By 2005, the output of lithium-ion batteries had reached 2.35 billion, and the development was quite rapid. Lithium-ion batteries were mainly used in various portable electronic products in the 1990s. With the continuous development of battery technology, the energy density of lithium-ion batteries has continued to increase, and the scope of application has also continued to expand. It has expanded from information products to energy transportation and other fields.

Lithium-ion battery technology is no longer a single industrial technology, it has become one of the foundations for the development of new energy. According to statistics, China’s current battery output has exceeded 10 billion, and it has become the largest producer and consumer of the battery industry. The average annual output value of this industry exceeds 4 billion US dollars, and the lithium battery market will continue to grow rapidly in the next few years, with huge market potential. Once a breakthrough in power battery technology is achieved, electric vehicles are likely to replace fuel vehicles and become the mainstream. At that time, the demand for lithium-ion batteries will increase sharply, bringing huge market value.

Low cost, high performance, high safety and environmental protection are the development aspects of lithium-ion batteries in the future. As a representative of new energy, lithium-ion batteries have obvious advantages, but there are also disadvantages that need to be improved. Although a lot of progress has been made in the research of electrode materials and electrolytes in recent years, there is still a certain gap between the goal of the next generation of lithium-ion batteries.

As more and more cars are used in China, environmental problems have become acute. In order to solve the environmental pollution caused by cars, the use of electric cars is an inevitable result of future social development. However, although there are small batches of electric vehicles in the current market, due to the high cost, ordinary people cannot buy such expensive vehicles, which limits the promotion of electric vehicles. At the same time, the safety of lithium-ion batteries is not good. There have been many fire accidents. The most fundamental reason that restricts the development of electric vehicles is that the mileage of electric vehicles currently in use is too small, and the charging time is less than 120km.

In order to commercialize electric vehicles, look for high-performance positive and negative materials to increase the driving range of electric vehicles, and to make the battery safer through the design of the battery system, while reducing the cost of the battery, it is best to have about 30,000 yuan A small car and can guarantee a driving range of more than 200km, so that electric vehicles can be developed rapidly in China.

The research of lithium-ion batteries is an intersecting field involving many disciplines such as physics, chemistry, materials, electronics, and energy. With the continuous deepening of research, the overall design of lithium-ion batteries will be more reasonable and will eventually be widely used in various fields. Lithium-ion batteries have created brilliance, and the future will surely have greater brilliance.
