| Abstract Scope |
All solid-state lithium-sulfur battery (ASSLSB) is a promising next-generation battery technology for vehicle electrification due to its high energy, low cost, and high safety. Although issues of polysulfide dissolution and Li corrosion existing in liquid Li-S cells are fully eliminated, achieving both high energy and stable cycling is still very challenging for ASSLSB. This is due to extremely low ionic/electronic conductivities of S and Li2S, which relies on the effectiveness and completeness of Li+/e- conduction networks. The other grand challenge of ASSLSB is how to achieve dendrite-free Li cycling at both high current densities and areal capacities. Properties of Li/SSE interface impacts early-stage Li nucleation, which dictates subsequent Li growth and cycling. To overcome those issues, rational designs of materials, electrode, and interface are needed. At the conference, we will discuss our understandings of those key challenges and progresses we achieved in addressing them. |
