• Design and development of low-cost, high-energy and safe electrode materials (anode and cathode) for rechargeable Li/Na-ion Batteries.

Rechargeable Li-ion batteries (LIBs) are essential to modern society, powering devices like laptops and phones. Building on their success in portable electronics, researchers and industries are expanding their use to electric vehicles (EVs) and grid energy storage. Efforts are also focused on using more abundant sodium (Na) as an alternative to lithium (Li). To meet growing demands, developing LIBs and Na-ion batteries (NIBs) with higher energy density, longer life, improved safety, and lower costs is critical.

Among the key components of L/NIBs (anode, cathode, electrolyte, separator, binder, and current collectors), the anode and cathode often limit performance. Repeated charge/discharge cycles and high-voltage operations can cause failures like irreversible phase transformations, uncontrolled solid-electrolyte interface (SEI) formation, and particle cracking. These issues may lead to thermal runaway and rapid performance degradation, emphasizing the need for robust electrode materials.

Using advanced computational methods like Density Functional Theory, Molecular Dynamics simulations, and thermodynamic modeling, our research aims to:

  1. Uncover atomic-level causes of L/NIB failures, particularly in electrode degradation.
  2. Improve the performance of next-generation electrode materials, such as Co-free layered oxides, Li-rich oxides, LiSICON, NaSICON, and silicon/carbon-based anodes.

We focus on key phenomena in electrode materials, including:

  • Cationic and anionic redox mechanisms
  • Electrode-electrolyte interface interactions
  • Phase transformations
  • Ionic and electronic transport

This knowledge will guide the design of high-energy, durable electrodes. Collaboration with experimental research will complement these efforts as resources allow.

  • Physics and chemistry of semiconductor for energy-related applications.

Using advanced first-principles density functional theory (DFT)-based electronic structure calculations, we investigate the physical and chemical properties of defects and dopants in semiconductors, focusing on materials such as oxides (e.g., ZnO, TiO₂, CeO₂, WO₃, LiCoO₂, LiNiO₂) and kesterites (e.g., Cu₂ZnSnS₄) for energy-related applications like Li/Na-ion batteries and photovoltaics. Our research aims to understand how dopants and native defects influence key properties that impact the performance and functionality of these materials.

We specifically examine the role of defects and dopants in determining:

  • Ionic and electronic conductivity, crucial for charge transport in energy devices.
  • Band gap engineering, which affects optical absorption and electronic properties.
  • Charge localization, influencing carrier dynamics and defect stability.
  • Defect and dopant formation energetics, providing insights into material stability and reactivity.

Our analysis spans both the bulk material and surface/interface regions, as these areas critically affect device efficiency and stability. By uncovering the relationships between defects, dopants, and material properties, we aim to guide the development of semiconductors with optimized performance for energy storage and conversion technologies.
