Sn3O4 nanosheets with N-doped carbon coating for high performance lithium storage

Fabricating a high-performance anode by coating a carbon layer on a yolk–shell bimetallic selenide microsphere for enhanced lithium storage

“…Nitrogen doping can enhance the interaction between the carbon matrix and guest materials, thereby improving the electron transfer kinetics in CoSe 2 /Ni 3 Se 4 @NC composites. 36 Moreover, N-5 and N-6 facilitate the transfer of electrons from electron-rich nitrogen groups to Li + , leading to the formation of carbon defects that can enhance the number of active sites available for the storage of Li + . 37 Fig.…”
