAME, AND NEGATIVE ELECTRODE INCLUDING THE SAME |
摘要 |
The invention provides an active material for nonaqueous electrolyte secondary batteries which contains a silicon oxide as an active material and can suppress the generation of gas during storage at high temperatures, a method for producing such active materials, a negative electrode for nonaqueous electrolyte secondary batteries including the active material, and a nonaqueous electrolyte secondary battery including the negative electrode. An active material for nonaqueous electrolyte secondary batteries is used which includes a silicon oxide having a surface coated with a polyacrylonitrile or a modified product thereof that has been heat treated. |
