When a battery is discharging the electrons, e– , move from the – to + terminal and while it is charging the electrons travel from the + to the – terminal. These electrons are generated by the reduction and oxidation reactions (redox) inside the cell. Oxidation is loss (OIL) of electrons and Reduction is gain … Read more

Cylindrical Cell Comparison 4680 vs 21700 vs 18650

In this Article, we will compare different Cylindrical Cell Sizes used in electric Vehicles. 4680 vs 21700 vs 18650.

Tesla 4680 Cathode Porosity

Indicative numbers for the Tesla 4680 cathode porosity, estimated based on 2D images of the Batch 1 and 2 cells originally analysed for The Limiting Factor by the Laboratory for Energy Storage and Conversion, UC San Diego. This image analysis and estimation was performed by Addionics based on the original Tesla 4680 cell benchmarking. Analysis … Read more
