- A novel type surface modified activated carbon (AC) was prepared using the electroless deposition method
as a new attempt to modify AC for Li-ion capacitors. The resulting Cu-coated AC exhibited higher specific
capacitance than that of AC under a high cycling rate of 100 C. This result suggests that Cu nanoparticles
play an important role in enhancing the rate capability of AC. The improved cell performance might be
attributed to the reduced charge transfer resistance between the Cu-coated AC electrode and organic
electrolyte while maintaining surface stability.
