(a) The second-cycle discharge voltage profiles of LiMn₂O₄/graphene (I_LMO:G = 1.22) between 2 and 4.5 V at 1.27 C. (b) Rate response of commercial LiMn₂O₄ and LiMn₂O₄/graphene (I_LMO:G = 1.22) between 2 and 4.5 V. All samples were cycled at the same discharge/charge current densities. (c) Discharge voltage profiles of LiMn₂O₄/graphene (I_LMO:G = 1.22) between 2 and 4.5 V. (d) Cycling performance of LiMn₂O₄/graphene (I_LMO:G = 1.22) at 5625 mA·g⁻¹ (38.01 C) discharge current and 2812 mA·g⁻¹ (19.00 C) charge current.
