Principle of new drying technology for lithium batteries

How does drying a lithium ion battery affect its performance?

Drying the electrode is a crucial process in the manufacture of lithium-ion batteries, which significantly affects the mechanical performance and cycle life of electrodes. High drying rate increases the battery production but reduces the uniformity of the binder in the electrode, which causes the detaching of the electrode from the collector.

Is laser drying a complementary process step in the production of lithium-ion batteries?

Moreover, the use of laser drying as a complementary process step in the production of lithium-ion batteries needs to be investigated. This aims at the further reduction of the residual moisture reabsorbed after the actual electrode drying process.

Can dry process technology replace wet process in lithium-ion batteries?

As one of the highly promising electrode manufacturing technologies, the dry process technology is expected to replace the wet process currently used on a large scale in state-of-the-art commercial lithium-ion batteries. However, a number of challenges remain before this new technology can be commercialized. 4.1. Study of Dry Mixing Systems

Why do lithium ion batteries need dry electrodes?

The performance of lithium-ion batteries depends greatly on the composition and microstructure of the electrodes. Unlike SC electrodes, dry electrodes can improve area capacity and other electrochemical properties by changing the microstructure and morphology.

Why do lithium-ion batteries need a vertical drying alignment?

Due to the long drying lengths, vertical drying alignments are only applicable to research and pilot plants with low band speeds. Within the value chain of lithium-ion battery cells, the energy consumption during the drying process corresponds to about one fifth of the total energy consumption .

Can laser drying be used for lithium ion batteries?

Excerpt of potential areas of application of laser drying within the manufacturing chain of lithium-ion batteries During the drying process, most of the solvent is evaporated immediately at the beginning . Thus, secondary drying or post-drying may be required after processing .
