High‐Pressure‐Field Induced Synthesis of Ultrafine‐Sized High‐Entropy Compounds with Excellent Sodium‐Ion Storage

Angewandte Chemie International Edition, Journal Year: 2024, Volume and Issue: 63(27)

Published: April 23, 2024

Abstract Emerging high entropy compounds (HECs) have attracted huge attention in electrochemical energy‐related applications. The features of ultrafine size and carbon incorporation show great potential to boost the ion‐storage kinetics HECs. However, they are rarely reported because high‐temperature calcination tends result larger crystallites, phase separation, reduction. Herein, using NaCl self‐assembly template method, by introducing a high‐pressure field process, atom diffusion separation inhibited for general formation HECs, HEC aggregation is obtaining size. preparation ultrafine‐sized (<10 nm) HECs (nitrides, oxides, sulfides, phosphates) anchored on porous composites realized. They demonstrated combining advanced characterization technologies with theoretical computations. Ultrafine‐sized sulfides‐MnFeCoCuSnMo/porous (HES‐MnFeCoCuSnMo/PC) as representative anodes exhibit excellent sodium‐ion storage capacities (a rating capacity 278 mAh g −1 at 10 A full cell cycling 281 20 after 6000 cycles half cell) due advantages effect, size, PC incorporation.
