Reduction of irreversible capacity by laser drilling and predoping to SiO negative electrodes for lithium-ion secondary batteries (LIB)
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.
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.
