Veggie based 3D printed batteries may charge better: A new 3D printed recyclable battery could provide mobile devices with a higher capacity source of power by using electrodes created from vegetable powder.

This is according to a team of engineers directed by the University of Glasgow, that has published its discoveries in the Journal of Power Sources.

The battery was created to make more sustainable lithium-ion batteries, with the ability of storing & delivering more efficient power.

Scientists desired to expand lithium-ion batteries‘ recyclability & overcome the limits on the amount of energy modern designs can store.

This is thought to be brought about by the thickness of their electrodes. Thicker electrodes limit the movement of lithium-ions throughout the electrode, restricting the energy of lithium-ion batteries.

The scientific group filled their 3D printer with a substance they created which mixes polylactic acid, lithium-iron phosphate & carbon nanotubes.

Polylactic acid is a biodegradable matter developed from the starch of corn, sugar cane & sugar beet.

The new battery testing exhibited its performance is nearly two to three times higher than a conventional lithium-ion battery.

University of Glasgow’s James Watt School of Engineering, Dr Shanmugam Kumar stated: “The 3D printing process we’ve used in this research gives us a remarkable amount of control over the electrodes’ porosity, allowing us to engineer very precisely a new metamaterial capable of addressing some of the shortcomings of the current generation of lithium-ion batteries.

“We’ve created a battery with a high specific capacity and areal capacity with excellent cyclability.”
