Conclusions Laser cutting allows an improved quality of cut surface and cutting speed during lithium-ion battery manufacturing processes. The advantages of laser cutting can be maximized by understanding the underlying physics during the laser cutting of electrodes for lithium-ion batteries.
High speed laser cuttings of electrodes for the lithium-ion battery using single mode fiber lasers have also been investigated by Patwa et al. . They illustrated the achievable highest cutting speed, the effect of the focus beam and the number of cutting passes.
Investigating underlying physical phenomena with numerical analysis provides significant advantages to fully utilize the remote laser cutting of electrodes for lithium-ion batteries. In this paper, a mathematical model of three-dimensional self-consistent remote laser cutting is presented for anode (graphite-coated copper) of lithium-ion batteries.
Lithium-ion battery performance is affected by cut surface quality during the electrodes' cutting process. Currently, die cutting and rotary knife slitting have been used to cut prismatic and cylindrical electrodes, respectively.
