Research Interests
Professor Pol's extensive research background includes colloid and interfacial science, electrochemical-, materials-, chemical-, sustainable-, and environmental engineering. His current passion lies in electrochemical energy storage technologies, primarily the scalable design and optimization of electrode materials, separator designs and electrolyte discovery for lithium-ion, potassium ion, sodium-ion, lithium-sulfur and solid-state batteries with thermal safety aspects.
The Vilas Pol Energy Research (ViPER) is an experimental group dedicated to fulfill the knowledge gap required to advance the energy storage technologies. Utilizing advanced sonochemistry, solvent-free autogenic chemical reactions, hydrothermal synthesis and microwave irradiation techniques, a diverse range of innovative, multi-functional electrode materials are fabricated and tested for next-generation safer battery systems. Moreover, we perform a wide variety of characterization including structure, morphology, and composition on developed electrode materials to understand the fundamental chemistry with underlying formation mechanism. We closely work with national laboratories, industries, and university collaborators across the globe.
Our current efforts include:
(1) Understanding the origin of thermal runaway mechanism in Lithium-ion, Sodium-ion, Potassium-ion and all solid state batteries and developing scientific strategies to mitigate them.
(2) Synthesis and mechanistic elucidation of novel carbon architectures (nano, sub-micro and microspheres; macro, meso, and micro-structured carbons, nanotubes, graphene, and their metal and metal-oxide hybrids) for energy storage applications.
(3) Discovery and design of high-capacity anode, cathode and electrolytes materials with longer lasting, sustainable and safer battery chemistries. Exploration of innovative electrochemical cell geometries with enhanced mechanical, flexible, and lightweight properties.
(4) Development of the physio-electrochemical transport understanding in multi-scale porous microstructures and the relevant electrode degradation mechanisms over long cycle periods (in collaboration with prominent modeling groups).
(5) Minimize the interfacial impedance in all solid state batteries to enhance room temperature electrochemical performance via development of hybrid polymer/garnet based electrolytes and interfaces with electrodes.
(6) Applications of novel multi-functional hybrid materials developed at ViPER in the fields of super-capacitors, CO2 capture, bio-sensing, solar cells, lubrication additives, fuel cell catalysts, superconductors, optical, magnetic, and flexible polymer-based devices.
