Abstract
Exploration of increased electrode surface area through laser structuring is undertaken to improve performance. While nanosecond lasers offer cost-effective processing, femtosecond lasers achieve a minimal heat effect, excelling in precision. Prior research has mainly focused on changes in electrode performance due to the duration of laser pulses, with insufficient attention to optimizing processability. This study, therefore, aims to compare the processability of active material coating layer in LFP cathodes using both nanosecond and femtosecond lasers. The specimens were subsequently analyzed morphologically for processability using scanning electron microscopy (SEM). Differences in the cross-sectional morphology of LFP cathodes processed by the two types of lasers revealed that nanosecond lasers require a higher pulse energy density for material removal.
期刊介绍:
In 1985, the Journal of Science was founded as a platform for publishing national and international research papers across various disciplines, including natural sciences, technology, social sciences, and humanities. Over the years, the journal has experienced remarkable growth in terms of quality, size, and scope. Today, it encompasses a diverse range of publications dedicated to academic research.
Considering the rapid expansion of materials science, we are pleased to introduce the Journal of Science: Advanced Materials and Devices. This new addition to our journal series offers researchers an exciting opportunity to publish their work on all aspects of materials science and technology within the esteemed Journal of Science.
With this development, we aim to revolutionize the way research in materials science is expressed and organized, further strengthening our commitment to promoting outstanding research across various scientific and technological fields.
