▎ 摘  要

NOVELTY - Anode sheet comprises a conductive agent comprising a one-dimensional conductive material and a two-dimensional conductive material. The weight ratio of the conductive agent in the anode sheet, the weight ratio between the one-dimensional conductive material and the two-dimensional conductive material, the specific surface area of the one-dimensional conductive material and the secondary particle size distribution parameters of the two-dimensional conductive material satisfy the following relationship: 1.6 ≤ A * BET/D + C ≤ 6, where A represents the weight ratio, BET represents the specific surface area, D represents the secondary particle size distribution parameter, and C represents the weight ratio. USE - The anode sheet is useful for ion battery (claimed) used in electronic device, new energy automobile and aerospace field, and in lithium-ion battery. ADVANTAGE - The sheet: synergistically improves the low-temperature direct current (DC) internal resistance, low-temperature charging and low-temperature rate discharge performance of the ion battery; improves the low-temperature battery performance of the ion battery; is suitable for multiple material systems; has simple preparation process; is diversified by designing the anode; improves low temperature direct current internal resistance of the battery; improves battery performance by synergistically improving the low-temperature rate discharge and low-temperature rate charging performance; has simple preparation method; and is economical. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for an ion battery.
