  • Understanding fluorine-free electrolytes via small-angle X-ray scattering

    We compare the solvation phenomenon of sodium tetraphenylborate (NaBPh4) salt dissolved in organic solvents of propylene carbonate (PC), 1,2-dimethoxyethane (DME), acetonitrile (ACN) and tetrahydrofuran (THF) by SAXS/WAXS measurement and MD simulation. Read More

  • Navigating the Minefield of Battery Literature

    This is an invited perspective aiming to help researchers new to the field of battery research to circumvent certain recurring misconceptions and inaccuracies in the current battery literature. It covers the electrolyte ideality and practical situation in batteries, the difficulty in accurately determining ion transference … Read More

  • Quantifying Lithium Ion Exchange in Solid Electrolyte Interphase (SEI) on Graphite Anode Surfaces

    By using Li isotopic labelling of SEIs and electrolytes followed by time-of-flight secondary-ion mass spectroscopy and solid-state NMR analyses, we found that the majority of Li+ “immobilized” in the chemical ingredients were exchanged after 1 SEI formation cycle. Ion exchange by diffusion based on concentration … Read More
