Abstract

Abstract

En 中文
• A dual-protection strategy suppresses polyselenide shuttling and volume expansion for stable Al batteries. • Cu2Se/CoSe2 heterointerfaces accelerate redox kinetics and optimize electronic structure for Al storage. • Hollow carbon nanotubes buffer mechanical strain and confine active species during cycling. • Achieving 274.2 mAh g−1 over 1000 cycles and high-rate performance up to 3.2 A g−1.
