Development Process Of Lithium Batteries

In 1970, M.S. Whittingham, who replaced Exxon, made the first lithium battery using titanium sulfide as the positive electrode material and lithium metal as the negative electrode material.
In 1980, J Goodnough 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 property of embedding into graphite, a process that is fast and reversible. At the same time, the safety hazards of lithium batteries made of metallic lithium have attracted much attention. Therefore, people have tried to use the characteristics of lithium ions embedded in graphite to make rechargeable batteries. 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 cost, stability, and excellent conductivity and lithium conductivity. Its decomposition temperature is high, and its oxidizability is far lower than that of lithium cobalt oxide. Even in the event of short circuit and overcharging, it can avoid the danger of combustion and explosion.
In 1989, A. Manthiram and J. Goodnough discovered that using a polyanion positive electrode would produce a higher voltage.
In 1991, Sony released its first commercial lithium-ion battery. Subsequently, lithium ion batteries revolutionized the face of consumer electronics.
In 1996, Padhi and Goodnough discovered that phosphates with olivine structures, such as lithium iron phosphate (LiFePO4), have more advantages than traditional cathode materials, and have become the current mainstream cathode materials.
With the widespread use of digital products such as mobile phones, laptops, and other products, lithium ion batteries have been widely used in these 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 Kodak Coal Chemistry Research Institute that a special carbon negative electrode material for high capacity and high density lithium batteries, mainly composed of pure carbon, was introduced in the institute. This lithium battery made of entirely new materials can achieve a vehicle mileage of over 600 kilometers. [1]
In October 2018, the research team of professors Liang Jiajie and Chen Yongsheng from Nankai University and Lai Chao from Jiangsu Normal University successfully prepared a silver nanowire graphene three-dimensional porous carrier with a multi-level structure, and loaded with metal lithium as a composite negative electrode material. This carrier can inhibit the generation of lithium dendrites, thereby achieving ultra-high speed battery charging, and is expected to significantly extend the "life" of lithium batteries. The research results were published in the latest issue of Advanced Materials [2].
In the first half of 2022, the main indicators of China's lithium ion battery industry achieved rapid growth, with output exceeding 280 GWh, a year-on-year increase of 150% [4]
On the morning of September 22, 2022, the cathode roller, the first new energy lithium copper foil core equipment in China with a diameter of 3.0 meters independently developed by the Fourth Academy of China Aerospace Science and Technology Group and qualified for delivery to users, was launched in Xi'an, filling the technical gap in the domestic industry, achieving a monthly production capacity of large diameter cathode rollers that exceeded 100 units, marking a significant breakthrough in China's manufacturing technology of large diameter cathode rollers
