Supercapacitors and the Potential to Revolutionize Energy Storage & Power Delivery

In this white paper, Abracon® discusses Supercapacitors and their potential to revolutionize energy storage and power delivery. Supercapacitors, also known as ultracapacitors, are increasingly adopted in various industries because they have a composition and features from both regular capacitors and batteries. They include two electrodes, an electrolyte solution, and a porous membrane separator allowing ion travel. During charging, negatively charged ions create a Helmholtz layer on the electrode surface. Supercapacitors are categorized into electric double-layer capacitors (EDLCs), pseudocapacitors, and hybrid capacitors based on factors like fabrication technology and materials. EDLCs store energy as an electric field, pseudocapacitors utilize conducting polymers and metal oxides for intercalation, and hybrid capacitors combine electrostatic storage in the cathode with electrochemical storage in the anode, as seen in lithium-ion capacitors (LiCs).
