Super Energy Combo Could Charge Car in Minutes


For years, engineers have been trying to reduce the cost of “ultracapacitors,” devices that store more energy than batteries and discharge it in an instant. That kind of capability is the ultimate power source for advanced electric cars, trains or airplanes.

Now, a team of researchers at George Washington University says they’ve figured out how to build a low-cost ultracapacitor by combining carbon nanotubes and graphene.

Because of the quick-discharge and big capacity, electric car owners could charge in minutes instead of plugging in overnight, according to Shashurin.
“It’s very fast,” said Alexey Shashurin, a research scientist in mechanical and aerospace engineering at GWU.
Single-walled carbon nanotubes and graphene both have electronic, thermal and mechanical properties that make them good materials for new ultracapacitors, said Jian Li, first author on the paper, which appears in the Journal of Applied Physics.
Many groups have explored…
