New Type of Electrolyte Could Enhance Supercapacitor Performance

Supercapacitors, electrical devices that store and release energy, need a layer of electrolyte — an electrically conductive material that can be solid, liquid, or somewhere in between. Now, researchers at MIT and several other institutions have developed a novel class of liquids that may open up new possibilities for improving the efficiency and stability of such devices while reducing their flammability.

Ultracapacitors On UC San Diego’s Microgrid — Smoothing the Sun

Maxwell Technologies has installed the first ultracapacitor energy storage system on UC San Diego’s microgrid. The system, an inconspicuous 20-foot container filled with ultracapacitor modules, supports the solar panels that capture and feed energy to the adjacent La Jolla Playhouse Theater. The goal of the Maxwell ultracapacitor bank installation was to see if ultracapacitors can provide a more cost-effective energy storage system for microgrids—and better response time—than batteries.
