摘要
As energy resource challenges intensify,lithium-ion batteries have gained prominence in research due to their eco-friendly nature,high energy density,long cycle life,and commercial viability[1].However,graphite development faces hurdles due to its low theoretical capacity,lithiation voltage closely approaching the Li+potential,and limited cycle life[2].Recent focus has shifted to binary transition metal oxides like Co2VO4,which offers advantages such as a safe Li+lithiation potential and high lithium-ion diffusion coefficient[3].Nonetheless,the intrinsic low electronic conductivity of metal oxides like CO_(2)VO_(4) presents a sig-nificant challenge,hindering its electrochemical kinetics and cycle sta-bility,thereby impeding practical implementation[4].
