More Information
Summary:A negative electrode for use in a secondary battery which comprises milled graphite fibers derived from mesophase pitch each having circumferential, upper end and lower end faces, said milled graphite fibers each being composed of graphite layers having therebetween voids as inlets and outlets for lithium ions, all of said circumferential, upper end and lower end faces having openings of said voids between the graphite layers, which serve as inlets or outlets for lithium ions. This negative electrode for use in a secondary battery can be utilized to provide a lithium secondary battery of nonaqueous electrolyte which has large charge and discharge capacities and which permits setting the current density at charge or discharge high.
