New Delhi: Experts from around the world, who are looking for ways to stop smartphone batteries and other electronics from dying within a few hours, have come up with a new battery that can fully charge electronic devices in just 10 minutes.

The three-dimensional, silicon-decorated, cone-shaped carbon-nanotube cluster architecture for lithium-ion battery anodes is capable of moving electric current at a very fast speed.

This is way faster compared to batteries that we currently have.
The architecture demonstrates excellent electrochemical stability and irreversibility even at high charge and discharge rates -- nearly 16 times faster than conventionally used graphite-based anodes.

The ultrafast rate of charge and discharge can be attributed to two reasons.

Firstly, the seamless connection between graphene-covered copper foil and carbon nanotubes enhances the active material-current collector contact integrity which facilitates charge and thermal transfer in the electrode system.

And secondly, the cone-shaped architecture offers small interpenetrating channels for faster electrolyte access into the electrode which may enhance the rate performance, Wang explained.
Silicon is a type of anode material that is receiving a lot of attention because its total charge capacity is 10 times higher than commercial graphite-based lithium-ion battery anodes.

The study appeared in the journal SMALL.
