New electrolyte goes extra mile for faster EV charging.
Oak Ridge National Laboratory researchers are taking fast charging for electric vehicles, or EVs, to new extremes.
A team of battery scientists recently developed a lithium-ion battery material that not only recharges 80% of its capacity in 10 minutes but keeps that ability for 1,500 charging cycles.
When a battery operates or recharges, ions move between electrodes through a medium called the electrolyte. ORNL’s Zhijia Du led a team who developed new formulations of lithium salts with carbonate solvents to form an electrolyte that maintains better ion flow over time and performs well when high current heats up the battery during extreme fast charging.
Project partners tested battery pouch cells made at ORNL’s Battery Manufacturing Facility to prove the battery’s safety and cycling characteristics.
“We found this new electrolyte formulation basically triples the Department of Energy’s target for the lifespan of an extreme-fast-charging battery,” Du said.
