dc.description.abstractCreating new architectures with a combined superiority of diverse materials achieving for more fantastic performances are attracting great attention recently. Herein, we introduce a novel dual metal (oxide) microsphere reinforced by vertically aligned carbon nanotubes (CNTs) and covered with a titanium oxide metal ion transfer diffusion layer. The CNTs penetrate the oxide particles and buffer structural volume change, while enhancing electrical conductivity. Meanwhile, the external TiO2-C shell serves as a transport pathway for mobile metal ions (e.g., Li+) and acts as a protective layer for the inner oxides by reducing the electrolyte/metal oxide interfacial area and minimizing side reactions. The proposed design is shown to significantly improve the stability and Coulombic efficiency (CE) of metal (oxide) anodes. For example, the as-prepared MnO-CNTs@TiO2-C microsphere demonstrates an extremely high capacity of 967 mAh g-1 after 200 cycles, where a CE as high as 99% is maintained. Even at a harsh rate of 5 A g-1 (ca. 5C), a capacity of 389 mAh g-1 can be maintained for thousands of cycles. The proposed oxide anode design was combined with nickel-rich cathode to make a full-cell battery that works at high voltage and exhibits impressive stability and life span.
