The case for switching to electric vehicles (EVs) is nearly settled. They are cheaper to use, cut emissions, and offer a whisper quiet ride.. One of the last arguments available to the EV-hater club, which is largely comprised of thinly veiled oil-industry front groups funded by the Koch brothers, focuses on the impacts from the materials used to …
Cerium, a unique rare earth element, possesses a relatively high abundance, low cost, and high redox voltage, making it an attractive candidate for redox flow batteries. However, the sluggish kinetics and corrosion nature of the Ce 3+ /Ce 4+ electrolyte result in overpotential and degradation of carbon felt (CF) electrodes, which …
