The most potential development area of lithium-ion batteries - Energy Storage

　　In the past, due to the small size of the energy storage industry, the energy storage business of various enterprises accounted for a relatively low proportion and the business volume was small.

　　In recent years, with the reduction of industrial costs and the promotion of demand, the energy storage business has made rapid progress.

　　Generalized energy storage includes three types of electrical energy storage, thermal energy storage and hydrogen energy storage, of which electrical energy storage is the main one.

　　Electric energy storage is divided into electrochemical energy storage and mechanical energy storage. Electrochemical energy storage is currently the most widely used power storage technology with the greatest potential for development. It has the advantages of being less affected by geographical conditions, short construction period, and economical.

　　In terms of structural types, electrochemical energy storage mainly includes lithium-ion batteries, lead storage batteries, and sodium-sulfur batteries. Lithium-ion energy storage batteries have the characteristics of long life, high energy density, and strong environmental adaptability. As the commercialization route matures and costs continue to decrease, lithium-ion batteries are gradually replacing low-priced lead storage batteries, which are superior in performance.

　　Lithium-ion batteries can be classified into consumption, power and energy storage batteries according to their application fields.

　　The mainstream battery types of energy storage batteries include lithium iron phosphate batteries and ternary lithium batteries. With the solution of the energy density problem of lithium iron phosphate batteries, the proportion of lithium iron phosphate batteries has increased year by year.

　　Lithium iron phosphate battery has strong thermal stability and high structural stability of the positive electrode material. Its safety and cycle life are better than ternary lithium batteries, and it does not contain precious metals. It has a comprehensive cost advantage and is more in line with the requirements of energy storage systems.
