In the study of drying techniques for lithium batteries, the key point is the relationship between the amount of electrode dewatering and various dominant factors during drying.
The drying process of lithium-ion battery electrodes is one of the key processes for manufacturing electrodes with high surface homogeneity and is one of the most energy-consuming stages. The choice of the drying parameters has a significant impact on the electrode properties and the production efficiency.
In modern electrode manufacturing for lithium-ion batteries, the drying of the electrode pastes consumes a considerable amount of space and energy. To increase the efficiency of the drying process and reduce the footprint of the drying equipment, a laser-based drying process is investigated.
Although the aqueous-based cathode slurry is easy to be transferred to the current coating technology without extra cost, the sacrifice of capacity and cycle stability is not acceptable for battery production. Solvent-free manufacturing emerges as an effective method to skip the drying process and avoid the organic solvent.
The authors noted that the elec-trochemical performance of the electrode is not solely afected by slurry rheology, but that the drying parameters also play an important role in determining the electrochemical properties of the finished electrode. The optimal coating rate is sensitive to the specific drying mechanisms.
Liquid slurry is the most frequently used platform to fabricate the electrode materials mainly owing to its low cost and high processibility (Väyrynen & Salminen, 2012). The formulation and properties of electrode slurries determine the quality of the resulted electrode film.
