SK On Develops New Binder for Silicon Anode All-Solid-State Batteries
2026-01-15 23:39

SK On, in collaboration with a team from Yonsei University led by Professors Jung Yun-seok and Kim Jung-hoon, has developed a new material called 'PPMA' (an electronically conductive polymer) for use as a binder in silicon anodes. This material improves the structural stability of all-solid-state batteries by offering both conductivity and strong adhesion. SK On has successfully applied this new binder to silicon anode all-solid-state batteries, achieving stable operation under near-real-use conditions. The company is now accelerating its preparations for the mass production of all-solid-state batteries.
