The realisation of fast-charging lithium-ion batteries with long cycle lifetimes is hindered by the uncontrollable plating of metallic Li on the graphite anode during high-rate charging. Here we report that surface engineering of graphite with a cooperative biphasic MoO  x  –MoP  x   promoter improves the charging rate and suppresses Li plating without compromising energy density. We design and synthesise MoO  x  –MoP  x  /graphite via controllable and scalable surface engineering, i.e., the deposition of a MoO  x   nanolayer on the graphite surface, followed by vapour-induced partial phase transformation of MoO  x   to MoP  x  . A variety of analytical studies combined with thermodynamic calculations demonstrate that MoO  x   effectively mitigates the formation of resistive films on the graphite surface, while MoP  x   hosts Li +  at relatively high potentials via a fast intercalation reaction and plays a dominant role in lowering the Li +  adsorption energy. The MoO  x  –MoP  x  /graphite anode exhibits a fast-charging capability (<10 min charging for 80% of the capacity) and stable cycling performance without any signs of Li plating over 300 cycles when coupled with a LiNi 0.6 Co 0.2 Mn 0.2 O 2  cathode. Thus, the developed approach paves the way to the design of advanced anode materials for fast-charging Li-ion batteries.
