- 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) have become an integral part of the modern society. It powers various modern electronic devices such as our laptop computers, mobile phones, etc. Inspired by its successful implementation and commercialization for portable electronic devices, academia and industries are now intensively trying to widen LIBs usage into larger scale applications such as electric vehicle (EVs) and grid energy storage. Further efforts also have been intensively made to utilize the much more abundance Na as an alternative to Li. Thus, the need of LIBs and Na-ion batteries (NIBs) with higher energy density, longer life cycle, safer and lower price is of utmost importance.
Of several major components of L/NIBs (i.e. anode, cathode, electrolyte, separator, binder, current collectors), both anode and cathode often become the performance-limiting factors. This is due to multiple deleterious physicochemical phenomena that both electrodes possibly suffer over repeated charging/discharging cycles (e.g. irreversible phase transformation, uncontrolled solid-electrolyte interface (SEI) formations, particle cracking, etc.). Those phenomena potentially lead to L/NIBs cell failure such as thermal runaway and rapid performance fading. Hence, rationale design of electrode materials that can withstand the aforementioned failures is important.
By means of state-of-the-art first-principles Density Functional Theory calculations, Molecular Dynamics simulation, and first-principles-based thermodynamics and statistical mechanics analysis our research objectives are two folds:
- understanding the atomic-level origins of L/NIBs failure mainly caused by the degradation of electrodes,
- performance improvement of next-gen electrode compounds (e.g., Co-free layered oxides, Li-rich oxides, LiSICON, NaSICON, Silicon/Carbon-based anode, etc.).
This will be done in terms of understanding multiple physicochemical phenomena in L/NIBs electrode materials such as:
- cationic and anionic redox mechanism,
- interface phenomena of electrode-electrolyte interaction,
- phase transformations in electrodes,
- ionic and electronic transport mechanisms.
The knowledge gained will be used as a guideline to design high-energy electrodes with more robust structure. Collaborative research with experiments will also be done whenever resources (viz., man and funding) are available.

- Physics and chemistry of semiconductor for energy-related applications.
We explore physical and chemical properties of defects and dopants in semiconductors such as oxides (ZnO, TiO2, CeO2, WO3, LiCoO2, LiNiO2, etc.) and kesterites (Cu2ZnSnS4) for energy-related applications (e.g., Li/Na-ion batteries and photovoltaics). Understanding the effect of dopants and native defects on technologically relevant properties such as ionic and electronic conductivities in these materials is crucial towards their utilizations. Our efforts focus on the determining electronic and ionic mobilities, band gaps, charge localization, and the behavior of defects and dopants inside the bulk and on the surface/interface area of those semiconductors.
