  Li-ion 18650 3200mAh 3.7V

  In the 1970s, M.S. Whittingham of Exxon made the first lithium battery by using titanium sulfide as the cathode material and lithium metal as the cathode material.

  2. In 1980, J Goodnough found that lithium cobalate can be used as cathode material of lithium ion battery

  3 In 1982, R.R. Agarwal and J.R. Selman of the Illinois Institute of Technology found that lithium ion has the property of embedding graphite, and this process is rapid and reversible. At the same time, the potential safety hazard of lithium batteries made of lithium metal has attracted much attention. Therefore, people try to make rechargeable batteries using the characteristics of lithium ions embedded in graphite. The first available lithium ion graphite electrode was successfully trial manufactured by Bell Laboratories.

  4 In 1983, M. Thackeray, J. Goodenough and others found that manganese spinel is an excellent cathode material with low price, stability and excellent conductivity and lithium conductivity. Its decomposition temperature is high, and its oxidizability is far lower than that of lithium cobalate. Even in the event of short circuit and overcharge, it can also avoid the danger of combustion and explosion.

  5 In 1989, A. Manthiram and J. Goodnough found that the positive electrode with polymeric anions will produce higher voltage.

  In 1991, Sony released the first commercial lithium-ion battery. Subsequently, lithium-ion batteries revolutionized the face of consumer electronics.
