| 发明名称 | Negative electrode active material for electric device | ||
| 摘要 | A negative electrode active material for an electric device includes an alloy containing silicon in a range from 25% to 54% exclusive, carbon in a range from 1% to 47% exclusive, zinc in a range from 13% to 69% exclusive in terms of mass ratio, and inevitable impurities as a residue. For example, the negative electrode active material can be obtained with a multi DC magnetron sputtering apparatus by use of silicon, carbon and zinc as targets. An electric device using this negative electrode active material can improve the initial charge-discharge efficiency while keeping the cycle property. | ||
