Product Overview
FC-F Series Lithium Foil–Organic Cathode Material Cell Fixture uses an end-plate compression design to enclose lithium foil, a separator, electrolyte, and a cathode electrode in a sealed chamber. The FC1F has an effective reaction area of 1 cm² and accommodates 15.4 mm diameter lithium foil and cathode electrodes. The graphite flow-field plate on the cathode side provides electrical conduction, current collection, and electrolyte contact; the lithium foil on the anode side supplies Li⁺ and electrons. The cathode is typically carbon cloth or a composite electrode coated or filled with organic active material.

Working Principle
Discharge
The lithium foil on the anode side is oxidized: Li → Li⁺ + e⁻. Li⁺ migrates through the electrolyte and separator to the cathode. Electrons reach the graphite current collector through the external circuit, driving reduction of the organic active material and its reaction with Li⁺:
Organic + xLi⁺ + xe⁻ ⇌ LixOrganic
The graphite plate is normally a conductive current-collection component rather than the primary reactant. If the cathode consists only of bare graphite without an organic active layer, it should not be described as a reaction between lithium and an organic material.
Charge
An external power source drives the reverse process. Li⁺ leaves the organic cathode and returns to the lithium foil side, where Li⁺ + e⁻ → Li occurs at the foil surface.
Recommended Assembly Procedure
Recommended: position the lithium foil side first; close the cathode side last
Prepare and inspect
Make sure all parts are clean and dry. Prepare the lithium foil, electrodes, separator, and electrolyte in a glove box or another low-moisture, low-oxygen environment. Inspect the O-rings, insulating tubes, and current collector for damage or burrs.
Install the anode end plate and current collector
Lay the anode end plate flat, then install the connectors, insulating tubes, and anode current collector. If using the gold-plated collector, orient the plated face toward the lithium foil and avoid scratching it.
Place the lithium foil
Center the 15.4 mm diameter lithium foil on the anode current collector. Check that it is flat and free of wrinkles; if required by the assembly procedure, use a positioning ring or a small amount of electrolyte to wet the contact surface.
Add the separator and electrolyte
Place the separator so it fully covers the reaction area without extending into the sealing groove. Add electrolyte according to the test protocol, remove visible bubbles, and keep liquid out of the bolt holes.
Install the cathode electrode
Center the 15.4 mm diameter carbon-cloth or organic-composite cathode with its active face toward the separator. Make sure the electrode contacts the graphite flow-field plate.
Close the graphite flow-field plate and cathode end plate
Install the O-rings, spacers, graphite flow-field plate, and cathode end plate in order. Tighten the nuts diagonally and in stages for even compression; avoid damaging the separator or shifting the electrode.
Check sealing and electrical connections
Inspect the outer seal and verify there is no direct short circuit between the lithium foil and cathode current collector before connecting the electrochemical workstation or external load. Start the first test with low-current conditioning cycles if appropriate for the protocol.

Frequently Asked Questions
Is the graphite plate the active electrode?
The graphite plate mainly collects current and conducts electricity. The carbon cloth or organic active layer in contact with it is the part intended to participate in the reaction.
Why is the lithium foil side called the anode?
During discharge, lithium is oxidized at this electrode, making it the anode. It is also the negative electrode of the cell during discharge.
What does the gold-plated current collector do?
The gold-plated surface is intended to improve corrosion resistance and electrical contact stability for tests with demanding interface requirements.
Does assembly have to take place inside a glove box?
Lithium foil and many organic electrolytes are sensitive to moisture and oxygen. Assembly in a glove box or under rigorously dried inert-atmosphere conditions is recommended.
