Electrode electrolyte interphase (EEI) is a crucial determinant of battery performance and durability. Organic solvents and inorganic electrolytes decomposes to chemically active radicals under electrical potential near the electrode surface. A thin film consists of mosaic nano-scale structures, generated by organic and inorganic decomposed products is deposited on electrodes thus creates an interphase between electrode […]
