Engineers at the Hong Kong University of Science and Technology have pioneered a laser-driven technique that prints lithium-sulfur battery electrodes in a single step. The method synthesizes and assembles the electrode material in nanoseconds, replacing hours of conventional processing. Tests showed the laser-printed cathodes had strong conductivity, high sulfur utilization, and durability.

This technology could revolutionize battery production, enabling on-demand manufacturing of custom battery shapes while dramatically reducing factory throughput time. It also strengthens lithium-sulfur batteries’ potential as the next generation of high-energy storage.

Faster, flexible battery manufacturing could lower costs and meet soaring demand for EVs and grid storage. Companies adopting laser-printing techniques may gain a major speed and customization advantage in the competitive battery market.
