Controlled Nanoarchitecture of Aligned Electrospinning Fiber Composite Electrolyte Based on Plant and Animal Biopolymers for Safe Na‐Ion Batteries

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
Aligned Electrospun Composite Electrolyte. The resurgence of solid‐state Na+ battery, sustained through lithium deficiency and mounting costs, offers an auspicious alternative to solid‐state Li+ battery. This study introduces a nanoarchitectural approach that integrates electrospinning with a simple solution casting technique to develop a mechanically ...

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
