Research output: Patent


The present disclosure provides a calorimeter device and an electrochemical system analysis method. The device includes a first thermo-electric gauge (TEG) and a first conductor thermally coupled to the first TEG, the first conductor comprising a first surface. The device may also include a second conductor with a second surface, the second surface facing the first surface, thereby forming a gap. The device may also include a second TEG thermally coupled to the second conductor and an adjustment mechanism attached to the second TEG, operable to modify a size of the gap between the first surface and the second surface. The method includes applying a plurality of electrical signals across an electrochemical system, determining, using a calorimeter, at least one rate at which heat is generated by the system, and determining at least one thermal characteristic of a component of the system.
