Researchers figure out how to get fresh lithium into batteries
As the owner of a 3-year-old laptop, I feel the finite lifespan of lithium batteries acutely. It's still a great machine, but the cost of a battery replacement would take me a significant way down the path of upgrading to a newer, even greater machine. If only there were some way to just plug it in overnight and come back to a rejuvenated battery. While that sounds like science fiction, a team of Chinese researchers has identified a chemical that can deliver fresh lithium to well-used batteries
