The inventor of the lithium battery won the Nobel Prize in chemistry! A brief history of lithium battery development (worth collecting)

On the morning of October 9, local time, the Royal Swedish Academy of Sciences announced in Stockholm that it would award the 2019 Nobel Prize in Chemistry to American scientist John B. Goodinave, British scientist M. Stanley Wittingham and Japanese scientist Akira Yoshino for their contribution to the "development of lithium-ion batteries. They will share a bonus of 9 million Swedish kronor (about 6.5 million yuan).

John B. Gudinav is the father of lithium batteries. He made lithium batteries smaller, larger and more stable in use, thus realizing commercialization and opening the process of portability of electronic devices. At present, he is a professor of mechanical engineering at the University of Texas at Austin. At the age of 97, he is a famous solid state physicist, the inventor of lithium cobalt oxide, lithium manganate and lithium iron phosphate cathode materials, and one of the founders of lithium ion batteries. He designs new materials and solves material science problems by studying the relationship between chemistry, structure and solid electronic/ionic properties. Sony produced the world's first commercial lithium battery after adopting the Goodenave theory in 1991. Since then, mobile phones, cameras, handheld cameras and even electric vehicles have entered the era of portable new energy.

M. Stanley Witingham used the huge power of lithium to release its external electrons when developing the first functional lithium battery in the early 1970 s. He is currently the Director of the Materials Research Institute and the Department of Materials Science and Engineering at Binghamton University, State University of New York.

Akira Yoshino is the inventor of modern lithium-ion batteries and has won the Global Energy Award and the Charles Stark Draper Award, the highest honor in engineering. He is currently a researcher at Asahi Kasei and a professor at Mingcheng University.

Lithium-ion batteries have revolutionized our lives and are used in all applications from mobile phones to laptops and electric cars. It can be said that lithium-ion batteries make many ordinary people can only look up to the technology, fly into the homes of ordinary people. Next, let's take a look at the development history of lithium batteries. A brief history of

lithium battery

in the 1960 s, the world under the shadow of the cold war was filled with tense air. during the oil crisis, countries were directly forced to find new alternative energy sources. at the same time, due to the continuous escalation of the arms race, the batteries at that time could no longer meet the needs of high energy density power sources. Therefore, the lithium battery that can theoretically obtain the maximum energy density has naturally entered the field of vision of battery designers.

Throughout the history of lithium battery development, it is not difficult to find that in the development of lithium battery technology, has always been dominated by the United States and Japan, so how is the development of lithium batteries in China?

Lithium battery China speed

Due to its late start, so in the era of lithium primary batteries, China's battery industry has long been monopolized by foreign capital. Since the early 1980 s, the research and development of lithium-ion batteries has only begun. In 2000, Japan's annual output of lithium-ion batteries reached 0.5 billion, accounting for more than 90% of the global market, while China's annual output was only 0.035 billion. With the development of technology, in order to meet the needs of social development, China has issued a series of policies to promote the development of lithium-ion battery industry: in the outline of the national medium and long-term science and technology development plan (2006-2020), power lithium-ion battery is listed as the priority development direction of high-efficiency source material technology. With the support of a series of national policies, China's lithium-ion battery industry has entered a stage of rapid growth.

Shenzhen BYD, Shenzhen Bick, Tianjin Lishen and other lithium-ion battery enterprises have risen rapidly. In 2004, China's annual output of lithium-ion batteries reached 0.8 billion, with its global market share soaring to 38%, second only to Japan. According to data from the National Bureau of Statistics, by 2013, my country's annual output of lithium-ion batteries has reached nearly 4.768 billion, and it has developed into a global battery manufacturing country. In 2015, China has surpassed South Korea to become the largest producer of lithium-ion batteries. In 2019, China has accounted for 73% of the world's total lithium battery production capacity.

At the same time, technological breakthroughs have greatly expanded the scope of application of lithium batteries.

In the field of electric vehicles, Wanxiang Group provided lithium-ion batteries for electric vehicles and hybrid vehicles for the Shanghai World Expo; in addition to continuous in-depth cooperation with BYD and Shanghai Space Power Research Institute, SAIC Motor also cooperated with the global lithium secondary The US A123, which is a technology leader in the battery field, has established a joint venture company to produce and sell automotive power battery systems.

In the field of power grid energy storage technology, in February 2011, my country's first megawatt-level battery energy storage power station-China Southern Power Grid 5MW battery energy storage power station was successfully connected to the grid in Shenzhen. The total capacity of the battery energy storage power station is 10MW, After all put into production, it will become the world's largest lithium-ion battery energy storage power station.

In the field of aerospace, the specific energy of circular lithium-ion batteries for domestic space is currently about 110 ~ 140Wh/kg; in terms of battery ground life test, high-orbit satellites have 80% DOD, reaching a 15-year life level; low-orbit satellites have 30% DOD, reaching a 5-year life level.

From the 2019 Nobel Prize in Chemistry, it can be seen that the world is now paying attention to energy storage technology represented by batteries. Indeed, in the context of the energy revolution, it is important to find new sources of energy, and it is equally important to store these sources of energy. At the same time, China's battery industry continues to amaze the world with the efforts of scientific researchers, hoping that China can maintain this momentum and become a real energy storage power!
