What’s the right stack pressure?

what is the best cell pressure - image of a page from the technical paper

A new Nature Energy paper puts a number on it I’ve written before about cell electrode pressure and how it’s applied and lost across a module’s life, and about the practical business of mapping pressure distribution across a pouch cell in operando. Both of those pieces stopped short of answering the question every pack designer … Read more

Effect of Electrode Thickness on Cell Energy Density

In Li-ion batteries, the cathode thickness will heavily influence the energy density of the cell. A thicker cathode means there will be more cathode active material in the electrode. This increases the capacity of the electrode and hence increase the energy density of the cell. However, this relationship is not linear. Using the CAMS model, … Read more
