BATTERIES - New sulfur-rich copolymer electrodes for Li-S batteries exhibit high-capacity, long-life

Cycling performance of Li?S battery from 10% by mass DIB copolymer batteries to 500 cycles with charge (filled circles) and discharge (open circles) capacities, as well as Coulombic efficiency (open triangles). The C-rate capability of the battery is shown in the figure inset. Credit: ACS, Simmonds et al.
