Title:
A silicon oxide, a manufacturing method for the same, a cathode, a rechargeable lithium-ion battery, and an electrochemical capacitor
Document Type and Number:
Japanese Patent JP6156089
Kind Code:
B2
Abstract:
A silicon oxide material having a cobalt content of 2-200 ppm is provided. A negative electrode is formed using the silicon oxide material as active material. A nonaqueous electrolyte secondary battery constructed using the negative electrode exhibits improved cycle performance while maintaining the high battery capacity and low volume expansion of silicon oxide.
