It can be concluded that the nanosecond fiber laser has a bigger processing thermal influence to the soft materials like the battery electrode. Its laser beam is easy to cause big damage to the processing area and the surrounding area in processing. However, the picosecond fiber laser will bring fewer damages to the close areas in processing. It is feasible to employ the picosecond fiber laser to replace the traditional processing mean and the nanosecond laser in processing the electrode of the lithium-ion battery.
