Lithium battery development process

2021-08-10

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

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 properties of being embedded in graphite, a process that is rapid and reversible.  At the same time, the safety risks of lithium batteries made of lithium metal have attracted much attention, so people try to use the characteristics of lithium ion embedded graphite to make rechargeable batteries.  The first usable li-ion graphite electrode was trialled by Bell Laboratories.  

In 1983, M. Hackeray, J.Goodenough et al. 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 the oxidation is far lower than lithium cobalt oxide, even if short circuit, overcharge, can also avoid the danger of combustion, explosion.  

In 1989, A.Manthiram and J.Goodenough discovered that a positive electrode with a polymeric anion produces a higher voltage.  

1991 SONY released the first commercial lithium-ion battery.  Then lithium ion batteries revolutionised consumer electronics.  

In 1996, Padhi and Goodenough discovered that phosphates with olivine structure, such as lithium iron phosphate (LiFePO4), are superior to traditional cathode materials, so they have become the current mainstream cathode materials.  

With the wide use of digital products such as mobile phones, notebook computers and other products, lithium ion battery has been widely used in this kind of products with excellent performance, and is gradually developing to other product application fields.  

In 1998, tianjin Power Supply Research Institute began commercial production of lithium-ion batteries.  

On July 15, 2018, it was learned from coda Coal Chemistry Research Institute that a special carbon cathode material for high capacity and high density lithium battery made of pure carbon as the main component was published in the institute. This kind of lithium battery made of new material can achieve a car range of more than 600 kilometers.  [1]  

In October 2018, professor Liang Jiajie and Chen Yongsheng's group from Nankai University and Professor Lai Chao's group from Jiangsu Normal University successfully prepared a multistage structure of silver nanowires -- graphene three-dimensional porous carrier, and supported by lithium metal as composite cathode material.  This carrier can inhibit the production of lithium dendrite, which can achieve super high-speed battery charging, is expected to greatly extend the "life" of lithium battery.  The research is published in the latest issue of advanced Materials
