PTFE-Bonded Acetylene Black Electrode Sheet for Primary Batteries, 300 μm

This preformed carbon electrode sheet requires controlled drying prior to cell assembly to remove residual moisture. The sheet must be handled in a clean, dry environment to prevent mechanical damage and contamination that could compromise electrode performance.

• Drying Requirement: Dry the electrode sheet at 90-100°C for 12-24 hours before cell assembly to ensure removal of adsorbed moisture.
• Handling Environment: Use a clean, dry handling environment after drying to avoid recontamination and moisture uptake.
• Mechanical Integrity: Avoid bending, scratching, or deforming the sheet during cutting, punching, transfer, and stacking to prevent structural defects.
• Contamination Control: Prevent contact with oils, dust, or other particulates that could introduce impurities into the battery assembly.

This procedure outlines the drying and handling steps required to prepare the carbon electrode sheet for primary battery cell assembly. Proper execution ensures electrode integrity and consistent electrochemical performance.

Required Equipment: Drying oven, Electrode punch or cutter

1. Dry the electrode sheet
   Dry the electrode sheet at 90-100°C for 12-24 hours to remove adsorbed moisture.
2. Transfer to clean environment
   Transfer the dried sheet to a clean, dry handling environment to prevent recontamination.
3. Cut to dimensions
   Cut or punch the sheet to the required dimensions without bending or scratching the surface.
4. Stack electrodes
   Stack the prepared electrodes carefully to avoid contamination and mechanical damage.

This 300 µm acetylene black-based, PTFE-bonded carbon electrode sheet provides a preformed roll format for primary battery research, with up to 95% carbon content and customizable width, but requires strict drying (12-24 h at 90-100°C) and careful handling due to low tensile strength.

Positive

• Preformed roll eliminates powder handling: Supplied as a flexible roll-form sheet rather than loose acetylene black powder, enabling consistent electrode fabrication and reducing airborne contamination in dry-room or glovebox workflows.
• High carbon content for conductivity: Acetylene black content up to 95% ensures excellent electronic conductivity, critical for primary-battery cathode performance in Li-SOCl2 and similar chemistries.
• Customizable width with tight tolerance: Available width from 50-300 mm with ±0.3 mm control allows direct integration into lab-scale cell hardware without additional slitting or trimming steps.

Trade-offs

• Mandatory extended drying step: The electrode sheet requires drying at 90-100°C for 12-24 hours before cell assembly, adding preparation time and necessitating a temperature-controlled oven with appropriate moisture control.
• Low mechanical strength limits handling: With a tensile strength >5 N, the PTFE-bonded sheet is mechanically delicate; bending, scratching, or contamination during cutting, punching, and transfer must be strictly avoided to maintain electrode integrity.
