TSC Battery

Product Description
A closed measuring cell intended for assembling half or full battery or supercap cells with e.g. active materials and separators. It is also suitable for investigating solid or gel-like samples in contact with metal electrodes in a plate/plate geometry.
Both two and three electrode measurements can be performed by inserting a microreference electrode or a custom lithium reference from the side.
This cell is airtight and thus shielded against atmosphere and can be used with moisture-sensitive samples.
The TSC Battery is available in different variants in regards to the included current collectors and and as a less complex and cheaper 2-electrode-only variant. Please see below for further details about the available cell variants.

Detailed Description

The measuring cell TSC Battery is based on a nickel-plated thermo block with integrated Pt100 temperature sensor. The cell is available in the two designs "standard" and "extended":

The "standard" version allows the investigation of planar samples of variable shape like active material for modern energy storage systems deposited on substrates, electrolyte soaked separators or solid ion conducting materials.

The "extended" version comes with two additional current collectors with punching edge, which enable the use of elemental lithium as electrode material.

For both cell designs, the loaded cell is sealed from the outside by a PEEK housing with several o-rings. Thus, sensitive materials are protected from the influence of oxygen or humidity. The housing of the three-electrode variant provides two lateral inlets for reference electrodes. These are located exactly in the middle between both electrodes.

The lateral inlets are fabricated in a way that elemental lithium as pseudo reference electrode as well as capillary-based micro-reference electrodes can be inserted.

Furthermore, additional electrolyte can be added into the three-electrode cell through one lateral inlet using rhd's capillary filling system.

The contact pressure applied to the current collectors and in turn on the samples can be adjusted with good precision by means of a spring.

The top side of the cell is closed with a screw cap made of PEEK which is equipped with a contact spring.

Technical Details
