South Korea’s SK Innovation recently announced a collaboration with Professor John Goodenough, winner of the 2019 Nobel Prize in Chemistry and known as the “father of lithium-ion batteries,” according tomedia reports. The report says the new generation of battery technology not only has a higher energy density and better safety, but also has a more cost advantage. Lithium-ion batteries are known to be the most effective systems for electric vehicles. However, it has limitations in increasing energy density and it is almost impossible to reach 800Wh/L.
As a result, lithium metal anodes and solid electrolytes are considered a promising solution for batteries with a energy density of 1000Wh/L.
In addition to increasing energy density, the new battery technology is also effective in suppressing the production of lithium chimes. Lithium chidium is a branch-shaped metal lithium formed by lithium-ion reduction during the charging process, which affects the security and stability of the battery and is a major cause of the battery’s spontaneous combustion.
Dr Lee Seong jun, Chief Technology Officer of SK Innovation, said, “We are pleased to announce that SK Innovation and Professor Goodenough’s team are working together to prepare for the next generation of battery age. This will be a meaningful step in the company’s journey to provide safe and cost-competitive and innovative lithium metal batteries. “
There is no timetable for when the solid-state battery will be commercialized. We will continue to pay attention.
