While many revolutions are announced in the field of batteries without any tip tip for the moment, all initiatives are good to take, and a new study brings interesting results.
These small pieces of polystyrene which are used to wedge the items in the boxes when sending parcels are not often recycled, and yet they could contribute to the production of more efficient batteries than those currently available.
Researchers from Purdue University have developed a carbonization process capable of transforming these wedges into carbon anodes. In addition to participating in the recycling of a polluting component which takes more than 100 years to disintegrate in nature, the anode produced would allow batteries to be recharged much faster.
The anodes thus created are only a tenth of their equivalent currently sold in lithium-ion batteries, they thus produce almost no electrical resistance.
For now, research is focused on the ability of these new batteries to absorb a large number of cycles. Currently, the first models last around 300 charge cycles before losing their capacity, an honorable figure, but little adapted to the needs of consumers for products supposed to last several years.
The approach is at the same time simple, economical and ecological. What is more, it is scalable. It will probably take a few more years before arriving at a battery model equipped with this new anode. Hopefully, by then, other projects will also have come to fruition.
