Relationship between opening conditions and reaction temperature and Li+ ion predorp velocity on the electrostatic foil in laminated graphite/perforated electrolyted foil negative electrodes
When the lithium iron phosphate (LiFePO4, LFP) positive electrode was drilled with a picosecond pulse laser, high-speed discharge could be maintained. WIRED Co., Ltd.
Improvement of high-rate charging/discharging performance of a lithium ion battery composed of laminated LiFePO4 cathodes/ graphite anodes having porous electrode structures fabricated with a pico-second pulsed laser
To improve the fast charge / discharge performance of the laminated lithium iron phosphate (LiFePO4) positive / graphite negative electrode cells, a picosecond pulsed laser was used to form micrometer-sized through holes on the electrode surface. Wired Co., Ltd.
Relationship between Hole Design on Anode Electrode, the Reaction Temperature and the Rate of Li+ Ion Pre-doping Reaction to Porous Laminated Graphite Anodes
In recent years, in order to improve the performance of secondary batteries, it is strongly desired to improve the charge / discharge capacity of lithium-ion secondary batteries (LIBs) and the performance of sulfur batteries and air batteries, which are considered to be next-generation batteries, to the practical level. It is rare. While various materials are being developed, we believe that it is necessary to establish a lithium ion (Li +) pre-doping method as a basic technology to take the performance of such current secondary batteries to the next step. ing.

Improvement of Rate Performance of LiFePO4 Cathode with Porous LiFePO4/Activated Carbon Hybrid Electrode Structure
The electrodes produced by forming an LFP layer and an AC layer on each side of the Al current collector foil and then drilling through holes with a laser have a higher discharge capacity at higher current densities than conventional electrodes without holes. It was clarified that the decrease was small and the discharge capacity retention rate was high. Wired Co., Ltd.
