Density of Cells

cell density

We often look at the (volumetric) energy density (Wh/litre) and specific (gravimetric) energy density (Wh/kg), but if we divide one by the other we get the material density of cells. Using the cell database we can plot this versus the volumetric energy density and pull out the chemistry families. From this we can see: Most … Read more

Benchmarking Battery Pack Volume

BYD Seal battery pack scaled to estimate dimensions

Benchmarking battery pack volume is difficult as not many manufacturers give you a volume or even basic dimensions. This means we have to hunt for the data. Metrics In some cases manufacturers make a claim for the pack volumetric energy density. If you know the total energy the volume is easy to calculate: Scaling Sometimes … Read more
