In the 1970s, Exxon's M.S. Whittingham used titanium sulfide as the positive electrode material and lithium metal as the negative electrode material to create the first lithium battery.
In 1980, J. Goodenough discovered that lithium cobalt oxide could be used as a cathode material for lithium-ion batteries.
In 1982, R.R. Agarwal and J.R. Selman of the Illinois Institute of Technology discovered that lithium ions have the particularity of incorporating graphite. This process is quick and reversible. At the same time, the safety risks of lithium metal batteries have attracted a lot of attention, so people have tried to use the characteristics of lithium ions embedded in graphite to make rechargeable batteries. The first usable lithium-ion graphite electrode was successfully produced by Bell Laboratories.
In 1983, M. Thackeray, J. Goodenough and others found that manganese spinel is an excellent cathode material with low price, stability, and excellent lithium conductivity and conductivity. Its decomposition temperature is high and its oxidation property is much lower than that of lithium cobalt oxide. Even in the event of a short circuit or overload, it can avoid the risk of burns and explosions.
In 1989, A.Manthiram and J.Goodenough discovered that a positive electrode using polymer anions would produce a higher voltage.
In 1991, Sony released the first commercial lithium-ion battery. Later, lithium-ion batteries revolutionized consumer electronics.
In 1996, Padhi and Goodenough discovered that phosphates with an olivine structure, such as lithium iron phosphate (LiFePO4), are superior to traditional cathode materials and thus have become the common cathode materials todays.
With the widespread use of digital products such as mobile phones and notebook computers, lithium-ion batteries have been widely used in these products due to their excellent performance and are gradually developing into more other product application areas.
In 1998, Tianjin Energy Source Research Institute began commercial production of lithium-ion batteries.
On July 15, 2018, we learned from Keda Coal Chemistry Research Institute that a special carbon anode material for high capacity and high density lithium batteries, composed of pure carbon as the main component, was launched at the institute. This type of lithium batteries made from new materials can achieve a range of more than 600 kilometers.
In October 2018, the research group of professors Liang Jiajie and Chen Yongsheng from Nankai University andThe research group of Jiangsu Lai Chao Normal University successfully prepared a three-dimensional porous support of silver-graphene nanowires with a hierarchical structure. and loaded it with lithium metal as a composite anode material. This media can inhibit the generation of lithium dendrites, thereby enabling ultra-fast charging of batteries, which should significantly extend the "life" of lithium batteries. The research results were published in the latest issue of “Advanced Materials”.
