Scientists Discovered a Way to Make Your Batteries Survive Way Longer

Scientists at the SLAC-Stanford Battery Center have discovered a method to enhance the lifespan of lithium-ion batteries by 50%. This breakthrough centers on the first charge of the battery, which significantly influences its overall performance and longevity. The research indicates that charging batteries at unusually high currents during their initial charge can reduce charging time from 10 hours to just 20 minutes while extending battery life. The study, published in the journal Joule, involved collaboration with researchers from the Toyota Research Institute, MIT, and the University of Washington. The findings suggest that the initial charge depletes a portion of the lithium supply, which is typically lost to form a protective layer on the battery's negative electrode. This loss, while seemingly detrimental, actually contributes to a more robust solid electrolyte interphase (SEI) that protects the battery from degradation over time. Historically, the formation charge was conducted at low currents to create a strong SEI, but this new approach demonstrates that high currents can yield better results. If implemented in commercial battery production, this technique could lead to longer-lasting batteries for devices like smartphones and cameras.
