Core Application Competencies
Welding
Cutting & Slitting
Surface Treatment
Precise, digitally controlled cutting with clean, crisp edges for slitting, notching, and separating applications.
Create laser drilled channels arranged in a hexagonal pattern to optimize the electrochemical properties of the electrode.
Zero contact welding with consistent results around complex shapes and angles with no blowholes.
Marking & Coding
Cleaning
Ablation
Apply permanent graphical marks and alpha- numeric codes on multiple surface types without consumable inks or powders.
Zero contact with micrometer precision to remove debris and over-processing residue.
Easily remove coatings from metal surfaces with micrometer precision for better conductivity.
Coating - Laser Structuring of Graphite Anodes Lithium-ion batteries (LiBs) containing structured graphite anodes show a significant performance increase in comparison to their unstructured counterparts. Furthermore, LIBs with structured electrodes exhibit an enhanced lifetime through the reduction of degradation effects such as Lithium plating. Laser structuring the elctrode can also allow for better diffusion of the electrolyte within the battery via capillary action, which can reduce production failures, can extend the battery lifetime, and can increase the battery capacity. Pulsed laser radiation has been proven to be a versatile tool for the introduction of diffusion channels into the electrodes with micrometer precision. Ultrashort-pulsed laser sources allow the selective ablation of electrode coatings with low heat input into the surrounding material. Laser drilled channels arranged in a hexagonal pattern optimize the electrochemical properties of the electrode. A picosecond laser, emitting laser pulses at 1064 nm with a typical length of 8 picoseconds combined with a high-precision scan head with galvanometer-driven mirrors and focused with an F-Theta lens onto the substrate.

Tailoring – Slitting, Separating The tailoring of electrode foils traditionally relies on mechanical cutting processes such as punching and blade cutting, which exhibit notable drawbacks, such as tool wear, metal layer smearing, and limited contour adaptability. Changing the shape of the electrode requires redesigning of the cutting tools, which increases costs. In contrast, laser cutting has emerged as a proven, efficient, and reliable manufacturing method, already utilized across industries. The distinct advantages of laser cutting, including a non-contact process, and high processing speed outweigh those of mechanical cutting. The simplicity and cost-effectiveness of digitally controlled laser cutting enables cutting geometry changes underscores its superiority over mechanical processes. Tailoring of battery foil can be divided into different types of cutting processes; notching, slitting, and separating. The most important evaluation parameter is the quality of the cut, which ideally should be burr-free and without spatter and melt deposits. Laser cutting has shown outstanding performance in terms of cutting speed, short processing times and flexible adaptation to desired geometries in a non-contact process.

Packaging – High Integrity Welds In the final step, cells are bundled into a package and often connected with a copper, steel, aluminum, or copper-aluminum composite bus bar. High integrity welds are needed to avoid blowholes that can cause battery failure. Novanta’s dynamic focusing module in 3-axis scan heads can be used from a single position to direct the laser beam at complex angles to ensure a solid weld. Combined with laser wobble technology the result is consistent, deep, spat-free welds.
