1. A method for electrochemical testing, the method comprising:
providing an electrochemical testing apparatus comprising:
a bottom electrochemical block comprising a first array of N×M receiving wells; and
a top electrochemical block comprising a second array of N×M chambers, each of the N×M chambers comprising a top electrode and a bottom electrode, and a spring positioned between the top electrode and the bottom electrode, wherein the bottom electrochemical block includes internal channels interconnected to the first array of N×M receiving wells;
inserting, into a plurality of the first array of the N×M receiving wells, one or more electrochemical materials to be tested;
closing the top electrochemical block onto the bottom electrochemical block, wherein when the top and bottom electrochemical blocks are closed, the N×M receiving wells and N×M chambers are aligned thereby forming N×M testing cells;
measuring one or more properties of the electrochemical materials inserted into the plurality of the N×M receiving wells; and
prior to measuring the one or more properties of the electrochemical materials, evacuating air from the internal channels and the top and bottom electrochemical blocks using a vacuum source.
