Scientists at the University of Michigan have succeeded in creating a new type of membrane from recycled Kevlar that could facilitate the development of lithium-sulfur batteries. These batteries could prove to be up to five times more efficient than the models currently used by the automotive industry. This brand new type of battery membrane has enabled the development of a lithium-sulfur battery capable of operating for more than a thousand cycles, without loss of performance. As a side note, the recycled Kevlar used in this work is similar to that used in bulletproof vests. Scientists alread…
