Flexible freestanding sandwich-structured sulfur cathode with superior performance for lithium–sulfur batteries†
Abstract
Flexible freestanding sandwich-structured sulfur cathodes are developed for lithium–sulfur batteries, which exhibit excellent cycling stability and rate capability. Moreover, a high areal capacity of ∼4 mA h cm−2 is demonstrated based on this new cathode configuration with high sulfur loading (∼4 mg S cm−2).
