Abstract：The performance degradation of silicon anodes caused by volume expansion during lithium storage is closely associated with the limited mechanical strength and conductivity of conventional binders and conductive additives.To address this challenge,we employ aramid-modified Ti3C2Tx MXene as a novel multifunctional binder for silicon-based anodes.This novel binder,combining high electrical conductivity with excellent mechanical strength,effectively mitigates stress during lithiation/delithiation,prevents large-scale electrode cracking,and thereby significantly enhances the cycling stability(maintaining 1 127 mA•h/g after 100 cycles at 0.2 A/g)and rate capability(maintaining 927.8 mA•h/g at 2 A/g)of the silicon anode.This design strategy for an aramid-modified Ti3C2Tx MXene binder offers a novel approach to enhancing the performance of lithium-ion batteries and other energy storage materials.
