Scientists make mind-blowing breakthrough in battery safety with prototype that actually works when cut: 'The battery continues to function'
Chinese battery researchers have developed two lithium-sulfur batteries, one that remains stable after 300 charge/discharge cycles and another that provides power after being cut in half or folded. The batteries' resilience is due to a unique cathode coating. Lithium-sulfur batteries have the potential to be cheaper than lithium-ion alternatives, but they can take hours to charge. The breakthrough could lead to safer batteries and make lithium-sulfur technology more mainstream.
