Transition metal sulfides are deemed as attractive anode materials for potassium-ion batteries (KIBs) due to their high theoretical capacities based on conversion and alloying reaction. However, the main challenges low electronic conductivity, huge volume expansion, consequent formation of unstable solid electrolyte interphase (SEI) upon potassiation/depotassiation. Herein, zinc sulfide dendrites deeply nested in tertiary hierarchical structure through a solvothermal-pyrolysis process...

Solid electrolyte interphases (SEIs) are sought to protect high-capacity anodes, which suffer from severe volume changes and fast degradations. The previously proposed effective SEIs were of high strength yet abhesive, inducing a yolk–shell structure decouple the rigid SEI anode for accommodating change. Ambivalently, interfacial void-evolved electro-chemo-mechanical vulnerabilities become inherent defects. Here, we establish new rationale that resilience adhesivity both requirements pioneer...
