1. 1970s Exxon M.S.Whittingham using titanium sulfide as the cathode material, lithium metal as the anode material, made the first lithium battery.
2, 1980, J. Goodenough found that lithium cobalt oxide can be used as lithium-ion battery cathode material.
3. R.R.Agarwal and J.R. Selman, 1982, of the Illinois Institute of Technology, have found that lithium ions have the property of intercalating graphite, a process that is fast and reversible. At the same time, the use of lithium metal lithium battery, the concern of security risks, so people try to use lithium-ion graphite embedded in the characteristics of the production of rechargeable batteries. The first available lithium-ion graphite electrode trial by the Bell laboratory success.
In 1983, M.Thackeray, J.Goodenough, who found that manganese spinel is an excellent cathode material, with low price, stability and excellent conductivity, lithium conductivity. Its decomposition temperature is high, and the oxidation is much lower than lithium cobalt oxide, even if there is a short circuit, overcharge, but also to avoid the risk of burning, explosion.
5. 1989, A. Manthiram and J. Goodenough found that the use of polyanion positive electrode will produce a higher voltage.
6, 1991, Sony released the first commercial lithium-ion battery. Subsequently, lithium-ion battery innovation consumer electronics products.
7,1996 Padhi and Goodenough found that olivine-containing phosphates, such as LiFePO4, are superior to traditional cathode materials and have become the current mainstream cathode materials.
With the widespread use of digital products such as cell phones, laptops and other products, lithium-ion batteries have been widely used in such products with excellent performance and are gradually being applied to other product applications. In 1998, Tianjin Power Research Institute began commercial production of lithium-ion batteries. Traditionally, lithium-ion batteries are also known as lithium batteries, but the two batteries are not the same. Lithium-ion battery has become the mainstream.
