This is an introduction of a case of penetrating polyphenylene sulfide (PPS) using a sheet laser machine.
Drilling was performed on PPS (t = 25 μm) with a hole diameter of 18 μm, a pitch of 155 μm (parallel type), and an aperture ratio of 1.1%. WIRED Co., Ltd.
This is an introduction of a case of penetrating copper (Cu) with a sheet laser machine.
Drilling was performed on Cu (t = 10 μm) with a hole diameter of 6 μm, a pitch of 30 μm (staggered arrangement), and an aperture ratio of 8.5%. WIRED Co., Ltd.

Through joint research with Yamagata University, a national university corporation, we have succeeded in prototyping a battery that enables lithium-ion predoping in a simple manner and greatly reduces irreversible capacity in the SiO negative electrode with laser perforation.Wired Co., Ltd.
To actually compensate for the "irreversible capacity (i.e., active lithium loss)" normally observed in the first charge/discharge cycle of lithium-ion batteries (LIB), for example, caused by solid electrolyte intermediate phase (SEI) formation, so-called pre-lithiumization was applied to graphite anodes in laminated cells composed of three graphite negative electrodes and three LFP (lithium iron phosphate) positive electrodes. WIRED Co., Ltd.
Degraded charge / discharge capacity cells in speed performance tests of lithium iron phosphate (LFP) positive electrodes with different loads of active material on both sides of the stacked current collectors were not actually observed at low C rates. did. However, rate performance data obtained at high C rates showed that imbalances in the loading of active positive electrode materials on both sides of the Al current collector caused significant volume reduction. It was found that using picoseconds to laser drill the positive electrode with a micrometer-sized grid pattern can prevent the capacitance loss observed at high C rates. Wired Co., Ltd.
