China leads the Race for Ultra-Fast Charging EV Batteries

The world’s biggest battery makers are working to make electric vehicles more attractive to hesitant buyers by offering a five-minute charge time for a decent range that would give drivers the same superfast experience as they would have at a gas station.
Currently, the charging times for EVs range anywhere from 20 minutes to 50 or more hours, depending on the charger types and speeds, as well as the vehicle battery capacity.
Some battery makers have recently unveiled batteries capable of charging to 80 percent in fewer than 10 minutes and say that technological advances will soon lead to the five-minute charge that would revolutionize the EV driving experience.
However, experts point to faster exhaustion of the battery’s lifespan in excessive superfast charging and increased risks of battery fires with overheating during the under-10-minute charge.
In addition, the lack of superfast charging is only one of the current anxieties for drivers considering buying an EV. Others include not enough public charging points for a convenient car trip at longer distances, the cost of buying and keeping an EV with uncertainties about incentives, and expensive battery replacement.
The Chinese battery manufacturers are leading in the race to superfast charging as their lithium iron phosphate (LFP) batteries are not as susceptible to overheating as the nickel-cobalt chemistry in the batteries of their competitors in South Korea.
China’s Contemporary Amperex Technology Co., Limited (CATL), the world’s biggest battery maker, which supplies batteries to Tesla and BMW, among others, unveiled in April the world’s first LFP battery that achieves a range above 1,000 kilometers (620 miles) with 4C superfast charging.
