▎ 摘 要
NOVELTY - A battery has an electrode (e1) comprising particles containing lithium, a layer of carbon which is least partially coated to a surface of portion(s) of particles and electrochemically exfoliated graphene which is least partially coated to portion(s) of particles, an electrode (e2) and an electrolyte. At least one portion of electrode (e1) and at least one portion of electrode (e2) contact electrolyte. USE - Battery e.g. lithium-ion battery for electric car. ADVANTAGE - The battery has excellent durability and cycling characteristics. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for the following: (1) electrode material; and (2) manufacture of electrode material. DESCRIPTION OF DRAWING(S) - The drawing shows the schematic view of the particles of lithium-iron phosphate-electrochemical graphene.
