5 Air-cathode materials Current collector: 304 Stainless Steel Meshed Disc (80 mesh woven from mm dia. Wire, Alfa Aesar) as Electrode Substrate for CR2032 – EQ-SSMD-304 (MTI.Corp.) Active material: Graphite Super C65 (CAS: – TIMCAL) Binder: PVDF ADX 161 (CAS: – Arkema) Solvent for slurry preparation: N-methyl-2-pyrrolidone (CAS: – Sigma Aldrich, anhydrous, 99.5% ) Diameter for Swagelok cell: 10 mm Diameter for coin cell: 14 mm Composition ref.
6 Swagelok cell Why is it the good choice. -Everybody is using it, easier to compare to previous results -Cheap and Versatile cell: Possibility to change each component one by one Possibility to tune (melting by spot resistance, 2 or 3 electrodes, line of several cells…) Contacts melt by spot resitance Gas in Gas out Vale for charge /discharge Battery
