Quantitative Solid Electrolyte Interphase-Based Descriptors for Lithium Liquid Electrolyte Design
… This shortfall derives from parasitic Li-electrolyte reactions that lead to accumulation of inactive Li⁰ and electrolyte-derived byproducts, which result in the formation of a native solid electrolyte interphase (SEI). The SEI is an electrolyte-derived passivating layer that ideally …

Composite Gel Polymer Electrolyte for Lithium Ion Batteries
… polymer batteries with solid polymer/composite electrolyte were introduced where the safety drawbacks of the liquid electrolyte were eliminated but the ionic conductivity of the batteries was lower than that of a liquid. In this work, composite gel polymer electrolyte (CGPE) films, consisting of …

Ionic volumes, compressibilities and electrostriction of electrolyte solutions.
A theory of electrostriction of solvent water near ions is developed. The treatment is based on a calculation of the effective pressure which would, in the absence of the field, cause the she change in volume as does the field. It is shown that when the dissolution process is from the crystalline …
