High speed remote laser cutting of electrodes for lithium-ion batteries: Anode

► A 3D mathematical model of the high speed remote laser cutting of anode is developed. ► Simulation results present depth, width, and absorptivity variations during the laser cutting of the anode. ► Temperature distribution, melt pool geometry, melt pool flow, and composition distribution are examined. ► The cut surface, kerf width, and copper composition of the experimentally obtained sample are measured and compared. ► Computational and experimental results show an agreement.
