“Lithium-ion batteries today are reaching their theoretical energy limits. To overcome these limits, my team works on next-generation sodium- and magnesium-ion batteries, which can offer higher energy density and/or lower cost due to the different material chemistries. Recently, we developed one of the world’s best-performing sodium-sulfur battery operating over 1000 cycles at room temperature.
We are currently developing magnesium-sulfur batteries with even higher energy density and improved safety. These advanced batteries can be used to power both stationary and electromobile applications for a sustainable energy future.”
Dr Seh Zhi Wei is a Senior Scientist at IMRE. Dr Seh’s research interests lie in the design of new materials for energy storage and conversion, and he is widely recognized for designing the first yolk-shell nanostructure in lithium-sulfur batteries. Dr Seh has published in many top journals such as Science, Nature Energy, Nature Materials, Nature Communications, Nature Catalysis, and Nature Machine Intelligence. For his research achievements, he also received numerous awards including Vebleo Fellow Award, Ten Outstanding Young Persons, Emerging Investigators, Singapore NRF Fellowship, Innovators under 35 Asia, MRS Graduate Student Award, and A*STAR National Science Scholarship.
