Our research paper has been published in Electrochimica Acta

The “Development of a Roll-to-Roll High-Speed Laser Microfabrication Machine for Through-Hole Anode and Cathode Fabrication of Lithium-Ion Batteries” uses a laser + roll-to-roll device capable of forming through holes in thin electrodes at a rate of 100,000 per second.
The positive electrode of lithium iron phosphate and the negative electrode of graphite with that device, demonstrated higher rate characteristics than the unprocessed cathode and anode.

Ultra-high-speed laser drilling: 100,000 holes drilled per second

The unique optical system GHS (Grand Helical Scan) achieves ultra-high-speed drilling by synchronizing with high-speed web handling technology. High-speed hole processing of 100,000 holes/second has been achieved on PPS film that is transported at high speed from roll to roll. This technology does not select materials such as aluminum, copper, and resin film that are conveyed by Roll to Roll. 　Wired Co., Ltd.

An improved pre-lithiation of graphite anodes using through-holed cathode and anode electrodes in a laminated lithium ion battery

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.

An Improved High-rate Discharging Performance of “Unbalanced” LiFePO4 Cathodes with Different LiFePO4 Loadings by a Grid-patterned Micrometer Size-holed Electrode Structuring

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.
