Our research
Our lab focuses on fundamental and applied electrochemistry to drive advancements in next-generation energy storage solutions. We specialize in studying the intricate interfacial phenomena, novel material design, and cell performance, with the goal of developing safer, high-efficiency batteries for modern applications. From Na-ion batteries to aqueous zinc-based systems, our work aims to solve key challenges in the energy storage field by dissecting the chemical and electrochemical processes that occur within a cell.
Why Focus on Electrochemical Interfaces and Advanced Battery Materials?
Battery efficiency and longevity hinge on the interactions occurring at the electrode-electrolyte interfaces. Studying these interfaces closely allows us to observe the formation of protective layers, such as the Solid Electrolyte Interphase (SEI), and to understand degradation mechanisms that would be invisible in broader analyses. Just as observing the cellular structures in detail unlocks insights into life sciences, focusing on the atomic and molecular levels of batteries enables us to craft materials that are more robust, stable, and effective for long-term energy storage.
Through these focused studies, we address fundamental limitations in battery chemistry and contribute to safer, longer-lasting, and environmentally friendly energy solutions.

Electrode-Electrolyte Interface Engineering
Our lab investigates interfacial processes crucial for enhancing battery durability and performance. By examining phenomena like nucleation, growth, and SEI formation, we aim to minimize side reactions, particularly those leading to hydrogen evolution in aqueous batteries and dendrite formation in metal batteries. We use advanced in-situ and ex-situ methods to visualize and quantify these processes, enabling precise control over interfacial stability.

Focusing on aqueous zinc metal batteries, we work to optimize the electrolyte formulation and electrode stability to mitigate side reactions and prolong cycle life. We examine zinc anode dissolution, hydrogen evolution suppression, and electrolyte optimization to enhance safety and energy density, making aqueous systems more viable for large-scale storage.
Innovative Electrode Materials for High-Performance Li-ion and Na-ion Batteries
In designing anodes that meet the demands of modern energy storage, we develop and characterize materials ranging from inorganic to organic to hybrid organic-inorganic systems to composite systems. These materials are evaluated for high capacity, cycling stability, and compatibility with various electrolytes to boost the energy density and lifespan of Li-ion and Na-ion batteries.
Decoding Battery Mechanisms Through Post-Cycling Characterizations
​
We conduct in-depth post-cycling investigations to decode the intricate mechanisms governing battery performance. By probing changes in electrode materials, electrode morphology, tracking SEI evolution, and identifying electrolyte decomposition pathways, we uncover fundamental interfacial and structural dynamics. These insights provide a scientific foundation for material optimization and electrode design, driving the development of next-generation energy storage systems with enhanced durability and efficiency.
Advanced Electrochemical Analysis and Characterization Techniques
Our lab utilizes an array of electrochemical methods, such as cyclic voltammetry (CV), galvanostatic intermittent titration technique (GITT), potentiostatic intermittent titration technique (PITT), and scanning electrochemical microscopy (SECM). These techniques allow us to measure charge transfer kinetics, diffusion coefficients, and interface stability, providing insights into the mechanisms that govern interfacial electrochemistry.
