Abstract:In this paper, Ni-rich Co-free cathode materials, LiNi0.94Mn0.04Al0.02O2 (NMA),
were synthesized
by a solid-phase sintering process. The effects of different lithium
ratios on the morphology, structure, and electrochemical performance
of NMA cathode materials were investigated. The experiments show that
NMA-1.03 has the smallest Li+/Ni2+ mixing and
the best crystal structure. The electrochemical performance analysis
showed that the initial discharge specific capacity of NMA-1.03 was
199.5 mAh g–1 at 1C, and th… Show more
