  • Patent number: 12259348
    Abstract: Methods, systems, and apparatuses for multichannel, matrix-based testing of electrochemical materials are described herein. The system provides an electrochemical testing apparatus that consists of a bottom block having a first array of N×M receiving wells, and a top block with a second array of N×M chambers, with each of the N×M chambers having an electrical connector. The method involves inserting, into a number of the first array of N×M receiving wells, one or more electrochemical compositions to be tested. The method then involves closing the top block onto the bottom block. When the top and bottom blocks are closed, the N×M receiving wells and N×M chambers are aligned, thereby forming N×M testing cells. Finally, the method involves measuring one or more properties of the electrochemical composition inserted in the plurality of the N×M receiving wells.
