The 2019 Nobel Prize in Chemistry are awarded to John Goodenough, M. Stanley Whittingham and Akira Yoshino “for the development of lithium-ion batteries”.
Through their work, they have created the right conditions for a wireless and fossil fuel-free society, and so brought the greatest benefit to humankind.
Lithium batteries have penetrated into every aspect of our daily lives, and winning the prize in this field is also expected.
The development of human society is inseparable from energy. The development of several industrial revolutions relies on the development of energy storage technology. Today, lithium-ion batteries provide electricity to the world, from smartphones to electric vehicles. Lithium-ion batteries are ubiquitous, paving the way for an increasingly mobile world. Compared with other commercial rechargeable batteries, lithium-ion batteries have become an important research direction for scientists in various countries due to their high energy density, long cycle life, wide operating temperature range and safety and reliability.
Another important cathode material, lithium iron phosphate (LiFePO4), is also one of his important contributions. In 1997, a research group guided by Goodenough reported the reversible migration of lithium iron phosphate into lithium. Lithium iron phosphate is currently the safest lithium ion battery cathode material and does not contain any heavy metal elements harmful to human body. As the inventor of positive electrode materials such as lithium cobaltate and lithium iron phosphate, Goodenough is well-known in the field of lithium-ion batteries, and is a veritable "father of lithium-ion batteries."
This major research result lays a solid foundation for the subsequent application of lithium iron phosphate battery in communication standby, UPS field and energy storage application.
At present, Sacred Sun has successfully applied in lithium iron phosphate battery products in operator base stations, data center and intelligent integrated ESS for residential off-grid applications.
