Model: B001‑3 • Cell body material: PEEK • Conductive medium for connecting positive and negative electrodes: Glassy carbon electrode (GC‑Φ3) • Positive and negative electrodes: Test samples, with a membrane sandwiched between two test samples • Designed for coin‑cell simulation tests • Tighten the glassy carbon electrodes on both sides to compress positive and negative electrodes for electrical conduction to achieve battery‑test performance • Optical windows are fitted on both sides of the cell for real‑time observation of electrochemical reaction processes • Available sample sizes for this cell: 10 / 12 / 16 mm

Model: B001‑4 This version adds a reference electrode jack based on B001‑3, intended for three‑electrode electrochemical tests.
