With trash being one of the most ubiquitous elements on the planet. Isn’t it reassuring when one hears that researchers have created a method of using discarded trash to make sodium-ion batteries? Well it’s a reality! Made from recycled materials these batteries are safer than their lithium counterparts, and are seen as a strong candidate for future renewable energy storage.
Scientists were able to fashion the batteries from rusty, recycled stainless steel mesh. Using a potassium ferrocyanide solution (such as those found in fertilizers) and use it to dissolve the ions embedded in the layer of rust. Following a complex chemical process, the batteries allowed for conductivity and energy storage.
These new batteries are said to be safer and possess a high capacity and stability.
Having created renewable energy from trash, the scientists are now aiming to refine their designs to maximize all available power! Way to go guys!
