▎ 摘 要
NOVELTY - The battery (100) has a solid electrolyte layer (106) arranged between a cathode electrode (102) and an anode electrode (104), where the anode electrode comprises a current collector (114) that comprises a graphene layer. The current collector comprises a carbon nanotube layer stacked with the graphene layer. The carbon nanotube layer comprises a set of carbon nanotubes joined with each other. The current collector comprises a strip shaped conducting tab connected to the carbon nanotube layer through a point contact. The graphene layer consists of a set of graphenes stacked with each other. USE - Thin film lithium ion battery. ADVANTAGE - The battery has high power density and prolonged service life. The battery allows a portion of a drawn carbon nanotube film not contacted with supporters to be suspended between the supporters if the drawn carbon nanotube film is placed between the separate supporters so as to maintain film structural integrity. DETAILED DESCRIPTION - The anode current collector is selected from a group consisting of graphene layer, carbon nanotube layer and metallic film. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic side view of a thin film lithium ion battery.
