from chemistry to pack
AION Engineering INC In battery continuum modelling, few parameters are as universally accepted—and as fundamentally flawed for modern cells—as a Bruggeman exponent of 1.5. While it is widely understood that tortuosity and porosity are distinct structural metrics, the industry consistently defaults to this idealized constant to bridge the gap between them. To understand why modern … Read more
The Comparative Tracking Index (CTI) is a standardized measurement that quantifies an insulating material’s resistance to surface “tracking”. Tracking is the progressive degradation of a material’s surface, where moisture, dust, and continuous voltage stress cause localized leakage currents that slowly carbonize the material, eventually forming a permanent conductive path. Let’s look deeper into how CTI … Read more
Cell electrode pressure and expansion are elements that we need to consider when designing any battery pack. This is perhaps even more important when looking at large cell to pack designs. During the charge and discharge processes, Lithium Iron Phosphate (LFP) cells experience highly restricted cell volume variation. This structural stability is fundamentally attributed to … Read more
Not sure the website is ready for a newsletter for batterydesign.net, but we needed to start somewhere. Having started the Newsletter for BatteryDesign.net it has gained traction and as of January 2023 has over 500 subscribers. Please feel free to forward the newsletter email to friends and colleagues in the battery design industry. We would … Read more
