The National Aeronautics and Space Administration (NASA) has a need for high-rate discharge batteries and electric motors that can drive an electric pump to power a set of lander engines in support of their Mars…
Supercapacitors can charge almost instantly and discharge enormous amounts of power if needed. They could completely erase the Achilles heel of electric vehicles – their slow charging times – if they could hold more energy….
Engineers from the University of California at Los Angeles ( UCLA), four other universities produce nanoscale device that mimics the structure of tree branches. Mechanical engineers from the UCLA Henry Samueli School of Engineering and Applied Science and four other institutions have designed a super-efficient and long-lasting electrode for supercapacitors. The device’s design was inspired
