Abstract
A layer-by-layer (LBL) structure composed of Co3O4 nanoplates and capillary-like three-dimensional (3D) multiwall carbon nanotube (MWCNT) nets was developed as an anode with simultaneous high-rate and long-term cycling performance, in a lithium-ion battery. As the current density was increased to 50 A g(-1), the LBL structure exhibited excellent long-term cycling and rate performance. Thug, the Co3O4 nanoplates were in good electrical contact with the capillary-like 3D MWCNT net under Mechanically severe strain during long-term, high-rate cyclic operation.
