Understanding Solid Electrolyte Interface (SEI) to Improve Lithium …

SEI formation: In Li-ion batteries, for the first charging, the quantity of lithium-ion given by the positive electrode is less than the number of lithium ions travelled back to the cathode after first discharging. This is due to the formation of SEI (solid electrolyte interface). For the first few charge and discharge cycles, when electrolyte …

Four-Probe Method | Sheet Resistance Formula

Sheet resistance is a critical property for any thin film of material in which electrical charges are intended to travel along (rather than pass through). For example, thin-film devices (such as perovskite solar cells or organic LEDs) require conducting electrodes which generally have thicknesses in the nanometre to micrometre range.
