Multichannel Electrochemical Cell and Liquid‐Handling Dispenser for High‐Throughput Combinatorial Screening of Multicomponent Electrolytes for Advanced Lithium‐Ion Batteries

A high-throughput experimental setup, which includes a (i) closed-type 36-well multichannel electrochemical cell module, (ii) noncontact liquid-handling dispenser, and (iii) multielectrochemical analyzer installed within a temperature-controlled chamber, achieves a throughput of over 400 samples per week.

The performance requirements of Li-ion batteries as energy storage devices are continuously increasing. To meet these demands, optimizing the electrolyte composition, especially for expanding the operating temperature range of LiBs, remains a critical challenge. High-throughput experimentation represents an effective approach for accelerating the discovery of multicomponent electrolytes. However, most high-throughput experiment studies on battery electrolytes are focused on evaluating the battery performance at room temperature owing to the challenges of integrating temperature control systems. To address this limitation, this study introduces a high-throughput experimental setup composed of a (i) closed-type 36-well multichannel electrochemical cell module, (ii) noncontact liquid-handling dispenser, and (iii) multielectrochemical analyzer installed within a temperature-controlled chamber. This setup enables the preparation of multicomponent electrolyte additives in a combinatorial manner and the evaluation of battery performance with the prepared electrolytes across a wide temperature range, achieving a throughput of over 400 samples per week.
