Abstract: Thus far, the chemical co-precipitation has been most commonly adopted to synthesize (Nickel-Cobalt-Aluminum) NCA cathode materials specific for lithium-ion batteries (LIBs). However, co-precipitation of Ni2+, Co2+ and Al3+ is hard to control for their large difference in solubility product constant. To develop a new synthetic route of NCA, the fast solvothermal process-assisted high temperature solid-state reaction was firstly performed to synthesize well-constructed fine NCA cathode materials. The as-synthesized LiNi0.88Co0.09Al0.03O2 using a solvothermal method exhibits excellent high-temperature cycling performance. The study suggests that the fast solvothermal process-assisted high temperature solid-state method is a candidate for synthesizing the high-performance NCA cathode material.
