Porous carbon-confined Co_xS_y nanoparticles derived from ZIF-67 for boosting lithium-ion storage

Abstract

A composite of CoxSy and carbon shell is successfully formed, and as a result it can well alleviate volume change as well as offer sufficient ions/electrons transfer channels, contributing to enhance electrochemical performance.

Recent Progress in MOF‐Derived Porous Materials as Electrodes for High‐Performance Lithium‐Ion Batteries

“…Su's group used ZIF‐67 as raw material and template, then synthesized Co x S y composites with carbon shells by hydrothermal vulcanization subsequent to a high‐temperature sintering process. [ 186 ] Furthermore, at a current density of 500 mA g −1 , the Co x S y ‐700°C electrode retained 88% of its capacity after 1000 cycles and demonstrated an exceptional rate capability of 526.5 mAh g −1 . Up to now, there have been few reports on NiS 2 used as LIBs anode material, TMSs electrodes previously derived from Ni‐MOF had been confirmed to undergo the conversion reaction during charging and discharging.…”

Fabrication of well-aligned Co-MOF arrays through a controlled and moderate process for the development of a flexible tetrabromobisphenol A sensor

“…41 Composites of conductive MOFs with carbon materials can greatly improve electrical performance while maintaining and amplifying other mechanical, thermal, and chemical properties. [42][43][44] In recent years, the combination of MOFs and flexible sensors as electrochemical sensors has attracted great interest.…”
