▎ 摘　　要

NOVELTY - The battery has an electrolyte comprising conductive positive ion and conductive negative ion. An anode pole piece which is immersed in the electrolyte solution. The anode sheet comprises anode current collector and anode material layer. The anode material layer is covered on the anode collector. The anode material layer comprises a sodium-containing material, graphite material, conductive agent and agglomerant. In the battery charging process, the sodium-containing material is used for providing a carrier of the conductive positive ions. The graphite material is used for providing embedded carrier for the conductive negative ion in the battery discharge process. The sodium-containing material is used for providing embedded carrier for the conductive positive ion. The graphite material is used for providing the carrier for removing the conductive negative ion. USE - The battery i.e. lithium-ion battery for use in a vehicle, preferably lead-acid battery and a sodium ion battery. ADVANTAGE - The battery concentration of the electrolyte in the battery charging and discharging process can be kept in a certain range, preventing the battery internal resistance is increased, increasing the battery safety and energy efficiency at the same time the battery has a higher energy density. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a preparation method of battery.
