Building better batteries: Researchers untangle the tiny strands of lithium that develop inside rechargeable batteries

When we plug in our cell phones to charge them, we take it for granted that they'll soon be brimming with energy for scrolling, texting and receiving news alerts. But the technology powering this—rechargeable lithium-ion batteries—heralded a genuine technological revolution when these batteries first appeared on the commercial scene in the 1990s,
The article from TechXplore discusses a breakthrough in battery technology where researchers have developed a method to untangle the tiny strands of lithium that form during the charging process of lithium metal batteries. This innovation, led by a team at Stanford University, involves using a special electrolyte that helps in preventing the formation of lithium dendrites, which are needle-like structures that can cause short circuits and reduce battery life. By controlling the growth of these lithium structures, the new approach promises to enhance the safety, lifespan, and efficiency of lithium metal batteries, potentially revolutionizing energy storage for electric vehicles and portable electronics. The study, published in Nature Energy, highlights the potential for this technology to overcome one of the major hurdles in the commercialization of high-energy-density batteries.
