Description

technical field [0001] The invention relates to the field of batteries, in particular to a high-energy solid-state battery and a preparation method thereof. Background technique [0002] Since the beginning of the 21st century, with the progress of civilization and economic development, human needs and dependence on energy are increasing. However, traditional fossil energy is facing exhaustion, and people's demand for energy tends to be sustainable and environmentally friendly. system. There are many renewable and clean energy sources in nature, such as solar energy, wind energy, tidal energy, etc. These energy sources can be converted into electrical energy for use. Among them, the new energy sources represented by wind energy and solar energy have a common feature, that is, the total amount is large, but scattered. , low energy density, intermittent and random, it is difficult to be used on a large scale. Therefore, as a simple and efficient energy storage and supply dev...
