The development of lithium ion batteries

The development of lithium ion batteries shared by  vacuum cleaner lithium ion battery manufacturer.

In the 1970s exxon's m.s. hittingham made the first lithium-ion batteries using titanium sulfide as a anode and lithium as a cathode.

In 1980, j. Goodenough discovered that lithium cobalt oxide could be used as a positive electrode for lithium-ion batteries.

In 1982 r.r. garwal and j.r. salman of the Illinois Institute of Technology found that lithium ions have the properties of being embedded in graphite, a process that is rapid and reversible. At the same time, lithium batteries made of lithium metal have drawn much attention to their safety risks. Therefore, people try to make rechargeable batteries by using the properties of lithium ion embedded in graphite. The first available lithium ion graphite electrode was trialled by bell LABS.

In 1983, m. hackeray and j. goodenough et al. found that manganese spinel was an excellent anode material with low price, stability and excellent electric and lithium conductivity. Its decomposition temperature is high, and oxidation is far lower than lithium cobalt oxide, even if there is a short circuit, overcharge, also can avoid the risk of combustion, explosion.

In 1989, a. a. thiram and j. g. guddenough found that using the positive electrode of the polymerized anions produced higher voltages.

1991 SONY corp. released the first commercial lithium-ion battery. Then lithium-ion batteries revolutionised consumer electronics.

In 1996, Padhi and Goodenough found that phosphate with olivine structure, such as lithium iron phosphate (LiFePO4), has more advantages than traditional anode materials, so it has become the mainstream anode materials.

With the wide use of digital products such as mobile phones and laptops, lithium ion batteries have been widely used in such products with excellent performance, and are gradually developing to other product application fields.

In 1998, tianjin power research institute began to produce lithium ion batteries commercially.

On July 15, 2018, a special carbon-negative material for high-capacity high-density lithium battery with pure carbon as the main component was released in the research institute of coal chemistry of keda. The lithium battery made of this new material can achieve a range of more than 600 kilometers.

In October 2018, the research group of professor liang jiajie and professor Chen yongsheng of nankai university cooperated with the research group of lai chao of jiangsu normal university to successfully prepare silver nanowires with multi-stage structure -- graphene 3d porous carrier and load lithium metal as composite negative electrode material. This carrier can inhibit the generation of lithium dendrites, so as to achieve ultra-high speed battery charging, which is expected to greatly extend the "life" of lithium batteries. The research is published in the latest issue of advanced materials.
