With the development of science and technology, lithium batteries have become the mainstream and are mainly used in power lithium batteries and energy storage in emerging fields. In 2019, the global lithium battery industry market scale reached 49.3 billion US dollars, China's about 18.4 billion US dollars, Japan's about 14.9 billion US dollars, and South Korea's about 13 billion US dollars. The following is the meaning and classification analysis of lithium battery industry.
China, Japan and South Korea have formed a tripartite lithium battery industry. Before 2000, more than 88% of lithium batteries in the world were produced in Japan; After 2000, China and South Korea have successively invested in the lithium battery industry and mass production, forming a tripartite confrontation with Japan. At present, lithium batteries produced in China, Japan and South Korea account for more than 95% of the global production.(Lithium - Ion Battery Equipment)
According to the analysis data of lithium battery industry, as of December 2019, China's lithium battery market output increased by 26.71% year-on-year to 102.00GWh, and the installed capacity of CATL, BYD, Waterma, Guoxuan Hi-Tech, Bike, and Funeng Technology exceeded 1GWh, with a relatively high market share. China accounts for 54.03% of global output, and has become the largest lithium battery manufacturer in the world.
Lithium battery is a kind of battery with lithium metal or lithium alloy as anode material and non-aqueous electrolyte solution. In 1912, lithium metal batteries were first proposed and studied by Gilbert N. Lewis. In the 1970s, M.S. Whittingham proposed and began to study lithium batteries. Due to the very active chemical properties of lithium metal, the processing, storage and use of lithium metal have very high environmental requirements. With the development of science and technology, lithium battery has become the mainstream.
The meaning and classification of lithium battery industry points out that the lithium battery on the market can be roughly divided into two categories: lithium metal battery and lithium battery.
1. Lithium metal battery
Lithium metal battery was developed by SolidEngergy, which was born at MIT. This technology can reduce the volume of current lithium battery by half and can be used in electric vehicles in the future. Although graphite has been proved to be the best and most reliable material for making cathode, it contains a limited number of ions. Researchers have always hoped to replace graphite with lithium metal foil, which can hold more ions, but usually lithium metal foil and electrolyte will have adverse reactions, which will lead to electrolyte overheating and even lead to combustion.
2. Lithium battery
Lithium battery is a kind of secondary battery, which mainly depends on the movement of lithium ion between the positive electrode and the negative electrode. In the process of charging and discharging, Li+is embedded and de-embedded between the two electrodes: during charging, Li+is de-embedded from the positive electrode and embedded into the negative electrode through the electrolyte, and the negative electrode is in a lithium-rich state; The opposite is true when discharging. The meaning and classification of lithium battery industry pointed out that on October 9, 2019, the Royal Swedish Academy of Sciences announced that the 2019 Nobel Prize in Chemistry would be awarded to John Gudinav, Stanley Whittingham and Yoshino in recognition of their contributions in the field of lithium battery research and development.
At present, China's lithium battery industry has gradually formed an oligopoly, with CATL and BYD firmly occupying the first echelon, with a market share of more than 70%. In the early years, BYD's lithium iron phosphate battery dominated the world, and in the later period, CATL's ternary lithium battery came from behind; Combined with the new changes in the post-subsidy era, lithium iron phosphate battery is expected to gain a second spring.
