1, 1970s Exxon's M.S.Whittingham using titanium sulfide as a cathode material, metal lithium as a negative material, made of the first lithium battery.
2, 1980, J. Goodenough found that lithium cobalt oxide can be used as a lithium ion battery cathode material.
R.R.Agarwal and J.R.Selman of the Illinois Institute of Technology in 1982 found that lithium ions had the characteristics of embedded graphite, and the process was fast and reversible. At the same time, the use of lithium metal lithium battery, its security risks of concern, so people try to use lithium-ion embedded graphite characteristics of the production of rechargeable batteries. The first available lithium-ion graphite electrode was successfully manufactured by Bell Labs.
4, 1983 M.Thackeray, J. Gingenough et al. Found that manganese spinel is an excellent cathode material with low cost, stable and excellent conductivity and conductivity. Its decomposition temperature is high, and the oxidation is much lower than the lithium cobalt oxide, even if the short circuit, overcharge, but also to avoid the risk of combustion, explosion.
5, 1989, A. Manthiram and J. Gingenough found that the use of polymerization of anionic cathode will produce a higher voltage.
6, 1991 Sony Corporation released the first commercial lithium-ion battery. Subsequently, lithium-ion battery innovation in the face of consumer electronics products.
7, 1996 Padhi and Goodenough found that with the olivine structure of phosphate, such as lithium iron phosphate (LiFePO4), than the traditional cathode material is more superior, it has become the current mainstream cathode material.
With the widespread use of digital products such as mobile phones, laptops and other products, lithium-ion batteries with excellent performance in these products are widely used, and gradually to other product applications. In 1998, Tianjin Electric Power Research Institute began commercial production of lithium-ion battery. It is customary for people to use lithium-ion batteries as lithium batteries, but these two batteries are not the same. Lithium-ion battery has become the mainstream.
