Abstract
The invention provides a lithium ion battery, including an anode, a cathode and an electrolytic solution including imide anion based lithium salt and LiPOF. The cathode includes a cathode active material particle and a carbon conductive additive forming an island-bridge structure on the surface of the cathode active material particle. The carbon conductive additive includes graphenes partially covered with the surface of the cathode active material particle to form an island structure, carbon blacks attached on the surface of the graphene and carbon nanotubes connecting between graphenes as a bridge structure.
