Improvement in rate capability of lithium-rich cathode material Li[Li0.2Ni0.13Co0.13Mn0.54]O2 by Mo substitution
Lithium-rich cathode material Li[Li 0.2 Ni 0.13 Co 0.13 Mn 0.54 ]O 2 doped with trace Mo is successfully synthesized by a sol-gel method. The X-ray diffraction patterns show that trace Mo substitution increases the inter-layer space of the material, of which is benefiting to lithium ion insertion/ex...
