NOVELTY - Anode plate, is claimed. The active material of the anode plate comprises poly triphenylamine (I) and/or their derivatives (II). USE - The anode plate is useful in sodium ion battery (claimed). ADVANTAGE - The anode plate: utilizes the excellent power and cycle performance of poly triphenylamine and their derivatives, and solves the problem of low power performance commonly existing in the current inorganic sodium ion anode materials; produces sodium-ion battery, which is simple in preparation process, low in cost, environmentally friendly, and has very high economic value and research significance. DETAILED DESCRIPTION - Anode plate, is claimed. The active material of the anode plate comprises poly triphenylamine of formula (I) and/or their derivatives of formula (II). R = -H, -CN, -NO2 or-SO3; n = 40-400. INDEPENDENT CLAIMS are also included for: Sodium ion battery, comprising sodium ion battery anode plate. (1) Preparing anode plate, comprising (1) mixing main polymer anode material with a conductive agent and a binder with NMP to obtain an anode slurry; (2) coating the anode slurry on the surface of the aluminum foil, rolling and drying to obtain final product;
