Description

technical field [0001] The invention belongs to the technical field of electrochemical energy storage, and relates to a three-dimensional porous structure electrolyte with organic / inorganic network interpenetration and a preparation method thereof. Background technique [0002] With the continuous consumption of fossil fuels and the continuous emission of greenhouse gases, green and renewable electrical energy sources have been widely developed, such as solar energy, wind energy, tidal energy, geothermal energy, nuclear energy and electrochemical energy storage. Due to the challenges such as being affected by weather, geographical distribution, etc., these renewable electric energy sources will generate strong intermittency and randomness. Therefore, large-scale structural components are expected to be combined with the above-mentioned renewable electric energy sources to solve this problem, including electrochemical energy storage (battery), thermal energy storage (high tem...
