Recent progress and future prospects of high-entropy materials for battery applications

Due to the energy crisis caused by limited fossil fuel reserves, extensive use of the renewable energy sources such as wind or solar energy is deemed to replace the use of traditional fossil fuels in the future[1?3]. However, most renewable energy sources face the same problem, which is the intermittency of energy. For example, solar energy cannot be utilized at night. That means the continuous energy demand required for large-scale power grids can't be satisfied by a single solar panel model.
