Research Areas

Focus Area 1: Electrolyte Development

Importance: Electrolytes connect the two separated electrodes with a liquid or solid phase by providing ion transport channels between them. The properties (wettability, viscosity, melting point, ionic conductivity, thermal stability, etc.) of an electrolyte and its compatibility with both electrodes (anodic stability, cathodic stability, chemical stability, mechanical stability, etc.) determine the performance of a battery. 

Topics

Approaches: Researcher-driven, Data-driven

Applications: (Anode-free) Lithium-metal Batteries, Lithium-ion Batteries, Na Batteries, All Solid State Batteries

Focus Area 2: Surface Engineering

Importance: Surface engineering is widely reported to improve the stability of electrodes, protect against unwanted reactions with electrolytes, and increase the electronic and ionic conductivity of the electrode. The challenges lie in selecting appropriate coating materials with desired properties and applying the coating materials uniformly on the surface of battery electrodes with a nanometer-scale thickness.

Topics

Approaches: Solution-based methods, Vapor-based methods (iCVD, oCVD).

Applications: (Anode-free) Li-metal Batteries, Lithium-ion Batteries, Na Batteries, All Solid State Batteries

Focus Area 3: Advanced Characterization

Importance: The development of advanced characterization tools provides us with pathways to understand the structure-property-performance relationship of materials and their interface. Such understanding is crucial to the development of new functional materials for developing next-generation renewable energy storage devices.

Topics

Approaches: In-house setup, collaboration with national labs.

Applications: (Anode-free) Li-metal Batteries, Lithium-ion Batteries, Na Batteries, All Solid State Batteries
