Battery designers face many challenges, but two stand out. One is developing small, heavy-duty batteries. These units hold a really big charge. The other is being able to recharge such batteries hundreds of times without them losing their ability to hold a boatload of energy. A team of scientists now reports having achieved both feats. It involved adding sulfur to their battery’s recipe.

 

Oh, and unlike earlier attempts to build sulfur-based batteries, these aren’t prone to explode.
