Engineering In Situ Loose Selective Interface with Conducting Channels for Practical Ah-Level Aqueous Zinc Metal Batteries

A loose selective interface (LSI) is in situ constructed by self-assembly of porous organic cages for aqueous Zn metal batteries. The porous LSI enables fast Zn 2+ transport, dynamic self-repairing capability and dendrite-free Zn deposition. Ah-level aqueous Zn pouch cells deliver 1 Ah capacity with stable cycling performance.
