Abstract
AbstractThe urgent demand for energy storage systems fueled the development of lithium‐iodine battery, for it is of high energy/power densities and long lifespan and considered as a promising energy storage system. For advanced lithium‐iodine batteries, a free‐standing metal‐organic frameworks (MOF) derived carbon@carbon cloth (MDC@CC) current collector, without using nonconductive binders, was fabricated via in‐situ calcination. Its meso‐micro porous structure and oxygen doping together restricted the shuttle effect and boosted the redox kinetics, leading to the outstanding long‐term cycle performance of MDC@CC. The major contribution of the capacitive effects at high sweep rates leads to impressive high‐rate performance, exhibiting a high capacity of 308 mAh g−1 at 1 C with Coulombic efficiency close to 100 %. Moreover, in long‐term cycling at 10 C, it displays a high capacity retention of 91 % after 3500 cycles.
