Do you know the development history of lithium battery?

In the early development of

The earliest application was in pacemakers. The self-discharge rate of the lithium battery is extremely low, and the discharge voltage is gentle. The device that is implanted in the human body can operate for a long time without recharging. Lithium batteries generally have a nominal voltage higher than 3.0 volts, making them more suitable for use as integrated circuit power supplies. Manganese dioxide batteries are widely used in calculators, digital cameras and watches. Various materials have been studied in order to develop more excellent varieties and create an unprecedented product.

Sony in 1992 successfully developed Lithium ion batteries. Its practical application, make people's mobile phone, notebook, calculator carry type electronic equipment such as less weight and volume.

The development process

1. In the 1970s, M.S. Whittingham of Exxon used titanium sulfide as the positive electrode material and lithium metal as the negative electrode material to make the first lithium battery.

2. In 1980, J. Goodenough discovered that lithium cobaltate can be used as a cathode material for lithium ion batteries.

3. R.R. Agarwal and J.R. Selman of the Illinois Institute of Technology in 1982 discovered that lithium ions have the property of being embedded in graphite. This process is rapid and reversible. At the same time, the lithium battery made of lithium metal has attracted much attention, so people tried to make a rechargeable battery by utilizing the characteristics of lithium ion embedded graphite. The first available lithium ion graphite electrode was successfully produced by Bell Labs.

4. In 1983, M. Thackeray and J. Goodenough discovered that manganese spinel is an excellent cathode material with low cost, stability and excellent conductivity and lithium guiding properties. The decomposition temperature is high, and the oxidation is much lower than that of lithium cobaltate. Even if short circuit or overcharge occurs, the risk of burning and explosion can be avoided.

5. In 1989, A. Manthiram and J. Goodenough discovered that a positive electrode with a polymeric anion would produce a 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 discovered that phosphates with olivine structure, such as lithium iron phosphate (LiFePO4), are superior to traditional cathode materials and have become the mainstream cathode materials.

With the widespread use of digital products such as mobile phones, notebook computers, etc., lithium-ion batteries are widely used in such products with excellent performance, and are gradually being developed into other product applications. In 1998, Tianjin Power Research Institute began commercial production of lithium-ion batteries. Habitually, people also call lithium-ion batteries lithium batteries, but these two batteries are not the same. Lithium-ion batteries have become a mainstream.

With the increasingly fierce competition in the lithium battery market, quickly and effectively grasping the market development has become the key to the success of corporate decision-making. In recent years, the scale and characteristics of various industry markets have undergone great changes. How to understand the development of the lithium battery industry and the market transformation from a professional perspective will become the primary problem for the future survival and development of enterprises.
