Facile solid-state synthesis of a layered Co-free, Ni-rich cathode material for all-solid-state batteries†
Abstract
Layered Ni-rich oxides are attractive cathode active materials for secondary battery applications. Combining them with inorganic superionic conductors and high-capacity anodes can significantly increase energy density. Herein we successfully synthesized spherical secondary particles of a Mn-substituted LiNiO2, LiNi0.95Mn0.05O2 (a Co-free NMX material), for use in bulk-type lithium-thiophosphate-based all-solid-state batteries.
