Silicon-based materials offer a wide range of benefits for Li-ion battery applications. In comparison to carbon-based anodes, higher energy densities can be reached, and compared to lithium metal, silicon-based materials offer a reduced dendrite formation at similar capacity. Moreover, silicon-based anodes enable fast-charging and significantly easier processing, which is suitable for most existing production lines. […]

Equivalent circuit models (ECMs) are used widely in the battery and vehicle industry today in battery management systems or for battery system simulation. Low accuracy can cost performance, reduce accuracy in state estimation and influence further parameters in a negative manner. Therefore, one places accuracy goals on the models which are developed. But of course, […]
