Lithiated Prussian blue analogues as positive electrode active materials for stable non-aqueous lithium-ion batteries

Abstract

Prussian blue analogues (PBAs) are appealing materials for aqueous Na- and K- ion batteries but are limited for non-aqueous Li-ion storage. Here, the authors report the synthesis of various lithiated PBAs and discuss critical factors for improving the non-aqueous electrochemical storage of Li ions.
