The ECD-2-DL is a research grade instrument dedicated to the mea-surement of charge-induced strain (expansion and shrinkage) of elec-trodes down to the sub-micrometer range. The dilatometer has beenparticularly developed for the investigation of Li-ion battery and otherinsertion-type electrodes. It may be used in organic as well as aqueouselectrolyte solutions. The heart of the ECD-2-DL is an electrochemicalcell, hermetically tight against ambient atmosphere. The two electrodes

inside are separated by a stiff glass frit that is fixed in position. Theupper (working) electrode is sealed by means of a thin metal memb-rane, through which any charge-induced height change is transmittedtowards the sensor/load unit that is attached from top.

A high-resolution LVDT displacement transducer detects dimensionalchanges ranging from 50 nanometers up to 500 micrometers, duringone and the same experiment that may last between a few seconds tomany days. The samples electrode potential may be controlled againsta reference electrode that is positioned in close proximity to the workingelectrode.

The ECD-2-DL comes with an integrated data logger recording the dis-placement signal together with the electrode potential, the cell currentand the temperature. The displacement and temperature signal are alsoavailable at the analog output connector, thus enabling seamless inte-gration into many of todays electrochemical workstations and batterytesters.

Enabling Electrochemical Dilato-metry in the Nanometer ScaleThe new ECD-nano-DL electrochemical dilatometer has a resoluti-on in the true nanometer range. This new development is fully com-patible with the ECD-2-DL, except for the sensor/load unit. With thenew capacitive parallel-plate sensor system, the ECD-nano-DL pro-vides a much better resolution below 5 nanometers (against 50 nmfor the ECD-2-DL). The high resolution of the ECD-nano-DL opensnew fields of application to electrochemical dilatometry. Quasi2 -dimensional electrode processes like the SEI formation in lithium-ionbatteries, or the electrochemically driven growth of passivation layers onmetal surfaces might become the subject of future dilatometric studies.

Just like the ECD-2-DL, the ECD-nano-DL provides an analog signal out-put that allows for seamless integration into the software applicationsof many of todays electrochemical workstations and battery testers.

Features Highly precise concentric alignment of the two electrodes for 18 mm diameter electrode size easy handling

ECC-RefLoadThe ECC-RefLoad is an indispensable tool to conveniently load lithiummetal into the REF bore of the ECC-Ref.

ECC-CellLoadelectrode allignment and assembly tool

When building full cells with thin Celgard type separators, the concen-tric alignment of the two electrodes with the oversized separator inbetween is key for electrochemical performance and life time. TheECC-CellLoad is the tool to get that done easily.

Basically, the tool is a small tube (cannula) with a knock-out pin inside.A tiny piece of lithium metal is first picked up by pressing the cannulaonto a piece of lithium foil (>0.2 mm thick). The cannula is then insertedinto the bore of the REF sleeve, and the lithium inside the cannula isextruded into the REF bore by actuating the knock-out pin.

The picture shows, for de-monstration purposes, howthe lithium metal can be ex-truded through the REF boreforming a thin wire. In practi-ce, push the lithium just to theinner surface of the REF Slee-ve, no more, no less.

El-CutHigh Precision Cutting Pliers

Accuracy and reproducibility of electrochemical tests depend not onlyon the choice of materials, but also on simple geometric / mechanicalparameters. One sometimes neglected factor is the proper cutting of theelectrodes. Torn and chipped electrode edges, even when not seen with

the naked eye, inevitably cause current inhomogeneity and are thuslikely to affect experimental results. Especially cycle life and impedanceresults are prone to such artefacts.

Electrodes cut by conventional punching (stamping) with only onepunch force show chipped edges and are not flat. In contrast,electrodes cut with the EL-CUT are produced with three active forcesand in tools with a few microns cutting clearance. This high precisioncutting process results in electrodes with clean cutting surfaces with notorn or chipped edges and being almost perfectly flat.

ECC-StopRailCross hairs to reduce cutting scrap

Dont waste your precious electrode material! When attached to thecutting pliers, the crosshairs of the ECC-StopRail let you precisely targetthe electrode area.

The ECC StopRail is an optional tool to be attached to the EL-Cut cuttingpliers. The ECC-StopRail helps to conveniently target the cutting areaand thus to make effective use of the electrode sheet, and to speed upthe cutting process.

The ECC-STANDdocking station thus allows for a permanent connection between agiven tester channel and the corresponding cell position inside thestand, thereby helping to prevent the common wiring trouble and riskof failure when operating multiple cells in parallel.

The ECC-STAND can be wall-mounted, placed inside a temperature

chamber, or simply sit on the bench top.
