Abstract
Extreme fast charging of lithium-ion batteries requires simultaneous improvements in ionic transport, electronic conduction, interfacial stability, and thermal safety. This lecture presents two complementary research routes for engineering functional battery materials. The first route focuses on polymer-based components, including poly(vinylidene fluoride)-based electrolyte membranes modified with nanoclay, ZnO, SiO₂, and polymer additives, as well as electrospun nanofiber separators designed to improve electrolyte uptake, ionic conductivity, porosity, and thermal stability. The second route addresses electronic-transport limitations through the incorporation of low-loading, flash-synthesized graphene-like carbon into nickel-rich layered-oxide electrodes. The resulting conductive carbon network reduces electrode polarization and promotes more homogeneous electrochemical reactions during high-rate charging without substantially increasing the inactive material content. Although developed as distinct material systems, these two approaches address interconnected limitations governing fast-charging performance: ion transport through electrolyte and separator components, and electron transport within composite electrodes. Together, the findings provide a broader materials-engineering framework for developing safer, more durable, and extreme-fast-charging lithium-ion batteries for electric mobility and high-power energy-storage applications.
