### A new eco-friendly battery concept made from abundant materials has twice the energy density compared with previous versions

As part of the push to move away from batteries that use rare earths, researchers from Sweden and Slovenia have unveiled a battery concept with twice the energy density compared with previous attempts. The battery is made with aluminum, which in addition to being high-density, has the added significant benefits of being ubiquitous and well-established in manufacturing and recycling.
