Asphalt helps batteries charge more quickly

Lithium batteries can be made to charge 10 to 20 times faster by using asphalt, suggests US research.

Scientists at Rice University speeded up the charging time by making one component of a battery using carbon derived from the viscous liquid.

In tests, batteries made using asphalt charged to full power in minutes, said the researchers.

They also found that using asphalt stopped the formation of deposits that can shorten the life of a battery.
