Researchers have developed a groundbreaking electric vehicle (EV) battery that can charge rapidly, even in frigid temperatures.
On Thursday, InsideEV reported that a joint research team from the University of Michigan and Arbor Battery Innovations created a battery capable of fully charging in 10 minutes at -10°C (14°F). Remarkably, the battery shows minimal performance degradation even after 100 charge cycles.
Conventional EV batteries have long struggled with reduced charging speeds and diminished driving ranges in cold conditions. The research team employed laser processing on the anode’s graphite to overcome this challenge, facilitating faster lithium-ion movement. They also applied a lithium borate-carbonate coating to prevent lithium plating on the anode surface, resulting in a battery that can fully charge in 10 minutes at a 6C rate even at -10°C (14°F).
This breakthrough has captured industry attention due to its potential for integration into existing battery manufacturing processes without major overhauls. However, InsideEV noted that the capacity and charging range of the experimental batteries have not been fully disclosed, suggesting that further testing is necessary to determine their viability for real-world automotive applications.
