Measuring the chemical state of the battery components such as the cathode, anode, separator, electrolyte, contact layers and additives, at various stages of cycling, provides vital information about the electrochemical processes that occur during battery use. EAG offers elemental and molecular analyses using a number of different analytical tools to address this need. Moisture sensitive materials are extracted from cells in a moisture controlled environment and can be transferred to instruments for analysis without exposure to air or moisture.
