Researchers from the University of Electronic Science and Technology of China and the Tianmu Lake Institute of Advanced Energy Storage have designed a battery, which is rather more robust than the norm, operating as you’d expect even when folded in two — or cut straight across the middle.
“Herein, we design a series of chelating-type binders to stabilize MSₓ [metal sulfides] in carbonate-based electrolytes,” the team explains of its work. “Additionally, we have developed a new battery system featuring an MSₓ cathode paired with a prelithiated graphite (LiC₆) anode in a carbonate-based electrolyte, with the aim of achieving higher safety and satisfactory stability.”

While the team’s paper concentrates primarily on the chemistries involved, it’s the prototype battery that is likely to be of most interest to the layman: based on a…
