YP-50F is a high-purity, coconut shell-based activated carbon produced by Kuraray Co., Ltd. (Japan). It is widely regarded as the global industry standard for electrodes in Electric Double-Layer Capacitors (EDLCs) due to its extremely stable quality and balanced pore structure. The key advantages of YP-50F are shown below:
(1) High Ion Selectivity: The pore size distribution is optimized for the adsorption of common electrolyte ions like TEA^+ and BF4^-. (2) Low Internal Resistance (ESR): Its high purity and consistent particle size allow for low ohmic resistance, enabling high power density and fast charge/discharge rates. (3) Long Cycle Life: Due to its low ash and metallic impurity levels, it minimizes parasitic chemical reactions, often exceeding $1,000,000$ cycles in commercial cells. (4) Stability: It maintains high capacitance retention even under high-voltage floating conditions or extreme temperatures.
The recipe to prepare electrode slurry for reference:
Active Material: 80– 90% YP-50F
Conductive Carbon: 5–10% (e.g., Super P or Ketjenblack)
Binder: 5–10% (e.g., PTFE for dry-pressing or PVDF for slurry coating)
Solvent: NMP (for PVDF) or Ethanol/Isopropanol (for PTFE)
