Anode of Anthracite Hard Carbon Hybridized by Phenolic Epoxy Resin toward Enhanced Performance for Sodium-Ion Batteries

ACS Applied Energy Materials, Journal Year: 2024, Volume and Issue: 7(15), P. 6704 - 6716

Anthracite-based carbon is considered one of the most promising anodes for sodium-ion batteries (SIBs) due to its abundant natural resource and low cost. However, their performance very poor. In this article, microstructure anthracite hybridized by phenolic epoxy resin. The cross-linking reaction between resin generates hybrid carbon. structure transforms from graphite-like phase pseudographite phase, accompanied increase interlayer spacing. Due formation oxygen-containing functional groups, defects are generated on surface inside. Phenolic a microhard around anthracite, in which curved intertwined disordered formed. This can effectively reduce degree graphitization promote rearrangement, inhibit regular accumulation layers. anode with 5% pyrolyzed at 1200 °C improved obviously, delivering capacity 357.7 mAh g–1 current density 50 mA excellent retention 89% after 500 cycles g–1. According situ Raman analysis, it be seen that Na+ mainly adsorbed defect sites open pore gaps material then inserted pseudographitic region. research proposes an effective strategy enhance coal material, providing huge opportunity commercialization low-cost SIBs.
