Ultrafine Co-Doped NiO Nanoparticles Decorated on Carbon Nanotubes Improving the Electrochemical Performance and Cycling Stability of Li−CO₂ Batteries

Inspired by the concept of high nickel and low cobalt content in the electrode material, ultrafine Co_0.1Ni_0.9O_x nanoparticles decorated on carbon nanotubes (Co_0.1Ni_0.9O_x/CNT) are first developed in this work. Through various characterization techniques, the effects of doping Co²⁺ cations on the properties and electrochemical performance are systematically studied. The results enlighten new ideas of fabricating high-performance and cost-effective electrode materials for prolonging the cycling life of Li-CO₂ batteries toward practical applications
