摘要
Here,we present a regulation strategy involving heteroatom doping and structural construction to adjust zincophilic sites and electric field distribution,achieving a robust and dendrite-free Zn host anode.Theoretical calculations and experimental results confirm that sulfur atoms can provide moderate zincophilicity,while graphene-like nanosheets can even the electric field distribution,imparting the sulfurdoped graphene-like network(S-GP) with a longer lifespan(exceeding 500 h) and acceptable coulombic efficiency.Importantly,the S-GP host is used as the substrate for flexible Zn-ion batteries,exhibiting impressive electrochemical performance and great mechanical flexibility,indicating a broad application prospect in portable and wearable electronic devices.
