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...
