Researchers at MIT have discovered that lithium-ion batteries produce unique sounds as they fail, similar to how people show signs of distress. By decoding these acoustic signals, they can predict battery problems before they lead to serious failures. This breakthrough could help prevent dangerous situations and improve battery safety overall.
