Explain the development stage of lithium batteries

Introduction to Lithium Battery Lithium battery is a kind of battery made by using lithium metal or lithium alloy as negative electrode material and using non-aqueous electrolyte solution invented by Edison in the early days. Its working principle is the oxidation-reduction reaction of Li+MnO2u003dLiMnO2. Due to its active chemical properties, lithium has not been widely used for a long time. However, with the rapid development of science and technology, lithium batteries have gradually become the mainstream. Lithium battery development stage 1. In the 1970s, m.s. Watson of Exxon Mobil Corporation used titanium sulfide as positive electrode data and metal lithium as negative electrode data to make the world's first lithium battery. 2. In 1980, J. Goodenough discovered that lithium cobalt oxide can be used as anode data for lithium batteries. 3. In 1982, the mercury sphygmomanometer argarwal and sielman of the Illinois Institute of Technology discovered that lithium ions have the characteristic of intercalating graphite, which is a fast and reversible process. At the same time, lithium batteries are made of lithium metal, and their safety hazards are worrying. Therefore, people have tested the use of lithium ions embedded in graphite to make rechargeable batteries. The first available lithium ion graphite electrode was successfully trial-produced by Bell Laboratories. 4. In 1983, m.hackeray and j.gendenough et al. discovered that manganese spinel is an excellent positive electrode material with low price, stable and excellent conductivity and lithium conductivity. Its decomposition temperature is high, and the oxidation degree is much lower than that of lithium cobalt oxide. Even short-circuit or overcharge, it can prevent burning and explosion hazards. 5. In 1989, A. Manthiram and J. Gough found that when a positive electrode with polymerized anions was selected, a higher voltage would appear. 6. Sony announced the first commercial lithium battery in 1991. Later, lithium batteries revolutionized consumer electronics. 7. In 1996, Padhi and Goodenough discovered that phosphates with an olivine structure, such as lithium iron phosphate (LiFePO4), were superior to conventional positive electrode data and became the mainstream positive electrode data at that time.
