Lithium Battery Development Process

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.
