Researchers at Melbourne, Australia’s RMIT University developed an acoustic device that can remove performance-inhibiting rust from batteries, tripling their lifespan and, hopefully, reducing how frequently they are discarded. The researchers used MXene, a nano-material that holds promise as an alternative to lithium batteries, yet is prone to rust. They discovered that high-frequency sound waves cause the MXene battery to vibrate with enough force for the …
