  1. 1. Elucidating Chemical and Electrochemical Side-Reaction Mechanisms in Li-ion Batteries

    Author : Neeha Gogoi; Erik Berg; M. Rosa Palacín; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Lithium-ion battery; solid electrolyte interphase; electrolyte additives; reaction mechanism; ethylene carbonate; vinylene carbonate; tris trimethylsilyl phosphate; surface enhanced Raman spectroscopy; Kemi med inriktning mot materialkemi; Chemistry with specialization in Materials Chemistry;

    Abstract : Lithium-ion batteries constitute a leading technology that plays a major role in the transition towards sustainable transportation and power generation. The stability of modern batteries relies on a passivation layer formed on the negative electrode known as the solid electrolyte interphase (SEI). READ MORE
