Analysis of the development process of lithium batteries!

Date of Issue:2020-07-01 Click:

In the 1970s, Exxon’s M.S. Whittingham used titanium sulfide as the cathode material and metallic lithium as the anode material to make the first lithium battery.

In 1980, J. Goodenough discovered that lithium cobalt oxide can 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 characteristics of intercalating graphite. This process is fast and reversible. At the same time, the safety hazards of lithium batteries made of metal lithium have attracted much attention. Therefore, people have tried to make rechargeable batteries using the characteristics of lithium ions embedded in graphite. The first available lithium ion graphite electrode was successfully trial-produced by Bell Laboratories.

In 1983, M. Thackeray, J. Goodenough, and others discovered 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 oxidation is much lower than that of lithium cobalt oxide. Even if there is a short circuit or overcharge, it can avoid the danger of combustion and explosion.

In 1989, A. Manthiram and J. Goodenough discovered that a positive electrode with a polymer anion would produce a higher voltage.

Sony released the first commercial lithium-ion battery in 1991. Subsequently, lithium-ion batteries revolutionized the face of 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 therefore have become the current mainstream cathode materials.

With the widespread use of digital products such as mobile phones and notebook computers, lithium-ion batteries have been widely used in such products with excellent performance and are gradually developing into other product applications.

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

On July 15, 2018, it was learned from the Keda Coal Chemistry Research Institute that a special carbon anode material for high-capacity and high-density lithium batteries with pure carbon as the main component came out in the institute. This kind of lithium battery made of new materials The car's cruising range can exceed 600 kilometers.

In October 2018, the research group of Professor Liang Jiajie and Chen Yongsheng of Nankai University and the research group of Lai Chao of Jiangsu Normal University successfully prepared a silver nanowire-graphene three-dimensional porous carrier with a hierarchical structure, and loaded metal lithium as a composite anode material. This carrier can inhibit the generation of lithium dendrites, thereby enabling ultra-high-speed battery charging, which is expected to greatly extend the "life" of lithium batteries. The research results were published in the latest issue of "Advanced Materials".
