Electric Vehicles get another Boost of Acceptance with new Lithium-Ion Battery Charging Speed Upgrade
Researchers have managed to charge a lithium-ion battery to 60 percent in 5.6 minutes...
With many laws being discussed that hope to push electric vehicles to be the standard including President Biden making pushed to phase out gas cars by setting a target that half of all vehicles sold in the United States be electric by 2030.
Plenty of studies has proven that electric vehicles will be better for the environment when compared to gas vehicles but the remaining issue many still throw at efforts is the fact that the charge time is very long. However, a team of researchers working with a handful of institutions in China has successfully managed to increase the speed of charging a lithium-ion battery. According to the report by TechXplore published Thursday found that the researchers have found a way to charge the battery to 60% in just 5.6 minutes.
Within a battery, most anodes consist of graphite and are constructed in a way that is not a practical method for passing along the current. In addition, the way the materials in anodes line up creates an issue related to the gap size between them.
"They first ran particle-level theoretical models to optimize the spatial distributions of different sized particles and electrode porosity. They then took what they learned from the models to make changes to a standard graphite anode. They coated it with copper and then added copper nanowires to the slurry. They then heated and then cooled the anode, which compressed the slurry into a more ordered material.”
The researchers affixed the upgraded anode to a standard lithium-ion battery in order to measure the amount of time it would take to charge. The findings show that they could charge the battery to 60% in just 5.6 minutes and to 80% in just 11.4 minutes.
The question we were all asking is one they did not specify: How much such a battery would cost and when would it be available for production?
The advancement is still very exciting for EVs even more so than Elon Musk!
The study was published in the journal Science Advances.
