Jiwei Network News, SK Innovation announced today (16) that it will cooperate with Professor Seung-woo Lee of the Georgia Institute of Technology in the United States to develop the next generation of all-solid-state batteries.

According to Yonhap News Agency, all-solid batteries are batteries that convert liquid electrolytes into solids, which can reduce the weight and volume of batteries while increasing battery capacity, so they are evaluated as "future batteries". But there are many difficulties in the development process, also known as "dream batteries".

SK Innovation said that the partnership with Professor Lee's team in the field of all-solid-state batteries can become a game-changer in the electric vehicle market.

It is understood that Professor Lee and the Korea Advanced Institute of Science and Technology (KAIST) jointly developed an innovative rubber form of polymer solid electrolyte, the paper was published in the world academic journal Nature, and is known as a university in the field of related fields.

The solid electrolyte developed by Professor Lee increases the ionic conductivity by a factor of 100 while ensuring the rubbery elasticity of the battery.

SK Innovation explains, "The increased ion conductivity allows the lithium ions inside the battery to be quickly communicated, thereby improving battery performance, and ensuring safety if the solid electrolyte has excellent elasticity, as the electrolyte is not damaged by 'Dendrite'." ”

The person in charge of SK Innovation said: "Previously, solid electrolytes were considered a difficult task to ensure both ion conductivity and safety, so Professor Lee's invention was called an innovative research result. ”

SK Innovation predicts that if the technology is introduced, the current range of electric vehicles of about 500 kilometers will increase to 800 kilometers.
