Available discharge energy of non-aqueous electrochemical energy storage cells vs. discharge current
Available energy is one of the most relevant parameters for dimensioning and design of battery systems. The discharge duration of a battery and its dependence on the amplitude of the discharge current are described by Peukert’s equation. Other equations describe this dependence up to very high currents, including the currents that occur during a short […]
A Multi Scale Multi Domain Approach For The Modelling Of Large Format Lithium-Ion Battery Cells
The physical processes in a lithium-ion battery (LIB) cell take place on various length scales. While MSMD models have been established to calculate the electrochemistry on the micrometer scale and map e.g. the temperature distribution in the entire battery cell on the mesoscale at the same time, two challenges remain for modeling large format cells: […]
