  S2 and BiPot

  Nexus includes a Second Sense lead (S2) and an optional BiPotentiostat (BiPot) module.

  S2 – Additional voltage (potential) measurement point

  BiPot – Independent second working electrode for simultaneous current measurement

  These two features are independent and serve distinct purposes:

  • S2 (Second Sense Lead)
    S2 acts as an additional voltage-sensing input, with the same specifications as the main reference electrode. It measures the potential at a specific point in the cell and, because the current at that point is known, it can also be used to calculate impedance.
  • BiPot (BiPotentiostat Module)
    The BiPot module introduces a second working electrode (WE2), operating versus the same reference and counter electrodes as the main channel. In BiPotentiostat mode, both working electrodes (WE1 and WE2) are recorded simultaneously. WE2 operates in potentiostatic mode, meaning it can independently control its potential and measure its current.

  Sample Holder 25 mm x 25 mm (redox.me)

  The sample holder (known also as flat specimen holder) is used for holding flat, circular or square/rectangular samples. It enables contacting the sample from the front (e.g. ITO/FTO glass, Monolayer Graphene on SiC, or Boron-Doped Diamond thin film on various substrates) and from the back (e.g. metal specimen, Glassy Carbon plate, Boron-Doped Diamond plate). The default nominal aperture is 1cm², but other value can be provided on request. The large electrical contact with Tantalum (formerly Copper) foil surface (not being in contact with an electrolyte) ensures optimal current collection by minimizing electrical resistance and unifying current distribution. The rod with electrical connection has a diameter of 6 mm, which makes the sample holder compatible with our voltammetry cells and jacketed cells, as long as it fits in. We may also provide an adapter to install this sample holder in openings larger than 6 mm dia.

   

  The sample holder elements are constructed with materials that are inert to the electrochemical system (PEEK, Fluorocarbons). It well fits aqueous (FKM/EPDM O-Rings) and organic solvent (FFKM O-Rings) electrolyte requirements. The construction is well sealed which prevents the electrolyte to leak inside.

   

  Application note
  The sample holder is used largely for corrosion studies. It can be installed in a beaker type cell as well as in testing environments such as open water reservoirs, cans, tanks etc. It can also be used wherever it is necessary to make an electrode using a thin layer of an active material deposited on a flat substrate (conducting or insulating).

  Three Electrode Battery Test Cell – compression controlled (redox.me)

  This cell is designed as high-quality alternative to Swagelok-type constructions for reproducible electrochemical measurements of battery and supercapacitor materials.

  The cell consists of two main elements:

   

  (i) the cell base with micrometre screw and compression spring, which allows precise control of pressure applied to the electrode sandwich; and

  (ii) electrode cartridge where the anode, cathode and reference electrode are located.

   

  The (default) electrode cartridge and plungers are designed for planar electrodes with diameter of 18 mm and total sandwich thickness of 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 Stainless Steel (default), copper, aluminum, nickel etc. The pin-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. The force applied to the electrodes can reach up to 90N and is adjusted with the micrometer control knob. For 2-electrode measurements, the reference electrode feedthrough hole can be closed with the reference electrode punch.

  The cell elements are constructed with materials that are inert to the sample (Stainless steel 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 construction is gas-tight and can be effortlessly assembled 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 or gel-polymer 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. Owing to the micrometer control knob, the relationship between the initial pressure applied to the cell and the performance of solid-state electrolytes or metal plating process (anode-free systems) can be studied.

   

  The above graph shows relation of pressure applied to electrode stack and distance travelled from the point of contact. The point of contact can be determined by checking OCV (see manual video) or by calculation. To calculate the point of contact, subtract electrode stack thickness from 4 mm. For example, for the 0.9 mm stack, the point of contact (i.e. reading on micrometer screw) will be 4 mm – 0.9 mm = 3.1 mm. Therefore, you should set micrometer screw to 3.1 mm and measure distance/pressure relation from this point.

   

  Specification:
  recommended electrode diameter: 18 mm (other options: 12 mm, 15 mm, 16 mm)
  recommended minimum separator diameter: electrode diameter + 2 mm (max. 22 mm)
  maximum electrode sandwich thickness: 2.5 mm
  spring rate: 10.86 N/mm
  maximum spring load: 90 N
  operating temperature: -40°C – 80°C (default)
