Abstract
A carbonate precursor that has a high-nickel and low-cobalt sandwich structure, a preparation method therefor and an application thereof. The precursor includes an inner core and an outer shell layer, wherein the outer shell layer covers at least a part of the outer surface of the inner core. The carbonate precursor having the sandwich structure has the advantages of narrow particle size distribution, good fluidity, and an excellent electrochemical performance, and may be stably produced in both an ammonia-free system and an ammonia-containing system.
