Abstract

The invention relates to a synchronous reaction-based polymer/cement composite material structure electrolyte preparation method, and the method comprises: (1) weighing an organic polymer monomer, dissolving the organic polymer monomer in deionized water, and performing complete stirring to obtain an organic polymer monomer aqueous solution; (2) weighing an ionic electrolyte, adding the ionic electrolyte into the organic polymer monomer aqueous solution, and performing full stirring to obtain an organic polymer monomer electrolyte; (3) adding cement powder and an initiator into the organic polymer monomer electrolyte, and performing full stirring to obtain uniform slurry; (4) pouring the uniform slurry into a mold, performing hardening, molding, curing and demolding to obtain the solid block structure electrolyte, namely the target product. Compared with the prior art, the polymer/cement composite material structure electrolyte has the advantages that the good interface compatibility of a structure phase and a conductive phase in the structure electrolyte is improved, and meanwhile, the comprehensive balance of mechanical properties and electrical properties is also realized.

Description

technical field [0001] The invention belongs to the technical field of structural energy storage materials, and relates to a synchronous reaction-based polymer / cement composite structural electrolyte and a preparation method thereof. Background technique [0002] With the rapid development of the global economy, the depletion of fossil fuels and the increasing environmental pollution have brought many difficulties to human beings. So we are looking for an efficient, clean and sustainable energy to replace traditional fossil energy. However, the use of renewable energy led by solar energy is always fluctuating and unstable, and there is a problem of time-space mismatch with the actual use of energy. Energy storage refers to the process of storing energy through a medium or device and releasing it when needed. Energy storage technology is a key technology to solve the problems of large-scale access to renewable energy and abandoning wind and light; it is an essential technol...
