SK Innovation announced on Feb. 19 that it signed an agreement with Poly Plus Battery Co., a U.S. battery technology development company, to co-develop lithium metal batteries.
SK Innovation will invest in research and development of conductive glass separators owned by Poly Plus. The company said it was considering making an equity investment in Poly Plus and licensing its technology in the future.
SK Innovation plans to complete research on conductive glass separators by the end of 2021 and apply them to the development of lithium metal batteries.
Conductive glass separators are a key technology for stabilizing lithium metal batteries. The company hopes that a successful development of conductive glass separators would accelerate commercialization of lithium metal batteries.
The deal also marked the first case of acquiring a new technology through the open innovation approach launched by the SK Innovation Technology Innovation Center last year.
