Abstract
The present invention improves cell characteristics at a low temperature. The negative electrode contains fiber carbon, which enables smooth doping and dedoping of lithium ions at a low temperature. Accordingly, the internal resistance value at a low temperature is reduced and the cell capacity value is increased.
Claims9
