Hydrothermally Synthesized CoMn₂O₄/Graphite Composite as a High-Capacity Anode for Lithium-Ion Batteries
The increasing demand for high-energy-density lithium-ion batteries (LIBs) drives the development of anode materials with capacities exceeding that of graphite (372 mAh g⁻¹). CoMn₂O₄, with a high theoretical capacity (921 mAh g⁻¹), is a promising candidate but suffers from low conductivity and severe volume expansion....
