Can laser cutting be used in battery manufacturing?
For laser cutting of electrodes a high degree of process readiness level is achieved, and commercial ns-laser cutter systems adapted to battery manufacturing are available and can be introduced in cell manufacturing. Nevertheless, laser cutting will be further developed regarding next generation of batteries using the thick-film concept.
How can laser processing technology improve battery manufacturing?
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.
Can laser-induced forward transfer be used to manufacture lithium-ion micro-batteries?
For the fabrication of thick-film electrodes with small lateral resolution, printing technologies such as laser-induced forward transfer (LIFT) are appropriate and even suitable for the manufacturing of a complete all-solid-state lithium-ion micro-batteries .
Why is ultrafast laser cutting of electrodes important?
Ultrafast laser cutting of electrodes offers improved cut edge qualities, less debris formation, and an improved ablation efficiency, which will be essential for a new electrode cutter generation. The processing speed of laser drying of electrodes seems to be a main drawback.
Can laser micro-structuring improve lithium ion diffusion kinetics?
In recent research from Mangang et al. it could be proven that the laser micro-structuring of thick-film LFP electrodes leads to an increase of the chemical diffusion coefficient, i.e. the lithium-ion diffusion kinetics could be significantly improved by increasing the active surface area due to laser structuring.
Can laser-assisted thermal treatment of lithium-ion cells be applied?
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.
