Abstract:
A new and cost-efficient way of confining the diffusing polysulfides within the sulfur cathode is presented on the basis of employing a porous diatomite that is highly abundant in nature. The sulfur cathode coated with diatomite layer exhibited a significantly reduced capacity fade during the first two cycles, implying that the loss of active materials due to the migration of polysulfides can be mitigated by the protective layer. The diatomite-layered cathode demonstrated excellent cycling stability as high as 85% after 100 cycles. These results clearly indicate that the polysulfide diffusion is effectively blocked and the dissolved polysulfides are well confined within the protected cathode region.
