At present, the technical application of lithium battery in energy storage mainly focuses on the fields of grid base station standby power supply, home optical storage system, electric vehicles and charging stations, electric tools, home office equipment and other fields. During the 13th Five Year Plan period, China’s energy storage market will take the lead in the field of public utilities, with penetration from the power generation and transmission side to the user side. According to the data, the application volume of lithium battery energy storage market in 2017 was about 5.8gwh, and the market share of lithium-ion battery will continue to increase steadily year by year in 2018.

According to the application scenarios, lithium-ion batteries can be divided into consumption, power and energy storage. At present, the power lithium battery and energy storage lithium battery are highly valued in the industry. According to the prediction of authoritative experts, the proportion of power lithium battery in all applications of lithium battery in China is expected to rise to 70% by 2020, and power battery will become the main force of lithium battery. Power lithium battery will become the main force of lithium battery

The rapid development of lithium battery industry is mainly due to the policy promoting the development of new energy vehicle industry. In April 2017, the Ministry of industry and information technology of the people’s Republic of China also mentioned in the latest “medium and long term development plan of automobile industry” that the production and sales of new energy vehicles should reach 2 million in 2020, and that new energy vehicles should account for more than 20% of automobile production and sales by 2025. It can be seen that new energy and green energy-saving and other environmental protection industries will become the important pillar industries of society in the future.

In the future trend of power battery technology, ternary is becoming a major trend. Compared with lithium cobalt oxide, lithium iron phosphate and lithium manganese dioxide batteries, ternary lithium battery has the characteristics of high energy density, high voltage platform, high tap density, good cycle performance, electrochemical stability and so on. It has obvious advantages in improving the range of new energy vehicles. At the same time, it also has the advantages of high output power, good low temperature performance, and can adapt to all-weather temperature. For electric vehicles, it is no doubt that most consumers are concerned about its endurance and safety, and lithium-ion battery is obviously a better choice.

With the rapid increase of electric vehicle demand, the demand for power lithium-ion battery has increased significantly, which has become the main force driving the growth of lithium-ion battery industry. Lithium battery is a very tough product. It was born in the 1980s and has undergone a long time of precipitation and technological innovation. At the same time, no matter the production or destruction process of lithium battery does little harm to the environment, which is more in line with the demands of the current social development. Therefore, lithium battery has become the core focus of the new generation of energy. In the medium term, the current transportation technology upgrading is the core of global application technology upgrading. As an indispensable supporting product for transportation technology upgrading, power lithium battery is expected to have great development in the next 3-5 years.
