Data show that Ni-MH batteries dominate 90% of the global automotive battery market, and Japan has the most core technology. Ni-MH battery has stable performance, mature technology and high degree of industrialization, and will become the key development direction of domestic new energy in the next 5 years

　　At present, the entire market has much discussion on the application prospects of lithium-ion batteries in the field of new energy vehicles. However, its application prospects in traditional fields have received little attention. Through detailed research on the application of lithium-ion batteries in important application areas, it is found that even if the development of new energy vehicles is lower than expected, the development prospects of the lithium-ion battery industry are still optimistic.

　　Currently, notebook computers and mobile phones are still two important markets for lithium-ion batteries. In the future, the portability and platformization of personal computers will continue to drive the rapid rise in demand for lithium-ion batteries. Smart phones and touch screen phones will also ensure a steady increase in shipments. Lithium-ion batteries are also expected to be used in digital cameras, handheld computers, e-books, power tools, electric bicycles, and communication backup power sources.

　　Through the summary and analysis of the demand for lithium-ion batteries, we found that the total capacity of the important global small lithium-ion battery market in 2016 was approximately 52.6 billion yuan. By 2015, the market capacity will reach about 106.9 billion yuan, twice the current level. In the next 5 years, the small lithium-ion battery market will continue to increase at an average annual rate of about 15%. The subsequent development of small lithium-ion batteries will provide stable support for the development of the lithium-ion battery industry.

　　In the next few years, the overall trend of the lithium-ion battery market will be good. By 2020, my country's lithium-ion battery market is expected to reach 20.533 billion kilowatt hours, with a compound annual growth rate of 41.88% in the next two years. Under the guidance of national policies such as double points, power lithium batteries will become an important rising point, with a CAGR of 56.32% in the next two years. Digital batteries will be driven by the high-end digital battery market, with a compound annual growth rate of 7.87% in the next two years; in the field of energy storage batteries, due to the reduction in the cost of lithium-ion batteries and the increase in lead orders, the replacement of lead-acid batteries will gradually accelerate to 35.16%.

　　The rapid development of lithium-ion batteries in my country is mainly due to the strong support of the national new energy vehicle policy. In 2018, my country's new energy vehicle production increased by 50.62% year-on-year to 1.22 million vehicles, 14.66 times that of 2014. Driven by the development of the new energy vehicle market, my country's power lithium battery market maintained a rapid rise from 2017 to 2018. According to research statistics, the output of power lithium battery market in 2018 increased by 46.07% year-on-year to 65gwh.
