Research Interest
My research interests encompass the development and advancement of various energy storage systems, including electrochromic batteries, zinc-ion batteries, and photo batteries. I am committed to optimizing these technologies to improve energy density, stability, and overall efficiency while exploring their multifunctional applications. This work emphasizes innovations in materials science, such as electrochromic materials for integrated energy feedback, zinc-based chemistries for safe and sustainable storage, and photo-responsive materials for energy harvesting. Through these efforts, I aim to contribute meaningfully to the progression of reliable, environmentally sustainable, and versatile energy storage solutions.
I am actively researching electrochromic batteries, concentrating on integrating energy storage with visual feedback mechanisms. My work involves optimizing electrochromic materials to improve cycling stability and energy density, while exploring novel applications such as smart windows and adaptive displays. By examining advanced materials like transition metal oxides and conductive polymers, I aim to enhance the performance and efficiency of electrochromic batteries, tackling key challenges related to color stability, response speed, and scalability. My research supports the expanding role of ECBs in sustainable energy and innovative, aesthetically functional technologies.
Electrochromic battery
Zinc-ion battery
I am researching zinc-ion batteries with an emphasis on improving their energy storage capacity and long-term stability. My work addresses key challenges such as dendrite formation, cycle life, and energy density, which are essential for practical zinc-ion battery applications. I am developing V- and Mn-based cathodes using various approaches, including doping and lattice engineering, to enhance performance. Additionally, I am focused on stabilizing the zinc anode to reduce dendrite growth by applying protective coatings or adding electrolyte additives. My goal is to advance safe, cost-effective, and environmentally friendly energy storage solutions.
