Researchers explore proton-hopping mechanism to improve EV batteries

Researchers at Oregon State University have shown that a chemical mechanism known as proton-hopping may provide a new method of energy storage for EVs and other high-power applications. “Coming up with Faradaic electrodes that afford batteries energy density and capacitors power with excellent cycle life has been a big challenge. So far, most of the… Read more »

New motor cooling solution could lead to lighter EVs

Researchers from the Fraunhofer Institute for Chemical Technology and the Karlsruhe Institute of Technology have developed a new method for cooling electric motors, which could help reduce the weight of EVs. With the new cooling method, motors can be housed in lighter-weight polymer materials, and they also benefit from increased efficiency and power density. The… Read more »

KAIST research team develops stable, high-rate Li-S batteries

A research team from South Korean research university KAIST has developed stable, high-rate lithium-sulfur batteries (LSBs) by using hierarchically porous titanium nitride (h-TiN) as a sulfur host. In a paper in the journal Advanced Materials, the researchers report that h-TiN/S shows a reversible capacity of 557 mAh g-1 even after 1,000 cycles at 5 C rate with only… Read more »
