Maxwell Technologies says the North American office of United Kingdom’s Vehicle Certification Agency (VCA) has granted European Economic Community (EEC)-Type Approval and Conformity of Production (CoP) clearance to Maxwell’s 125-volt Heavy Transportation Module (HTM125). The 125V heavy transportation series of ultracapacitor modules is a high performance energy storage and power-delivery product line for hybrid buses…
Activated graphene promises to make super supercapacitors
Scientists at the U.S. Department of Energy’s Brookhaven National Laboratory have helped uncover the nanoscale structure of a novel form of carbon, contributing to an explanation of why this new material acts like a super-absorbent sponge when it comes to soaking up electric charge. The material, recently created at The University of Texas – Austin,…
Supercapacitors with Lower ESR on the Scene
5F SuperXcaps capacitors handle 5 A maximum and is rated with an ESR (dc) of 70 mΩ. Typical competitive units offer a maximum of only 3.4 A current and an ESR (dc) of 200 mΩ. This means the time constant, (ESR x Capacitance) of the SuperXcap is far lower. Faster charging (and discharging) performance significantly…
