Lithium battery water drying

What is the drying process of lithium-ion battery electrodes?

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.

Can lithium batteries be dried?

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.

How can laser-based electrode drying improve the efficiency of lithium-ion batteries?

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.

Does water affect lithium ion batteries?

With the ongoing development of producing high-quality lithium-ion batteries (LIB), the influence of moisture on the individual components and ultimately the entire cell is an important aspect. It is well known that water can lead to significant aging effects on the components and the cell itself.

Can a convection dryer dry lithium-ion batteries?

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.

How does drying rate affect battery performance?

According to Jaiser et al., high drying rates enhance binder migration, which reduces the adhesion between the anode and the current collector [ 9 ]. This reduction negatively impacts the performance of the battery and can even lead to the delamination of the anode.
