Our advanced energy storage research focuses on developing next-generation lithium–sulfur and aqueous zinc batteries that offer high capacity, long-term stability, and improved safety. By integrating innovative electrode architectures, optimized electrolytes, and tailored material interfaces, we enhance the energy density and cycling performance of these systems. This work enables the creation of cost-effective, scalable storage solutions capable of supporting intermittent renewable energy, stabilizing power grids, and enabling wider deployment of clean-energy technologies. Through these efforts, we contribute to building a more reliable, sustainable, and resilient energy future.
