Challenges and Opportunities for Large‐Scale Electrode Processing for Sodium‐Ion and Lithium‐Ion Battery

Julian Klemens,
Ann‐Kathrin Wurba,
David Burger
et al.

Abstract: Sodium‐ion batteries are an emerging technology that is still at an early stage of development. The electrode processing for anode and cathode is expected to be similar to lithium‐ion batteries (drop‐in technology), yet a detailed comparison is not published. There are ongoing questions about the influence of the active materials on processing parameters such as slurry viscosity, coating thicknesses, drying times, and behavior during fast drying. Herein, the expected drying time for the same areal capacity of … Show more

“…Drying rates and the associated production times are of great interest for the processing of electrodes. Higher drying rates (HDRs) can lead to different electrode properties [39, 46, 5962] but have an advantage over lower drying rates (LDRs) in terms of faster production times. Even the LDR when, for example, slow drying an electrode under ambient conditions in the laboratory also reflects the limiting case of NTUi,normalg0${\mathrm{NTU}}_{i,{\mathrm{g}}} \to 0$ and is described by gas‐side controlled drying, which increases the importance of this drying case.…”
