Abstract

The invention discloses a plastic electrode and its preparation method, as well as a water-based sodium ion battery and its preparation method. The preparation method of the plastic electrode includes: mixing electrolyte salt and deionized water into an electrolyte solution; adding a surfactant and a moisturizing agent into the electrolyte solution , mix into a uniform solvent matrix; add the conductive material into the solvent matrix, and disperse the conductive material evenly in the solvent matrix; add positive / negative active materials and binders; A water-based sodium-ion battery plastic electrode paste with a three-dimensional network structure formed by cross-linking of the binder. The plastic electrode of the present invention is a stable mixture of active material and electrolyte, the electrolyte is locked in the plastic electrode, the ion diffusion path is reduced when the battery is charged and discharged, the ionic impedance and electronic impedance are greatly reduced, and it is beneficial to large-scale output; the preparation and operation of the electrode of the present invention The battery assembly is completed synchronously, and the liquid injection process is omitted, which simplifies the battery preparation process.

Description

technical field [0001] The invention belongs to the field of water-based battery materials, and in particular relates to a plastic electrode and a preparation method thereof, and a water-based sodium ion battery and a preparation method thereof. Background technique [0002] So far, resource-based fossil fuels are still the main source of electricity supply for human beings. The carbon emission caused by its extensive use is the main cause of the current global greenhouse effect. Intermittent renewable energy represented by solar and wind energy must be connected to the grid through the storage and release of energy storage systems. Therefore, large-scale energy storage technology is the basis for the promotion of new energy and energy innovation, and is an important part of the national energy strategic demand layout. It plays an important role in the optimization of the national energy structure and the safe and stable operation of the power grid. Due to the advantages o...
