  • Prismatic Cell Electrode Estimation

    Using some simple mathematics and dimensions we can do some prismatic cell electrode estimation. The above schematic is just one of many prismatic cell layouts and we will need to cover the other orientations and the cases where there is more than one jelly roll. For now let us layout the simple estimation using the…

  • Pack Level Chemistry Comparison

    In this pack level chemistry comparison we have taken some generic chemistry values for NMC, LFP. LTO and NaB. Thus allowing us to do a very high comparison. The tool for this comparison is available in the Battery Calculations Workbook. Cell Data For the cells we have Open Circuit Voltage (OCV) values as an average…

  • Weld Mechanical and Electrical Properties

    Is there a relationship netween weld mechanical and electrical properties? The basic conclusion is that low electrical resistances were found to correlate with high mechanical strengths of the welds. Correlation between electrical resistance and tensile strength for welds produced with (blue markers) and without (red markers) spatial beam oscillation. [1] This post has been built…
