A Large-Capacity, Superhigh-Rate Integrated Lithium Metal Anode with Top-Down Composition Gradient Enabled by Polyantimonic Acid

Interface engineering is an effective approach to solve the knotty Li-dendrite issues in lithium-metal batteries, and yet the robust large-capacity Li anode(>20 mAh cm−2) working at ultrahigh rate density(>20 mA cm−2) is still rarely...
