KERI Tackles the Key Challenge in Lithium-Sulfur Battery Technology, Paving the Way for Urban Air Mobility
- Researchers at the Korea Electrotechnology Research Institute (KERI) have addressed the formation of lithium polysulfides during the operation of lithium-sulfur batteries, a major hurdle that has prevented their commercialization.
- KERI’s pioneering approach combines single-walled carbon nanotubes (SWCNTs) with oxygen functional groups to enhance the stability and efficiency of lithium-sulfur batteries.
- The innovative interface allows for better control of the dissolution and diffusion of lithium polysulfides, reducing the loss of the active material in the battery – sulfur.
- Uniform, smooth electrode surfaces can be achieved through the unique properties of SWCNTs and oxygen functional groups, enabling the production of large-area, high-capacity flexible batteries.
- In testing, the newly developed prototype displayed exceptional capacity retention, maintaining over 85% of its original charge even after enduring 100 charge-discharge cycles.
- Industries such as urban air mobility, electric vehicles, and aerospace sectors have a growing demand for advanced and safe battery technologies.
- KERI’s innovative solution may provide the transformative leap forward the energy sector has been eagerly anticipating.
- KERI’s success serves as an exemplary showcase of how perseverance, creativity and innovation converge to unlock new possibilities in energy storage.
- The institute is poised to redefine energy solutions and drive innovation forward in this exciting and vital field of technology.
- Dr. Park Jun-woo’s team is not just laying the groundwork for future development; they are designing the future of energy storage itself.
