The 2019 Nobel Prize in Chemistry was awarded to John Goodinuff of the University of Texas at Austin, Stanley Wittingham of the State University of New York at Bingham, and Akira Yoshino of Asahi Kasei Corporation in recognition of their Outstanding contribution to the development of lithium-ion batteries. So, how was lithium battery developed? What will happen in the future?
There is no mobile smart life without lithium battery
We have already lived in a "rechargeable world", but it is lithium batteries that have really brought about the portability of electronic devices and opened the modern mobile life. It can be said that if there is no lithium battery, there will be no mobile intelligent life we have now.
Lithium batteries are widely used in various fields from mobile phones to notebook computers due to their light weight, rechargeable, powerful and portable. It is used worldwide to power portable electronic devices that we use to communicate, work, learn and play.
Lithium batteries have also promoted the development of long-lasting electric vehicles and energy storage from renewable energy sources such as solar and wind energy, laying the foundation stone for a wireless (mobile), fossil-free society. It can be said that lithium-ion batteries, as energy storage devices, have completely changed human life.
The Nobel Prize in Chemistry was awarded to three scientists in the field of lithium battery. It is a recognition for each lithium battery practitioner who has contributed to the lithium battery from scratch and has gone from the laboratory to commercialization. He Zhi continues to inspire people in the development of a clean and portable society.
The oil crisis led directly to the development of lithium batteriesIn the 1970s, the oil crisis led directly to the development of lithium batteries.Exxon, an American oil giant, has formed a team to develop the next generation of alternative energy technologies for fossil fuels, judging that oil, a typically non-renewable resource, will soon run out.Lithium battery is one of the new batteries.At the time, Stanley whittingham of exxon proposed a new material, titanium disulfide, as a cathode that could store lithium ions between molecular layers.When matched with the lithium metal cathode, the battery voltage is as high as 2V.However, lithium metal batteries have not been popularized because of their high negative activity, which poses great safety risks.But scientists have not given up their quest, and since the problem is the electrode material, perhaps replacing the electrode will solve the problem.Gudinoff, then director of the inorganic chemistry laboratory at the university of Oxford in England, reasoned that using metal oxides instead of sulfides as the positive electrode could lead to higher voltages and improved lithium-ion battery performance.In 1980, gudinoff used lithium cobalt oxide as the positive terminal, which raised the battery's voltage to 4V.Lithium cobalt oxide is a great breakthrough in the field of lithium ion batteries.
Lithium batteries have a lot of room to growThis year's Nobel Prize in chemistry for lithium batteries is a great affirmation and inspiration to the industry.From birth and development to application and promotion, lithium battery is still facing many formidable challenges.Ever since SONY commercialized the first lithium-ion batteries in 1991, the "rocking chair" with the lithium ions that come and go has been the most promising and fastest-growing market.But limited by the principle of lithium-ion batteries, the energy density of the existing system has fallen from an annual growth rate of 7% to 2% and is approaching its theoretical limit.On the contrary, with the progress of society, people have a stronger need for portable and clean life.
China's lithium battery researchers are carrying out a lot of original workChina, Japan, South Korea, Germany, Britain and other countries have formulated their own battery development strategies, with a view to promoting the innovation of battery principles and the development of core technologies to support the sustainable development of contemporary society.With the support of the state and society, lithium battery researchers in China continue to carry out scientific research on the basis of efficient energy storage.
In addition to lithium batteries, the use of sodium, potassium, aluminum and zinc plasma and the development of new principles of energy chemistry, is also expected to put forward unique new energy storage devices.In addition to electrochemical energy storage, the adoption of other energy storage and transformation methods and new energy carriers is expected to build a subversive energy storage technology to meet the future society's new demand for energy storage equipment.Breakthroughs in the next generation of energy storage and conversion technologies are on the way.
