The environmental benefits of using electricity rather than fossil fuels to power our world goes without saying however, the process of electrifying everything has its obstacles. Many in the tech world are excited about the new A1-S battery ... declaring that "MIT has produced yet another breakthrough technology that is set to change the world for the better." Researchers at the Massachusetts Institute of Technology (MIT) recently innovated batteries that are made of cost-effective and abundant materials. Instead of using lithium, [MIT Professor Donald] Sadoway and the team ... selected aluminum for one electrode, which he asserted is "the most abundant metal on Earth… no different from the foil at the supermarket." He combined the aluminum with ... sulfur, which he said is "often a waste product from processes such as petroleum refining." Both the charging and discharging cycles generate enough heat that the battery can heat itself and doesn't require an external source. On top of being a fraction of the price of conventional batteries, they can also be charged very quickly with no risk of forming dendrites. It's important to note that this new battery isn't without problems. For instance, the process of extracting alumina out of bauxite is not the easiest or cleanest, and ... researchers are concerned that we may one day run out of [sulfur]. That said, Sadoway made it clear that these issues don't compare to the problems that come with sourcing ingredients for lithium-ion batteries.
