Calender Roll Temperature versus Chemistry

roll temperature and force schematic image

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

Comparing Cell Energy Density of Two Chemistries

This case study will highlight the importance of reporting new electrode active material performance parameters in full cell architectures. It will also discuss the need to understand the limits of different cell chemistries, and why any extrapolation of future performance must take into account the physical realities of the materials. The performance of electrode active … Read more

Lithium Sulfur Challenges

Lithium sulfur is perhaps the most mature of the ‘beyond Li-ion’ battery chemistries with a potential energy density of >600Whkg-1. Also with the potential for substantially reduced costs and improved safety. However, a number of challenges mean that cycle life has been poor. Hence the potential attracts attention and much needed research at the fundamental … Read more
