Abstract:
All-state-state lithium batteries (ASSLBs) have gained worldwide attention because of the high ionic conductivity of SEs, intrinsic safety and increased energy density. In ASSLBs, solid-state electrolyte is a key component and interface is a big challenge. In this talk, I will talk about two types of solid-state electrolytes including sulfide-based electrolyte (focusing on interface) and halide-based electrolytes (focusing on synthesis).
In the first part of this talk, I will demonstrate to apply ALD/MLD for interface design between sulfide-based electrolyte and cathode material. Atomic layer deposition (ALD) and molecular layer deposition (MLD) are unique coating techniques that can realize excellent coverage and conformal deposition with precisely controllable at the nanoscale level due to its self-limiting nature, which are ideal for addressing the challenges of interface in SSLBs [1-2].
In the second part of this talk, I will talk about halide-based electrolyte for ASSLBs. Compared with sulfide-based electrolyte, both experimental and theoretical results recently demonstrate that halide-based electrolytes have more advantages including high RT ionic conductivity (10-3 S cm-1, theoretically possible 10-2 S cm-1), wide electrochemically stable window (possible up to 6 V), high air-stability, good stability toward oxide cathode materials, and even salable water synthesis strategy [3-6].

Biography:
Dr. Sun is a Full Professor and a Canada Research Chair at the Western University, Canada. Dr. Sun received his PhD in Materials Chemistry under direction of Prof. George Thompson in 1999 at the University of Manchester, UK, followed by work as a postdoctoral fellow under direction of Prof. Keith Mitchell at the University of British Columbia, Canada, and as a Research Associate under direction of Prof. Jean-Pol Dodelet at l’Institut national de la recherché scientifique (INRS), Canada. His current research interests are associated with synthesis of low-dimensional nanomaterials for electrochemical energy storage and conversion. His research focus is on design and synthesis of various one-dimensional nanostructures such as nanotubes, nanowires, nanoparticles and nanofilms as well as their composites as electrocatalysis and catalyst support in fuel cells and as anode and cathodes in lithium-ion batteries and Li–air batteries.
