Research
We develop, synthesize and characterize materials with the goal of improving all-solid-state lithium-ion batteries. We are interested in carrying out interfacial studies of materials to faciltate the optimization of our solid-state system.
​
Our primary focus is on the:
-
Synthesis of high-energy cathode materials for electric vehicles, including conversion-type cathodes with high gravimetric energy density (500+ Wh/kg)
-
Understanding cathode and composite polymer solid-solid interactions
HIGH-ENERGY CATHODE MATERIALS
Attaining the full potential of lithium-ion batteries requires further advancement of electrode materials with greater capacity and good efficiency. Next-generation cathode material is important for the development of batteries with faster charging and longer battery life.
​
Our work explores and assesses the viability of promising compositions of materials such as iron-based compounds as cathode materials.

COMPOSITE SOLID POLYMER ELECTROLYTE
Substituting flammable liquid electrolytes with solid electrolytes offers many advantages like safety but faces many challenges in part due to the complexity of lithium. New electrolyte materials with stable interfaces with lithium are necessary to meet the energy demands.
​
Our work focuses on composite solid polymer electrolytes with the goal of a flexible interface and good ionic conductivity.

IN-SITU POLYMERIZATION SOLID-STATE BATTERIES
Many solid electrolytes have the disadvantage of having lower conductivity than liquid alternatives partly due to the lack of wetting in the battery. Ion flow within the cathode, which is not as conductive as the composite polymer electrolyte, would need to be facilitated to improve battery performance.
​
Our work explores the addition of our composite polymer material into the cathode through in-situ polymerization.​​
