▎ 摘　　要

NOVELTY - Sodium ion battery sheet comprises an anode active material arranged on the surface of an anode collector. The anode active material comprises a deintercalation type anode material and an adsorption type anode material. The amount of anode active material on the surface of the anode current collector is 0.2-0.8 g per square decimeter. The weight ratio of the deintercalation type anode material and the adsorption type anode material is (65-85):(30-10). The deintercalation anode material comprising at least one of layered structure sodium ion compounds, polyanionic sodium ion compounds, Prussian blue compounds and/or carbonyl compounds. The deintercalation anode material comprises NaxMO2(M comprising at least one of cobalt, iron, manganese and/or nickel), perylenetetracarboxylic dianhydride (PTCDA) and sodium vanadium fluorophosphate. The absorbing anode material comprises active carbon and/or graphene. USE - The sodium ion battery sheet is useful in high power batteries and hybrid vehicles (all claimed). ADVANTAGE - The sodium ion battery sheet has power density of 2-3.5 kw/kg, and the energy density of 40-80Wh/kg thus meets the usage requirements of hybrid electric vehicle packs. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are also included for: Sodium ion battery; and Application of sodium ion battery sheet in high power batteries with discharge rate of 30-100C.
