Combinatorial electrode array for high-throughput evaluation of combinatorial library for electrode materials

Abstract Our combinatorial robot system is able to automatically make a combinatorial library, which comprises (n×n) samples synthesized in the wells on a platinum reaction plate. An electrode array was developed for the high-throughput evaluation of the library. It has multiple counter electrodes, and its attachment to the library forms (n×n) electrochemical cells, which are operatable individually. In case of n=4, the evaluation was completed within 3 h, indicating that the combination of our robot system and our electrode array is very efficient for the exploration of new electrode materials.
