Battery Cartridge – Three-Electrode Setup
Buy Redox.me products from NANOSSR at the best value.
This is default cartridge included in Three Electrode Battery Test Cell and other redox.me battery test cells. It is ideal choice when researcher wants to perform reproducible electrochemical measurements of battery and supercapacitor materials under controlled compression in a three-electrode setup. The battery cartridges are exchangeable between cell bases, therefore it is convenient to have multiple cartridges and use one while the other is in cleaning etc.
The Battery Cartridge – Three Electrode Setup consists of upper and lower electrode plungers, separator lock ring and reference electrode punch. The (default) electrode plungers are designed for planar electrodes with diameter of 18 mm and total sandwich thickness up to 2.5 mm. The diameter of separator shall be at least 2 mm larger than electrode diameter (max. 22 mm). The lock ring secures the separator in the electrode cartridge allowing easy and safe electrodes insertion, while ensuring accurate alignment. The upper and lower electrode plungers are available in various materials: 316L/317L Stainless Steel (default), copper, aluminum, nickel, gold plated nickel, etc. The punch-type reference electrode is installed from the side of the electrode cartridge. Thanks to sharp edged hole at the end of the pin the reference electrode (Li/Na/K etc.) can be easily punched from the metal foil and directly loaded into cell. The magnetic mount facilitates rapid assembly of the cartridge in the cell base For 2-electrode measurements the reference electrode feedthrough hole can be closed with the reference electrode punch.
The battery cartridge elements are constructed with materials that are inert to the sample (Stainless steel 316L/317L and PEEK). It well fits aqueous (FKM and EPDM O-Rings) and organic solvent (FFKM O-Rings) electrolyte requirements. Good electrical contact is ensured by gold plated pins. The battery cartridge can be effortlessly installed in the Three Electrode Battery Test Cell even when operating in the glove box, reducing possible human error to minimum.
Application Note:
This cell can be used for all common battery measurements, such as galvanostatic cycling, cyclic voltammetry or electrochemical impedance spectroscopy. Both liquid and solid-state electrolytes can be studied. Additionally, properties and performance of supercapacitor materials can be investigated. Various materials can be examined, including typical Li-ion electrodes (graphite, NMC, LTO, etc.) and other chemistries – sodium, magnesium, potassium etc. It can also be applied to measure the ionic conductivity of separators and electrolytes.
