MnMoO 4 Sub‐Nano Sheets as Anode Materials for High‐Performance Lithium‐Ion Batteries

ABSTRACT Manganese molybdate (MnMoO 4 ) has emerged as a promising electrode material for high‐performance energy storage systems, owing to its high theoretical capacity and favourable electrochemical characteristics. Nevertheless, its practical application remains constrained by poor structural stability and a limited number of electroactive sites. To address these challenges, MnMoO 4 sub‐nano sheets (MnMoO 4 SNSs) are synthesized by the co‐assembly approach using Mn salts, phosphomolybdic acid (PMo 12 ), and oleylamine (OAm). Due to the high specific surface area, structural flexibility, adaptive properties, and electron delocalization of sub‐nano structures, the obtained MnMoO 4 SNSs deliver a high reversible specific capacity of 965 mAh g −1 at 0.18 A g −1 , and demonstrate remarkable cycling durability. This work presents an effective strategy for developing structurally stable sub‐nanometer MnMoO 4 electrodes and provides valuable insights for the rational design of next‐generation high‐energy‐density storage materials.
