My research is centered on leveraging innovative techniques such as additive manufacturing and laser processing to design novel battery components that significantly enhance performance, improve cyclability, and increase the capacity of various battery chemistries. This includes a focus on solid-state batteries, anode-free designs, and advanced Li-ion technologies. By exploring these cutting-edge methods, I aim to optimize the efficiency, stability, and scalability of energy storage devices, driving advancements in next-generation battery technologies for a wide range of applications.
