Synthesis of macroporous carbon materials as anode material for high-performance lithium-ion batteries

In this paper, a type of macroporous carbon (MPC) material was produced using water-soluble sodium carbonate (Na₂CO₃) as the template and glucose as the carbon precursor. After annealing in an argon atmosphere (Ar) at 700 °C, the samples exhibited specific surface areas up to 600 m² g⁻¹ with different proportions of sodium carbonate and glucose. When the samples were employed as anode materials in lithium-ion batteries, the electrodes delivered a stable reversible capacity at 200 mA g⁻¹ and favourable cycling stability at 500 mA g⁻¹. Moreover, all MPC samples exhibited excellent rate performances at 5000 mA g⁻¹.
