Abstract
Herein, an experimental setup comprised of a stationary convection dryer (Comb Nozzle Dryer) supplemented by a measurement for gravimetric drying curves is introduced. The drying process of anodes for lithium‐ion batteries is experimentally investigated and compared to modeling results, showing very good agreement for the investigated films. Heat transfer coefficients of the issued impinging nozzles are characterized and measured quantitatively and are used for the drying simulation of the gravimetric drying experiments. In situ temperature changes in the films are measured and presented using an infrared camera setup.
Highlights
Are very complex and based on single measurements, which is why further research is needed to establish new and easy ways to illuminate the drying process
Introduction further experiments and simulations investigate the drying process of lithium-ion batteries to predict its influence on cell per
Electrode adhesion as well as rate capability and capacity of model, concluding that half of the drying time is needed to the final cell decrease, when high instead of low drying rates are chosen for electrode drying.[1,2,3]
Summary
To record the film temperature over drying time with an infrared (IR) camera and to obtain gravimetric drying curves, electrode slurries were prepared using the same mixing procedure and paste composition for all the experiments in this work. Each measurement of a gravimetric drying curve was repeated at least three times
