With the increasing proportion of renewable energy in the global energy mix, efficient and reliable energy storage sources have become the key to ensuring the stability of power supply. Energy storage systems can store excess energy and release it during peak demand, thereby balancing supply and demand and supporting the stability of the power grid.

Lithium ion batteries are currently the most mainstream energy storage technology, favored for their high energy density and long cycle life. However, with the growth of energy demand and the increasing demand for sustainable solutions, researchers are exploring more sustainable and higher energy density energy storage materials and designs, such as flow cells, solid-state batteries, and fuel cells.

Efficient energy storage technology can not only improve the utilization of renewable energy, but also provide electricity to off grid areas, enhance the flexibility of the power system, and provide backup power in emergency situations. With the continuous advancement of technology and the decrease in costs, energy storage power sources are becoming increasingly important.
