Encapsulation of sulfur with thin-layered nickel-based hydroxides for long-cyclic lithium¨Csulfur cells
Abstract£ºElemental sulfur cathodes for lithium/sulfur cells are still in the stage of intensive research
due to their unsatisfactory capacity retention and cyclability. The undesired capacity
degradation upon cycling originates from gradual diffusion of lithium polysulfides out of the
cathode region. To prevent losses of certain intermediate soluble species and extend lifespan
of cells, the effective encapsulation of sulfur plays a critical role. Here we report an applicable
way, by using thin-layered nickel-based hydroxide as a feasible and effective encapsulation
material. In addition to being a durable physical barrier, such hydroxide thin films can
irreversibly react with lithium to generate protective layers that combine good ionic
permeability and abundant functional polar/hydrophilic groups, leading to drastic improvements
in cell behaviours (almost 100% coulombic efficiency and negligible capacity decay
within total 500 cycles). Our present encapsulation strategy and understanding of hydroxide
working mechanisms may advance progress on the development of lithium/sulfur cells for
practical use.
