MnMoO₄ Sub-Nano Sheets as Anode Materials for High-Performance Lithium-Ion Batteries

Manganese molybdate (MnMoO₄) 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, MnMoO₄ sub-nano sheets (MnMoO₄ SNSs) are synthesized by the co-assembly approach using Mn salts, phosphomolybdic acid (PMo₁₂), and oleylamine (OAm). Due to the high specific surface area, structural flexibility, adaptive properties, and electron delocalization of sub-nano structures, the obtained MnMoO₄ 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 MnMoO₄ electrodes and provides valuable insights for the rational design of next-generation high-energy-density storage materials.
