An advanced BiPO4/super P anode material for high-performance potassium-ion batteries

Abstract

Dispersed BiPO₄ nanoparticles loaded on the surface of a super P conducting network (BiPO₄/SP) were fabricated and investigated as a novel anode for PIBs. The BiPO₄/SP electrode demonstrates high rate capability (97.1 mA h g⁻¹ at 500 mA g⁻¹) and good long-term cycling performance (116 mA h g⁻¹ at 200 mA g⁻¹ over 100 cycles).
