Laser manufacturing of 3D lithium-ion thin- and thick-film batteries was realized also by direct structuring of the active material , , , . With the electrode fabricated by laser ablation or modification, the 3D and high aspect ratio battery was completed.
Production of large-format lithium-ion batteries with laser-structured anodes. Laser-structuring of anodes improves discharge and charge rate capability. Extension of cyclic lifetime under fast-charging operation. Incremental capacity analyses reveal a reduction of lithium-plating.
Laser structuring of composite electrodes is one of the most promising approaches regarding battery performance improvement by the 3D battery concept and an increase of battery safety and production reliability.
Laser-assisted thermal treatment of active material for lithium-ion cells can be applied for thin and thick-film electrodes. The as-deposited thin-film material has in general not the proper crystalline battery phase and chemical composition.
Integration of laser processing technology into battery manufacturing will provide new impacts to process reliability, processing cost reduction, improved battery performance, and battery safety. Especially for HE batteries, wetting of the electrodes with liquid electrolyte is a critical issue.
Laser structuring can turn electrodes into superwicking. This has a positive impact regarding an increased battery lifetime and a reliable battery production. Finally, laser processes can be up-scaled in order to transfer the 3D battery concept to high-energy and high-power lithium-ion cells.
