from chemistry to pack
Quick facts The prompt for this piece Prof Louis Piper (WMG/Warwick, Faraday Institution) posted a summary of this paper on LinkedIn, describing work from the Faraday Institution’s LEAP project led by Eleni Fiamegkou and Daniela Proprentner. His framing of the result is worth repeating directly, because it’s the thesis the underlying data set out to … Read more
AION Engineering INC Anode Electrode Porosity vs. Energy Density: The Turning Point in High-Energy Lithium-Ion Cells In lithium-ion cell design, one of the most critical relationships shaping performance is the link between anode porosity and energy density. As energy density increases, conventional design logic suggests reducing anode porosity to pack more active material into the … Read more
A look at hot versus cold roll calendering, why we might use hot vs cold and impact on electrodes. This post has been built based on the support of and sponsorship from: Resonate Testing Ltd, Quarto Technical Services, Eatron Technologies and About:Energy The quality and repeatability of the resultant cells will also be dependent on the uniformity of the roll temperature. … Read more
So what is the optimum calender roll temperature versus chemistry? We looked at a number of papers to offer an initial roll temperature and reasoning behind it. This is not extensive and as we have seen there are a number of other aspects that need to be considered such as energy use, LCA and capital … Read more
Burrs and wavy edges on cell electrodes can have serious consequences up to and including an internal short-circuit and thermal runaway. Hence it is important to understand the slitting process and under what conditions burrs and waviness occurs. Slitter Cutting Control Parameters There are basically three slitter cutting control parameters for the shear cut method, … Read more
AION Engineering INC Calendaring is a crucial step in lithium-ion battery manufacturing, where electrodes are compressed to reduce porosity and increase density. Optimizing this process directly impacts the performance, longevity, and efficiency of the final cell. Why Calendaring Matters The primary goals of calendaring are: Effectively, proper calendaring ensures a balance between mechanical stability, electrochemical … Read more
