Abstract:
A graphite negative material for a lithium-ion battery includes a number of graphite layers parallel to each other. A number of channels are through the graphite layers. And the channels are capable of allowing lithium ions to pass therethrough freely. A method for preparing the graphite negative material and a lithium-ion battery including the graphite negative material are also provided.
