Our partner from Carbon-Ukraine (CU) has recently published a GREENCAP article titled: “Increasing Specific Capacitance by Optimization of the Thickness of Carbon Electrodes” in Batteries & Supercaps. This study addresses the challenge of increasing the energy density of electrochemical capacitors without compromising their lifespan, power output, or cycle stability. While most research focuses on enhancing active charge-storing materials, less attention has been given to optimizing device design and reducing the weight and volume of passive components. The authors presented a mathematical model for a carbon supercapacitor with an organic electrolyte, which establishes a relationship between the specific capacitance, electrode thickness, and the weight of passive components, such as cases and current leads. The model, grounded in experimental data, was validated using electrodes made from two porous carbon materials. Results indicate that, across a range of electrode thicknesses, the specific capacitance varies linearly with thickness. This model offers a method for optimizing electrode thickness to maximize specific energy density, tailored to specific carbon electrode materials.
Congratulations to CU on this impressive achievement!
