Operando Small-Angle Scattering Investigation of the Lithium/Sulfur Battery - Are Structural Features of the Nanocarbons Important?

摘要

Great deal of studies have been focused on the energy conversion and storage devices. Among them, lithium/sulfur battery (Li/S) with the high gravimetric energy density (～730.0 Wh/kg) and affordability (sulfur is an earth-abundant element). Targeted research could promote the commercialization of Li-S batteries in a more efficient way and keep up with challenges for building continual batteries in terms of performance and energy density, which are greatly influenced by the multi-phase interfacial reactions, polysulfide equilibria and shuttling as well as by the electrolyte decomposition under the operating conditions.
