Development Of Lithium Battery

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

2. In 1980, J. goodenough discovered that lithium cobalt oxide can be used as a cathode material for lithium-ion batteries.

3. In 1982, r.r.agarwal and j.r.selman of the Illinois Institute of technology found that lithium ion has the characteristic of intercalation into graphite, which is fast and reversible. At the same time, lithium batteries made of metal lithium have attracted more and more attention. Therefore, people try to make rechargeable batteries by using the characteristics of lithium ion embedded in graphite. The first available lithium-ion graphite electrode was successfully developed 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 much lower than that of lithium cobalt oxide. Even if there is short circuit and overcharge, the danger of combustion and explosion can be avoided.

5. In 1989, a. manthiram and J. goodenough found that the positive electrode with polyanion produced higher voltage.

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

7. In 1996, padhi and goodenough found that phosphate with olivine structure, such as LiFePO4, has more advantages than traditional cathode materials, so it has become the mainstream cathode materials.

With the wide use of digital products such as mobile phones, laptops and other products, lithium-ion batteries are widely used in such products with excellent performance, and gradually develop to other product application fields. In 1998, Tianjin Power Research Institute began to produce lithium-ion batteries commercially. Traditionally, people call lithium-ion batteries lithium-ion batteries, but the two batteries are not the same. Lithium ion batteries have become the mainstream.
