A version of the two-electrode titanium battery test cell with a top port for a standard reference electrode. It accepts standard Ø6 mm reference electrodes such as Ag/Ag⁺, Ag/AgCl, saturated calomel (SCE), Hg/HgO and Hg/Hg₂SO₄, so you can choose the reference that suits an aqueous or non-aqueous electrolyte. The reference electrode is not included and can be ordered separately from our reference electrodes. In a three-electrode measurement the reference electrode lets the anode and cathode potentials be tracked separately, so you can tell which electrode limits cell performance and detect effects such as lithium plating or electrode polarization.
The body is high-purity titanium; the inner insulator is PEEK and the terminals are gold-plated copper. Chemically resistant O-rings and a screw-down lid keep the cell gas-tight, so it can be assembled in a glovebox and then tested outside. After testing, the cell is easily disassembled and cleaned without damaging the sample, so electrodes can be recovered for post-mortem analysis. The separator is supplied by the user.
