One common reason that measured coulombic efficiency (CE) can appear to exceed 100% is a current measurement offset. In this example, assume the cycler has a constant negative current offset e. This means the measured current is lower than the true current by e throughout the test. To simplify the analysis, assume an ideal battery […]
A common end-of-life criterion for lithium-ion cells is when the measured discharge capacity falls to 80% of its initial value. This document demonstrates how to configure an Arbin test schedule to automatically cycle a cell until this threshold is reached. Overall test procedure: Initial capacity measurement → Cycling loop → Compare capacity to 80% → […]
Yes — in both MITS8 and MITS10, formulas are part of the schedule. And this isn’t limited to formulas: other library items such as Pulse, Cyclic Voltammetry, and Test Settings also cannot be changed while a schedule is running. Once a schedule starts, only a very limited set of its elements can be modified. Examples […]
