Researchers have develop a novel EV battery tech that can charge an EV battery in just ten minutes, paving the way for the mass adoption of much more affordable electric vehicles.
This technology has develop by researchers from Penn State and it’s base on internal thermal modulation, an active method of temperature control to pull the best performance possible from the battery.
Researchers explain that batteries operate most efficiently when they’re hot, but not too hot.
Keeping the temperature consistent at the perfect sweet spot has a challenging endeavour for battery engineers.
Researchers in the past have relied on external, large heating and cooling systems for battery temperature management, which doesn’t work as promptly and also ends up wasting energy along the way.
Penn State’s Researchers decide to try a different approach which regulate the temperature from inside the battery.
Researchers created a new battery structure with an ultrathin nickel foil as the fourth component alongside anode, cathode and electrolyte.
Nickel, acting like a stimulus, self-regulate the battery’s temperature and reactivity that allow for 10-minute fast charging on any EV battery type.
Chao-Yang Wang, the William E. Diefenderfer Professor of Mechanical Engineering at Penn State and lead author on the study, explained :
Researchers in the study conclude stating that true fast-charging batteries could have an immediate impact, as there are not enough raw materials for every internal combustion engine car to be replace by a 150kWh-equip EV, fast charging is imperative for EVs to become mainstream.
