Battery for Energy Storage & Electric Vehicle Lead-acid batteries for energy storage suitable for solar, wind and other new energy power generation equipment. Energy storage technology is widely used and has huge market potential. It is a key link in the energy Internet, which is mainly reflected in the following aspects: First, the output power of intermittent power sources such as photovoltaic and wind power is unstable. When its power generation ratio reaches a high, it will have a certain impact on the power grid, so a certain proportion of energy storage is needed to stabilize the output power of photovoltaic and wind power stations. Second, in areas where electricity prices are higher than on-grid electricity prices, and where peak and trough electricity prices vary greatly, distributed energy storage is often very economical; microgrids and off-grids also have direct demands for energy storage. Third, the application of energy storage in the power system will change the synchronized mode of electric energy production, transmission and use, make up for the missing "storage and release" function in the power system, and achieve the purpose of optimizing the allocation of power resources and improving energy efficiency. Fourth, advances in energy storage technology have also driven the rapid development of electric vehicles. Lead-acid batteries are currently the better choice among energy storage batteries. From the perspective of cost, lead-acid batteries are more economical than other chemical energy storage methods such as lithium batteries. From the perspective of product performance, lead-acid batteries have mature technology, high safety, and a wide applicable temperature range; lithium batteries have problems such as consistency in the application of large battery packs, and safety problems in large power battery cells. Lead-acid batteries further improves the performance of the battery, greatly increases the number of cycles, and reduces the cost per unit use. Lead-acid batteries have relatively good application prospects in the field of energy storage.   3.
