« A recent battery manufacturing project—affectionately called BatMan—has developed a novel laser patterning process to microstructure of battery electrode materials. Funded by DOE’s Advanced Materials and Manufacturing Technologies Office, this project brings together expert minds from the National Renewable Energy Laboratory, Clarios, Amplitude Laser, and Liminal Insights. This revolutionized manufacturing process could unlock significant improvements to electrified transportation, leading the charge toward a brighter and more sustainable future. (…) Researchers used an Amplitude Laser femtosecond laser system with high-speed galvanometer-controlled scanning optics for the laser ablation, working closely with the Amplitude team to achieve precise control of the laser based on position, power, frequency, and number of pulses. NREL researchers led by Donal Finegan fine-tuned those parameters to optimize the process.

“Our collaboration with NREL helped integrate the laser into their existing research capabilities to support the BatMan project goals,” said Quentin Mocaer. “We also received valuable insights into how future system designs and new technologies could further improve this process at an industrial scale.”

Results in brief:

The team National Renewable Energy Laboratory researcher Nathan Dunlap has demonstrated superior FAST-CHARGE PERFORMANCE with nearly 100% more capacity after 800 cycles for electrodes patterned with our lasers. It also shows great improvement in wetting time, beneficiating from channels allowing better Li ions propagation.

Cost-analysis simulations using the Battery Performance and Cost Model indicate industrial adoption would require minimal capital and operational investment, resulting in only ≈ 1-2 $/kWh for a 50 MWh factory. As commercially available, industrial, ultrafast lasers approach the 1 kW average power threshold, there is interest in realizing the above-described benefits to LIB performance in high-throughput electrode manufacturing lines.

The research group of laser-matter interaction at the Institute of Intense Lasers and Applications (CELIA) at the University of Bordeaux, France, has explored a new glass micro-drilling method using a femtosecond laser in GHz-burst mode.

Publishing in the journal International Journal of Extreme Manufacturing, the research team used a femtosecond laser from Amplitude operating in the GHz-burst regime to study a new glass micromachining method which allows for drilling taper-free, elongated holes with smooth inner walls without any cracks in the glass. Usually, laser drilling with standard single femtosecond pulses results in tapered holes of strongly limited length and rough inner surface.

This new laser-matter interaction regime makes it possible to directly drill holes of high aspect ratio in one single step without any chemical etching. The choice of the laser-burst parameters was revealed to be very important in order to achieve an outstanding micromachining quality of the machined structures. The femtosecond laser GHz-burst mode could pave the way for new applications such as microelectronics where silicon interposers are likely to be replaced by glass interposers.
