Functional cathodes with immobilized TEMPO(2,2,6,6-tetramethylpiperidinyloxyl) for Li–O2 batteries

Autor: Takuya Naruse, Norihiro Togasaki, Tetsuya Osaka, Toshiyuki Momma

Publikováno v: Journal of Power Sources Advances, Vol 24, Iss , Pp 100129- (2023)

Non-aqueous Li–O2 batteries offer an extremely high energy density, but suffer from high overvoltage on charge and poor cycle characteristics. In the past decade, soluble redox mediators (RMs) have been utilized to reduce the charge overvoltage. Ho
