Scientists at the University of Buffalo experimenting with next-generation battery designs have demonstrated how magnetism might be used to bring a new level of precision to the way we monitor a battery’s state of charge.
The breakthrough hinges on a novel electrode design that induces shifts in a magnetic field as ions arrive and depart, which is can reveal battery life with a high degree of accuracy.
Using vanadium, chromium, and cyanide, the scientists created a novel magneto-ionic material, which they deployed as a “molecular magnetic electrode” in a lithium-ion battery. The material changes its magnetism as lithium ions enter and leave, and by using a ferromagnetic resonance testing unit, they were able to measure those changes to reveal the battery’s charge level.
Ferro-Alloy Resources Limited (LON:FAR) is developing the giant Balasausqandiq vanadium deposit in Kyzylordinskaya oblast of southern Kazakhstan. The ore at this deposit is unlike that of nearly all other primary vanadium deposits and is capable of being treated by a much lower cost process.
