Batteries are among the key energy storage technologies for powering electronics, transportation and grids. The demand for lighter devices and safer, longer-duration storage continues to fuel the need for battery innovation – designing new materials and battery systems, understanding how they function and, ultimately, developing scalable processes to manufacture them. However, making battery materials and systems with the required capacity, power, lifespan, and safety is nontrivial, often hindered by the practical engineering challenges encountered when optimizing the intercorrelated processes involved in synthesis, processing, benchmarking, and upscaling.
In this presentation, we will share our research in in situ spectroscopy-guided design and scale-up of cost-effective process technologies for manufacturing next-generation cathode active materials (CAMs) for Li-ion and Na-ion batteries, bridging the gap from lab innovations to pilot-scale production. Alternative to the traditional
trial and error, we employ a science-based, data-driven approach that utilizes
in situ spectroscopy characterization and multiple modeling to tackle complex engineering challenges [1-5]. With specific examples, we will show how this approach enables the development of low-cost, scalable processes for producing CAMs with optimized structure, morphology and surface properties to meet multifaceted performance needs. We conclude by discussing emerging opportunities in digitalization of process design to close the loop from lab discovery to industrial manufacturing.
