Porous carbon with carbon nanotube scaffold for embedding Cu2O/Cu nanoparticles towards high lithium storage

Abstract

Herein, it is demonstrated that the lithium storage performance of Cu2O electrode has been significantly upgraded by fabricating embedment of porous carbon (PC) with carbon nanotube (CNT) scaffold successfully. It is found that the combined effect of high conductive CNT and flexibly spongy porous carbon plays critical role in improving the electrochemical performance of Cu2O electrode for lithium-ion batteries, which efficiently upgrades not only the structural stability but also the conductivity of whole electrode. As a result, this Cu2O-based composite electrode shows outstanding cycling performance, high capacity and good rate capability, therefore exhibiting good promising for advanced lithium-ion battery anodes.
