Base vs Side Cooling Cylindrical Cells

cylindrical cell base versus end cooling

Base vs side cooling of cylindrical cells is often brought up in online discussions and in many OEMs designing battery packs. We looked at this before within Thermal Conduction in a Cell, however, I think it is worth expanding this topic. The Tesla design cools the side of the cell and the Lucid Motors cools … Read more

Cell Gas Pressure

Gases are generated in the cathode, anode and electrolyte during the formation and cycling of a battery cell. As this is a closed system the result is a cell gas pressure. What this gas is composed of, how it behaves and how it changes with State of Charge (SoC) and the cycling of the cell … 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
