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.

How do you dry battery electrodes?

The starting point for drying battery electrodes on an industrial scale is a wet film of particulate solvent dispersions, which are applied to a current collector foil by slot-die coating. Conventional convective drying removes the solvent from the wet film and solidifies the layer as the drying time progresses ( Figure 1 ).

What is dry battery electrode technology?

Our review paper comprehensively examines the dry battery electrode technology used in LIBs, which implies the use of no solvents to produce dry electrodes or coatings. In contrast, the conventional wet electrode technique includes processes for solvent recovery/drying and the mixing of solvents like N-methyl pyrrolidine (NMP).

How does the dry process affect the structure of battery materials?

ORNL and industry partner Navitas Systems probed how the dry process affects the structure of battery materials and their electrochemical properties. Batteries generate energy as lithium ions travel between electrodes called the cathode and anode.

How does dry film production improve battery production?

The dry-film-production approach streamlines the manufacturing of LIBs by eliminating the traditional solvent mixing, coating, drying, and solvent recovery steps. This reduction in process complexity also results in significant energy and equipment expense savings. As a result, this has greatly improved the efficiency of battery production.

Is a scalable dry electrode process necessary for lithium based batteries?

Scalable dry electrode process is essential for the sustainable manufacturing of the lithium based batteries. Here, the authors propose a dry press-coating technique to fabricate a robust and flexible high loading electrode for lithium pouch cells.
