Fabrication of CNTs/MnO 2 composite as a wrapping layer for surface modification of Cr-doped LiNi 0.5 Mn 1.5 O 4 for lithium ion batteries
Needle-like MnO 2 is deposited on the surface of CNTs using a simple redox reaction and simultaneously forms a special wrapping layer on the surface and among the particles of Cr-doped LiNi 0.5 Mn 1.5 O 4 through an auto-grow process. The CNTs act as a conductive network of electrons and the needle-...
