Hong Kong University of Science and Technology (HKUST) researchers have designed a groundbreaking single-step printing technique to accelerate the manufacturing of lithium-sulfur (Li-S) batteries.
Led by Mitch LI Guijun, PhD, assistant professor at the university’s integrative systems and design division, the team developed the high-speed laser-induced conversion process that integrates multiple complex steps.
Traditionally carried out separately under varying conditions and over extended periods, these stages are now completed in a single, continuous nanosecond-scale operation, enabling faster, more efficient fabrication of integrated sulfur cathodes without compromising precision or performance.
Combining the typically time-consuming processes of active material synthesis and cathode preparation into a rapid conversion, the technique is poised to transform industrial-scale production of printable electrochemical energy storage systems.
