Spherical Templating of CoSe₂ Nanoparticle-Decorated MXenes for Lithium–Sulfur Batteries

Nano Letters, Journal Year: 2022, Volume and Issue: 22(21), P. 8679 - 8687

Published: Oct. 31, 2022

Two-dimensional MXenes produce competitive performances when incorporated into lithium-sulfur batteries (LSBs), solving key problems such as the poor electronic conductivity of sulfur and dissolution its polysulfide intermediates. However, MXene nanosheets are known to easily aggregate restack during electrode fabrication, filtration, or water removal, limiting their practical applicability. Furthermore, in complex electrocatalytic reactions like multistep reduction process LSBs, alone is insufficient ensure an optimal reaction pathway. In this work, we demonstrate for first time a loose templating spheres using Ti3C2Tx decorated with polymorphic CoSe2 nanoparticles. This work shows that nanoparticle-decorated can prevent nanosheet aggregation exert strong effect, thereby enabling improved kinetics battery performance. The S@MXene-CoSe2 cathode demonstrated long cycle life 1000 cycles low capacity decay rate 0.06% per LSBs.

Owing to its high volumetric capacity and natural abundance, magnesium (Mg) metal has attracted tremendous attention as an ideal anode material for rechargeable Mg batteries. Despite deposition playing integral role in determining the cycling lifespan, exact behavior is not clearly understood yet. Herein, first time, we introduce a facile approach build magnesiophilic In/MgIn sites situ on surface using InCl3 electrolyte additive These can regulate behaviors by homogenizing distributions of Mg-ion flux electric field at electrode-electrolyte interphase, allowing flat compact inhibit short-circuiting.
