摘要:
To provide high energy density, good cycle properties and rate characteristics and long-term safety of a lithium ion battery containing at least an ionic liquid and a lithium salt. The above problems are solved by suppressing reduction and decomposition of the ionic liquid on an anode by using a graphite coated with an amorphous carbon or onto which an amorphous carbon is deposited as an anode active material.
