【Li-battery common sense】battery History
In the 1970 s, exxon's M.S.W hittingham using titanium sulfide as the anode material, metallic lithium as negative material, made the first lithium battery.
In 1980, Wallace Yazami et al in Grenoble, institute of technology (INPG) and France's national centre for scientific research (CNRS) found embedded lithium ion has the characteristics of graphite.This process is rapid and reversible.Their results, published in 1982 and 1983.It covers the thermodynamics (staging) and dynamics (diffusion) together with the reversibility.
At the same time, made of metallic lithium lithium batteries, much attention has been paid to its safety problems, so people try to take advantage of the characteristics of lithium ion embedded graphite production of rechargeable batteries.First available lithium ion graphite electrode successfully trial-produced by bell LABS in 1981.
In 1991, SONY has released the first commercial lithium-ion battery, battery USES the layered oxide.Subsequently, lithium ion batteries have revolutionized the face of consumer electronics products.
1983 m. hackeray, J.G galaxite oodenough and others found to be excellent cathode material, with a low price, stable and good conductive lithium, guide performance.Its decomposition temperature is high, and oxidation is far lower than the cobalt acid lithium, even if a short circuit, over charge, also can avoid the risk of combustion and explosion.Although pure galaxite loop attenuation, materials chemistry modified can overcome this weakness.Galaxite currently used in batteries for commercial use.
In 1989, the university of Texas at Austin arjun anthiram and J.G oodenough found due to the inductive effect of anionic polymerization, using anionic polymerization of positive, such as sulfate, will produce a higher voltage than oxide.
Padhi and Goodenough found 1996 has olivine structure of phosphate, such as lithium iron phosphate (LiFePO4), than the traditional anode material in safety and life has improved, but the low temperature performance and compaction density remains to be improved.In 2002, yet-ming Chiang and his team at the Massachusetts institute of technology developed by aluminium, niobium, zirconium and other three kinds of metal anode super lithium batteries, increase the electrical conductivity of the material, significantly improve the performance of lithium-ion batteries.The principle of the exact caused a heated debate at that time.
In 2004, yet-ming Chiang again with diameter less than 100 nanometers iron phosphate particles improve the battery performance.This reduces the particle density of nearly one hundred times, so as to improve the surface area of the cathode, and enhance the capacity and performance of the battery.Commercial lead to intense market competition, triggering yet-ming Chiang and goody, a patent dispute between.
