碳微管纤维布负载ReS2用于钠离子电池低成本负极
Carbonmicrotube fiber cloth-supported ReS2 as a low-cost anode for sodium-ion batteries
摘要
Abstract
Self-supported carbon cloth electrodes show great potential in the developing low-cost sodium-ion batteries(SIBs).Rhenium disulfide(ReS2),with its high theoretical capacity,has attracted much attention.However,its low electrical conductivity severely affects the electrochemical performance.To address this challenge,a low-cost carbon microtube(CMT)fiber cloth was designed to replace the traditional metal current collectors(copper/aluminum foils),and a hydrothermal self-assembly process was utilized to in-situ construct a composite structure of ReS2 nanospheres on the CMT surface(CMT@ReS2@C).The rapid electron transport was facilitated by 3D conductive network in the CMT fiber cloth,while the electrolyte infiltration was enhanced by its porous structure.Furthermore,the structural volume expansion during repeated charge/discharge cycles was effectively mitigated by the synergistic interaction between ReS2 and the carbon microtube fiber cloth.Benefiting from these advantages,the CMT@ReS2@C anode demonstrates superior electrochemical performance in SIBs.Specifically,it retains a reversible capacity of 94 mAh·g-1 after 500 cycles at 1 A·g-1,with an average capacity decay rate of only 0.081％per cycle.关键词
