Co-Optimized Potassium Deposition and Interfacial Stability Enabled by 3D-Printed GO/ATP Hosts for Durable Dendrite-Free Potassium Metal Anodes.
Potassium metal batteries (PMBs) are promising candidates for next-generation large-scale energy storage owing to their high energy density and cost-effectiveness. However, their rate capability and cycling stability are severely hindered by sluggish K+ transport kinetics, uncontrolled dendrite growth, and fragile soli...
