Engineering Nanoclay Edges to Construct Effective Polysulfide‐Trapping Interface for Markedly Enhanced Electrochemical Energy Storage

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
A capsule‐shaped silicate clay (H‐ATP‐N2) rich in protonated edge hydroxyl groups (‐OH2+) is synthesized through a two‐step process involving microwave‐assisted acid treatment and N2 plasma etching to fibrous natural attapulgite. The H‐ATP‐N2 host inhibits the shuttle effect owing to the dominant adsorption mechanism–Lewis acid–base interaction between
