What is it about?
the Co4+-TiO2@C nanocomposites with hierarchical structure can be simply derived from Co(II)(OH)n@Ti3C2 by thermally annealing, which shows the highest reversible capacity (154.7 mAh g-1 at 0.1 A g-1 after 200 cycles) and extraordinary rate performance in HMLBs

Why is it important?
The hierarchical nanocomposites can simply be prepared by Ti3C2 MXene. Its excellent electrochemical performance and Li+ diffusion kinetic are attributed to the synergistic effect of the hierarchical structure and cobalt-doping, effectively improving the electronic conductivity and ionic diffusion rate .
Perspectives
Thermally annealing M(II)(OH)n@Ti3C2 is a simple and efficient method for preparing metal-doped TiO2@C hierarchical nanocomposite. This work provides a new insight into designing TiO2-based cathode materials with high performance in HMLBs
