Abstract

The invention discloses a polyacrylate-based polymer electrolyte for a sodium battery and a polymer sodium battery formed from the polyacrylate-based polymer electrolyte. The polyacrylate-based polymer electrolyte has favorable electrochemical stability and relatively high ion transmission performance and is obtained by applying an in-situ polymerization process, and a precursor of the polyacrylate-based polymer electrolyte comprises a sodium salt, a non-aqueous organic solvent, a polymerizable monomer and an initiator; meanwhile, the sodium battery assembled by applying the polymer electrolyte disclosed by the invention is stable in a charging / discharging curve and has favorable long circulation and rate charging / discharging performance; and moreover, the preparation process of the polymer electrolyte is the same as a traditional commercial lithium battery production process, the polymer electrolyte is simple to prepare and easy to form on the premise of not changing the original battery production process. Therefore, the polyacrylate-based polymer electrolyte prepared through in-situ polymerization, proposed by the invention, is applicable for the field of the sodium battery, and has great commercial potential.

Description

technical field

[0001] The invention relates to a polymer electrolyte, in particular to a polyacrylate-based polymer electrolyte for a sodium battery and a polymer sodium battery formed thereof. Background technique

[0002] The renewable clean energy currently being developed includes wind energy, solar energy, and tidal energy. They are all intermittent energy sources. If the intermittent and unstable electric energy generated by them is incorporated into the grid, it will seriously interfere with the normal operation of the grid. Therefore, the development It has become a worldwide research hotspot to develop new energy storage technologies that meet large-scale energy storage applications, low cost, high safety, and large scale. At present, the main energy storage technologies include electrochemical energy storage, mechanical energy storage, electromagnetic energy storage and phase change energy storage. Compared with other energy storage methods, electrochemical energ...
