Developed another effective analogue of modern lithium-ion batteries


Breaking addiction to costly andharmful to the ecology of the Earth lithium-ion batteries seek many teams of scientists offering original ideas for autonomous power sources. Another idea is proposed by a team of enthusiasts from Chalmers University of Technology Sweden and the National Institute of Chemistry in Slovenia, who proposed using aluminum as a basis for batteries.

Using cheaper and more environmentally friendlyharmless compared to lithium material can lead to revolutionary changes in battery production. However, there is an extremely negative technical property of an aluminum-based battery - this is a low energy storage density. The existing aluminum batteries use graphite as the cathode, which significantly reduces battery performance. Scientists have proposed using an organic compound instead of graphite.

According to a new proposal by an international group of scientists, the graphite cathode was replaced by an organic nanostructured cathode based on the carbon molecule anthraquinone.


According to the developers of the innovation modelThe advantage of using an organic molecule in the cathode material is the ability to maintain positive charge carriers from the electrolyte, which allows you to create a higher energy density in the battery. The energy density as a result doubles.

Opportunity currently under studyuse aluminum to create the next generation of batteries. The current task of the developers is to create a safe electrolyte for the operation of aluminum batteries, since now unsafe chlorine-containing material is used for this.
