Abstract

Li-ion batteries have revolutionized energy usage by providing efficient, portable, and reliable power sources for a wide range of applications. Still, their energy density, cost, safety, and resource constraints pose significant challenges for widespread applications in transportation and stationary storage. In fact, as the push for net zero emissions intensifies, the need for alternative technologies that are energy-dense and safer or cheaper, safer, and sustainable is becoming apparent. In this regard, lithium all-solid-state, Li-S, Na-ion, and aqueous rechargeable batteries have garnered tremendous research interest. However, the promise of these technologies hinges on the ability to overcome complex and intertwined chemical, structural, transport, interfacial, and corrosion challenges, which our research team aspires to address under scalable conditions toward the practical development of those technologies. This presentation will give a brief overview of some of our studies from the past couple of years.


From the development of benign electrolyte additives that suppress corrosion and associated deposition instability of the zinc electrode at low volume concentrations to decoding the zinc depletion mediated failure of the zinc anode and the origin and impact of the deleterious H+ - storage in a high-voltage cathode will be discussed on the development of aqueous zinc-ion batteries. On all-solid-state batteries, fundamental insights into the electro-chemo-mechanics of Li-In/Sn alloy anodes, overcoming interfacial stability issues of the NMC-type (LiNixMnyCozO2) cathode with sulfide solid electrolytes, and controlling microstructure toward obtaining highly conductive (>2 mS cm-1) halide solid electrolytes will be discussed. Finally, this talk will give a sneak peek into preliminary results from our collaborative work on 3D printing of solid polymer electrolytes and organosulfur polymers as sulfur hosts in Li-S batteries (SPARC project with Prof. Leena Nebhani, IIT Delhi). The presentation will showcase some of our research achievements and capabilities and highlight the prospect and direction of work for developing next-generation battery technologies toward embracing a renewable energy future.
