▎ 摘  要

NOVELTY - Flame retardant nano-carbon coating current collector comprises two flame-retardant nano-coated carbon layers (3), two metal conductive layers (2) located between the flame-retardant nano-coated carbon layers, and a current collector substrate (1) located between the metal conductive layers. USE - The current collector is useful for anode sheet of battery used in electric device (claimed). ADVANTAGE - The current collector: is capable of improving battery multiplying power and charging and discharging performance of the battery; can avoid the thermal runaway caused by the internal temperature rise of the battery caused by the short circuit and continuous discharge of the battery, thus improving the safety performance of the battery and has anti-flaming nano-carbon coating peeling force more than 5 N/m, the average continuous combustion time less than 2 seconds, the puncture strength ≥ 50 gf, the longitudinal tensile strength of ≥ 150 MPa, and the longitudinal elongation ≥ 1%, transverse stretching strength ≥150 MPa and transverse elongation ≥ 1%. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparing the flame retardant nano-carbon coating current collector. DESCRIPTION OF DRAWING(S) - The drawing shows a structure schematic diagram of the flame-retardant nano-carbon coated current collector for anode sheet of battery used in electric device. 1Current collector substrate 2Metal conductive layer 3Flame-retardant nano-coated carbon layer
