US team’s battery ‘breakthrough’

See on Scoop.itGreen Energy Technologies & Development

Researchers believe they have found a way to radically shrink the size of batteries while offering the same amount of power and faster recharges than at present.

Duane Tilden‘s insight:

>The scientists’ “breakthrough” involved finding a new way to integrate the anode and cathode at the microscale.

“The battery electrodes have small intertwined fingers that reach into each other,” project leader Prof William King told the BBC.

“That does a couple of things. It allows us to make the battery have a very high surface area even though the overall battery volume is extremely small.

A cross-section of the battery reveals the 3D-design of the research project’s anodes and cathodes

“And it gets the two halves of the battery very close together so the ions and electrons do not have far to flow.

“Because we’ve reduced the flowing distance of the ions and electrons we can get the energy out much faster.”<
