A cooperative biphasic MoO x –MoP x promoter enables a fast-charging lithium-ion battery

Abstract

Fast-charging of lithium-ion batteries is hindered by the uncontrollable plating of metallic Li on the graphite anode during cycling. Here, the authors demonstrate the fast chargeability and long cycle lifetimes via surface engineering of graphite with a cooperative biphasic MoO x –MoP x promoter.
