Cell Manufacturing Strategy

In order to develop cell manufacturing you need a cell manufacturing strategy. This needs to be thought through from access to the raw materials, workforce development, long term financial support and ensuring you have ongoing research. This requires sustained leadership and direction. The strategy for this from the European Battery Alliance (EBA) [2] clearly defines … Read more

Using an ECM to Model HiPot Tests

circuit schematic for HiPot test modelling

Author: Siddharth Kurwa A DC high-potential test (HiPot) is used to detect manufacturing defects in the electrode stack/jelly roll. During the test, a high voltage (orders of magnitude higher than the cell operating voltage) is applied to the cell to screen out early-in-life and latent risks from the production cell population. It is preferred to … Read more

Engineering Empty Space: Tailoring Battery Electrodes for Ion Transport

Author: Anton Resing The cathode layer in a lithium-ion battery is a composite of solid charge storing particles, a polymeric binder, and a conductive additive. Together, they are well dispersed in a solvent and spread like paint on a conductive substrate, an effective and pleasingly simple solution that works across various chemistries and cell designs. … Read more

Battery Module: Manufacturing, Assembly and Test Process Flow.

In this article, we will look at the Battery Module Production. There are 7 Steps for Battery Module Production.

1 GWh of Cells

A look at the numbers around 1 GWh of cells and what could you do with 1 GWh of energy. There are more equivalents for 1 GWh and 1GWh of cells, but hopefully this just helps put the unit into perspective. References Manufacturing Process In order to engineer a battery pack it is important to … Read more
