U Akron team develops Mn-based high performance #anode for #Li-ion batteries

, where M is Mn, Co, Ni, Cu or Fe etc.) are promising anode candidate materials, owing to their high theoretical capacity and low cost. Among those materials, Mn3 O4 has been intensively investigated as one of the most promising anode materials due to its abundance, low oxidation potential and competitive electrochemical performance. However, several issues hamper the utilization of transition metal oxides as anode materials in LIBs: First, the poor intrinsic electrical conductivity of metal oxides limits the electron transfer throughout the electrode, leading to poor active materials utilization and low ratability. Second, the large volume expansion and shrinkage of the metal oxides during the lithiation and delithiation can result in electrode pulverization that promotes capacity fading during cycling. It has been well recognized that nano-engineering and carbon hybridiz...
