Supercapacitors News

Supercapacitors, also known as ultracapacitors, are high-capacity capacitors that store electrical energy through electrostatic mechanisms, offering significantly greater capacitance than traditional capacitors. They bridge the gap between conventional capacitors and rechargeable batteries, providing rapid charging and discharging, high power density, and the ability to endure hundreds of thousands of charge cycles without significant degradation. Unlike batteries, which produce energy through chemical reactions, supercapacitors store energy in an electric field created between two electrodes immersed in an electrolyte. This design allows them to release energy much faster than batteries and makes them ideal for applications requiring quick bursts of power, such as in regenerative braking systems in vehicles or for power stabilization in electrical grids. Despite their advantages in power management and cycle life, supercapacitors currently have a lower energy density compared to batteries, limiting their use as a sole energy storage solution in many applications.
