Lithium-ion (Li-ion) batteries are seen as the great hope for the future of battery technology because of their immense potential for long-life cycles and energy density. However, degradation is one of Li-ion batteries’ toughest challenges. To eliminate the degradation and extend the lifespan, scientists need to figure out what causes IT in the first place. In a paper published in Energy & Environmental Materials, the University of Surrey, together with TESCAN and the Oak Ridge National Laboratory explain a new way to detect and investigate Li-ion’s degradation mechanisms.
