Theoretical specific capacity
Webb20 juni 2024 · It has also been demonstrated that carbon nanohorns (CNHs) possess good electric conductivity and a large surface area and acted as a carrier for MnO 2 nanosheets; the composite showed a reversible discharge capacity of 565 mAh g −1 as tested at a 0.1-C current rate (1 C = 1000 mA g −1) after 60 charge/discharge cycles [ 19 ]. WebbFurthermore, the electrochemical performances of batteries using the modified cathode material are evaluated. The first discharge specific capacity is measured at 202.6mAh g-1 under a 25mA g-1 current density and an 85.9% capacity retention rate under 254mA g-1 current density after 200 cycles.
