Case-studies on Cell Design and Construction using the CAMS model

The Faraday Institution

This post is a compilation of three separate case-studies covering battery cell design and construction. The data and analysis for these case-studies was carried out using the Faraday Institutions CAMS model. CAMS was designed to rapidly assess the potential energy density of different cell chemistries and cell formats. The model can also be used as … Read more

Pack Mass from Cell Density

It is possible to use the battery pack database to estimate the pack mass from cell density. The key relationship we have is between cell and pack gravimetric energy density. This graph has been pulled together by scouring the internet for cell and battery data. The ratio of cell density to pack density is 0.6235 … Read more

Cylindrical Cell Electrode Estimation

Cylindrical Cell Electrode Estimation: An alternative geometric approach. Here we present a simple method for estimating electrode length in a cylindrical cell. The method is equally applicable to other formats since we make an estimation of the total active electrode area. Results require knowledge of one electrode Active Material (AM) chemistry, electrode porosity and thickness … Read more
