The present invention relates to a hybrid supercapacitor comprising electrodes having a composition of 87.5 to 96.5 mass% of an active material, 2.5 to 7.5 mass% of a conductive additive, and 1 to 5 mass% of a binder, To 40 mass% LiMn 2 O 4 (LMO), and b) 60 to 70 mass% of activated carbon. The active material of the cathode electrode comprises a) 20 to 30 mass% of Li 4 Ti 5 O 12 (LTO) b) 70 to 80% by mass of activated carbon. The ratio of the active mass of the cathode electrode to the anode electrode is in the range of 0.4 to 1.2. |
