Scientists at Rice University are getting faster charging with asphalt in the battery. As reported by BBC, during tests it was found that batteries made using asphalt charged to full power in minutes. Additionally, they also reported that asphalt stops the formation of deposits that can shorten the life of a battery.
In a news published by the Rice University, Prof James Tour has stated that
“The capacity of these batteries is enormous, but what is equally remarkable is that we can bring them from zero charge to full charge in five minutes, rather than the typical two hours or more needed with other batteries.”
Rice team used carbon derived from asphalt to make these batteries. The component was mixed with graphene nanoribbons and then later coated with lithium metal.
The Rice team has put prototype batteries through hundreds of cycles of charging and discharging to ensure the technology is stable. This testing also revealed that the batteries were less likely to suffer the build-up of structures called “lithium dendrites” that can gradually spread through a device limiting its life.
According to the team working on this product, asphalt may be the secret to high-capacity lithium metal batteries that charge 10 to 20 times faster than commercial lithium-ion batteries.
