Information

The mainstream battery types of energy storage battery 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 energy storage battery requirements.

Energy storage battery focuses on battery capacity, stability and life, and considers battery module consistency, battery material expansion rate and energy density, electrode material performance uniformity and other requirements to achieve a longer life and lower cost, and the number of cycles of energy storage batteries The life span is generally required to be greater than 3500 times.

From the perspective of application scenarios, energy storage battery is mainly used in peak and frequency modulation power auxiliary services, renewable energy grid-connected, micro-grid and other fields.

In the past, due to the small size of the energy storage industry and the fact that it has not yet entered the full economic point of time, the energy storage business of various companies has a relatively low share of the energy storage business and the business volume is small. In recent years, with the reduction of industrial costs and the promotion of demand, the energy storage business Make 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 electric energy storage technology with the greatest potential for development. It is less affected by geographical conditions, short construction period, and economical. Advantage.

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. With the maturity of commercialization routes and the continuous reduction of costs, lithium-ion batteries are gradually replacing low-cost 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.
