Flexible Li-S battery
Li-S batters offer very high theoretical energy density, however, it still suffers from its shuttle effect and continuous lithium dendrite formation.
Soluble Lead Flow Battery
Modify electrode or electrolyte, to improve the kinetics hence extending its cycle life
When flash sintering occurs, the grain boundaries continue to grow, increasing the conductivity of materials. During this period, the redox-reaction will occur.

Determination of SoH
State of Health (SoH) is one of the most relevant data of battery management. The amount of data accumulated is suitable to be studied by using machine learning
Previous Research Projects
Advantageous in high rate charge/discharge as an energy storage device. We believed it could potentially solve the issue of slow charging rate associated with EVs. We focus on using carbon fiber (CF) to achieve high mechanical strength and high performance supercapacitors for EV applications.
Methanol Fuel Cell Architecture
Methanol fuel cells convert chemical energy of methanol into electric power. On the other hand, air is required as an oxidant to complete the reaction. We developed air-breath type methanol fuel cell to simplify its architecture and reduce the cost.
Modeling of LiFePO4 Battery Pack
Burning or explosion of batteries is usually induced by heat accumulation and ultimately thermal runaway. Coupled model framework considering energy balance, mass balance and electrochemical reaction kinetics are developed to simulate discharge behavior and temperature distribution of LFP batteries and battery packs.
Lithium Sulfur Battery Modelling
Li-S is considered as next generation battery for portable applications. However, the technology faces sever challenges due to the lack of understanding of the Li-S system. A multi-scale model framework from ab initio to continuum level is developed to gain insight into underlying physics of the lithium sulfur battery.
Solid Oxide Fuel Cell
Transition metal perovskite oxides is advantageous in their ability to accommodate oxygen vacancies, while preserving the lattice structure for electron transport. We utilize the smoothed-boundary model framework to implement such a dual-path model to simulate ion transport in perovskite oxide materials.
Li-Metal Dendrite Inhibition
Dendrite formation in lithium metal battery hampered its realization. We develop an electrochemical model and implement a linear stability analysis to investigate the effects of elastic separators on dendrite growth kinetics. The onset of morphological stability is found to be dependent on the shear modulus of the separator and the lithium electrode.
Fuel Cell Powered Plant Factory
A micro plant factory coupled with an auxiliary fuel-cell power is established in our group. The goal is to harvest the power as well as recycle CO2 exhaust for use in the plant factory. In addition, we try to find the optimal mode of coupled operation of plant factory and fuel cell.
Plant Microbial Fuel Cell for Plant Factory
In a plant factory, the nutrient for vegetables is supplied by the flowing nutrient solution. However, such solution degrades after long term operations. We design and develop a plant microbial fuel cell suitable to the plant factory. The goal is not only to generate electricity but also to purify the nutrient solution with the fuel cell.
