Analysis on the origin and development of lithium batteries

The Origin and Development of Lithium Batteries In the 1970s, Exxon’s M.S. Whittingham used titanium sulfide as the positive electrode material and metallic lithium as the negative electrode 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 batteries. In 982, R.R.Agarwal and J.R.Selman of the Illinois Institute of Technology (theIllinoisInsTItuteofTechnology) 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 usable 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. The analysis temperature is high, and the oxidation is much lower than that of lithium cobalt oxide. Even if there is a short circuit or overcharge, it can be guarded against the danger of combustion and explosion. In 1989, A. Manthiram and J. Goodenough discovered that a positive electrode with a polymer anion would have a higher voltage. In 1991, Sony announced the first commercial lithium battery. Subsequently, lithium 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 more superior than traditional cathode materials, and therefore have become the current mainstream cathode materials. Lithium batteries (Li-ionBatteries) are developed from lithium batteries. So before analyzing Li-ion, first analyze lithium batteries. For example, button batteries are lithium batteries. The cathode material of lithium batteries is manganese dioxide or thionyl chloride, and the anode is lithium. After the battery is packaged, the battery has voltage and does not need to be charged. This kind of battery can also be charged, but the cycle performance is not good. During the charging and discharging cycle, lithium dendrites are easily formed, causing internal short circuit of the battery. Therefore, this kind of battery is generally prohibited from charging. Later, Japan's Sony Corporation invented a lithium battery with carbon material as the negative electrode and lithium-containing compound as the positive electrode. During the charging and discharging process, there is no metal lithium, only lithium ions. This is a lithium battery. In the early 1990s, Sony Energy Development Corporation of Japan and Moli Energy Corporation of Canada successfully developed new types of lithium-ion batteries, which not only have good performance, but also have no pollution to the environment. With the rapid development of information technology, handheld machinery and electric vehicles, the demand for high-efficiency power supplies has risen sharply, and lithium batteries have become one of the fastest-growing categories.
