Abstract
This study employs LiMn0.7Fe0.3PO4 cathodes as active materials, with electrochemical performance enhanced by laser structuring. Ultrashort pulse laser ablation combined with GHz bursts enables high-throughput fabrication of precisely defined 3D electrode structures. The laser parameters, such as peak fluence and burst length are optimized to assess their effects on the laser processing quality and ablation efficiency. SEM is applied to examine potential thermal modifications of electrodes. Half-cells with structured and unstructured electrodes are assembled and analysed regarding rate capability.
