▎ 摘　　要

NOVELTY - Anode sheet comprises anode active material layer including carbon nanotube clusters, binders and anode active particles. The surface coverage of the anode active particles is 5-50%. The carbon nanotube cluster is composed of multiple carbon nanotube units arranged in bundles, and the diameter of the carbon nanotube cluster is greater than 0.2 μm. The average diameter D of the carbon nanotube clusters is ≥ 0.5 μm. USE - The anode is useful for secondary battery of electronic device, and in digital electronic product, energy storage, unmanned aerial vehicle, electric tool and electric vehicle. ADVANTAGE - The anode has improved ion conductivity and internal resistance of anode sheet, so as to improve the high rate charging and discharging performance of the battery. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are also included for: econdary battery, comprising cathode sheet, a separator, an electrolyte, and the anode sheet; and electronic device, comprising: the secondary battery.
