from chemistry to pack
Since I know that this is a delicate topic, and many get confused, I will explain very briefly the nomenclature that I used. The IUPAC defines the anode as the electrode at which the oxidation occurs and the cathode as the electrode at which the reduction occurs. Therefore, in a galvanic cell, the negative electrode … Read more
It is useful to look at an idealised Nyquist Plot of a lithium ion battery. Starting with a detailed, feature-by-feature description of the idealised Electrochemical Impedance Spectroscopy (EIS) Nyquist plot, tracking from the highest frequencies on the left to the lowest on the right. 1. The Axes and Flow 2. The Inductive Artefact (Highest Frequency) … Read more
Battery engineering draws from more disciplines than almost any other field in engineering. A complete battery system requires electrochemistry, thermal engineering, power electronics, embedded software, mechanical design, materials science, and systems integration — all working together, all constraining each other. Most engineers arriving in the field are already expert in one or two of these … Read more
A look at the 2025 Battery Roadmaps. Perhaps closer to describe this as a start of 2025 review of the latest battery roadmaps, research and funding directions that will shape the industry. Here we look at the four largest cell manufacturers and across the government funded research. The big themes are: As China pushes the … Read more
