Lithium manganese oxide, LiMn 2 O 4 (LMO) is a promising cathode material, but is hampered by significant capacity fade due to instability of the electrode-electrolyte interface, manganese dissolution into the electrolyte and subsequent mechanical degradation of the electrode.
In contrast to conventional layered positive electrode oxides, such as LiCoO 2, relying solely on transition metal (TM) redox activity, Li-rich layered oxides have emerged as promising positive electrode materials due to their utilization of both TM and oxygen redox at high voltage, resulting in an improved discharge capacity 1.
Mesoporous Mn 2 O 3 prepared via chemical co-precipitation and modified with reduced graphene oxide was used as electrode materials in a lithium-ion battery. The Mn 2 O 3 had a charge and discharge of 771.3 and 1167.6 mAh g −1 capacity and maintained only 66% Coulombic efficiency.
Manganese (III) oxide (Mn 2 O 3) has not been extensively explored as electrode material despite a high theoretical specific capacity value of 1018 mAh/g and multivalent cations: Mn 3+ and Mn 4+. Here, we review Mn 2 O 3 strategic design, construction, morphology, and the integration with conductive species for energy storage applications.
This review summarized the developments related to the effective use of Mn 2 O 3 as an efficient electrode material for energy storage applications. The performance of Mn 2 O 3 and composite electrodes improved due to various modifications such as morphological optimization, which increased the electrodes’ porosity and surface area.
