Lithium-ion batteries can be roughly divided into three major areas from the application scenario: 3C electronic products (computer, communication and consumer electronics), electric vehicles and large-scale static energy storage.

　　Due to different application scenarios, there are also large differences in the requirements for comprehensive performance indicators of lithium-ion batteries.

　　In the field of 3C electronic products, lithium-ion batteries almost occupie the overall market, and in terms of electric vehicles, the power battery market dominated by lithium-ion batteries continues to expand.

　　In the future, as the cost of lithium-ion batteries continues to decrease and performance continues to improve, the cost-effectiveness of electric vehicles is expected to surpass that of fuel vehicles in 2035, thus realizing the full electrification of vehicles.

　　Lithium-ion batteries have begun to have commercial demonstrations in some special fields and regions. In December 2019, an all-electric DHC-2 (DHC-2 de Havilland Beaver) seaplane of Australia's Harbour Air carried out a test flight. Although it was limited by the energy density of the power battery and its own weight, the flight lasted less than 15 minutes, but it did. It is the first flight test of an all-electric commercial airliner.

　　Lithium-ion batteries have huge application potential in large-scale energy storage, especially lithium iron phosphate batteries with high safety, because they can perfectly replace lead-acid batteries.

　　In the future, how to develop a safe, efficient, low-cost, large-scale and long-life lithium-ion battery will be the key to its success in the relevant power battery and energy storage market.

　　From the current global research and development direction, the use of solid electrolytes to replace organic combustible liquid electrolytes is a mainstream trend to improve the safety of lithium-ion batteries.
