Integrated Combinatorial Synthesis, Characterization, and Test Platform for Lithium-Ion Battery Cathode Materials

An integrated combinatorial synthesis, characterization, and testing methodology and platform is proposed and developed for high-throughput exploration of Li-ion rechargeable battery cathode chemistries. This article describes the design of the platform’s combinatorial synthesis part and its prototype performance. A key design element is a multi-gear powertrain with a unique milling-force adjustable pestle that ensures high compatibility with varying types of electrode materials. To demonstrate the prototype, LiNiO₂ was prepared via a solid-state route under various operating conditions. We evaluated the effects of processing parameters, including milling force and mixing speed, on the synthesized electrode’s physical properties and electrochemical behavior.
