DOI: 10.1002/adma.202203281

Abstract: An ultrastable and kinetically favorable interface is constructed between sulfide–poly(ethylene oxide) (PEO) composite solid electrolytes (CSEs) and lithium metal, via in situ formation of a solid electrolyte interphase (SEI) layer containing Li3PS4. A specially designed… read more here.

DOI: 10.1016/j.apsusc.2018.02.014

Abstract: Abstract Solid-electrolyte interphase (SEI) layer is an organic–inorganic composite layer that allows Li+ transport across but blocks electron flow across and prevents solvent diffusing to electrode surface. Morphology, thickness, mechanical and chemical properties of SEI… read more here.

DOI: 10.1016/j.electacta.2018.12.061

Abstract: Abstract Under over-increasing demand of advanced lithium-ion batteries (LIBs) for long-range electric vehicles (EVs), high-capacity transition metal oxide (TMO) negative electrodes for LIBs are thought as potential substitutes of traditional graphite anodes. A major barrier… read more here.
