Clean energy could get a whole lot cleaner thanks to this breakthrough

One of the tricky conundrums with renewable energy is that the materials used to make the devices and batteries that produce clean energy are made out of unsustainable sources. That’s the main reason why researchers have been working on greener aluminum batteries that could one day replace ones made using lithium.

Lithium-ion batteries are the default choice for most personal electronics and electric cars today because they have a high energy density, but the problem is that lithium is a limited resource, and the process of mining is highly polluting for both the air and local water supplies. In a recent breakthrough, researchers have developed a new form of aluminum battery with twice the energy density of previous designs, making the technology more practical for large-scale projects like solar and wind farms while using more sustainable materials.

The trick was to replace the usual…
