Graphite Electrode Sheet (99.99% C)

High-purity graphite electrode sheet (99.99% carbon) is a chemically stable, electrically conductive electrode substrate used in battery testing and general electrochemistry. Graphite provides a robust electron-conducting path while maintaining good resistance to many electrolyte environments, making it suitable for routine lab fabrication of planar electrodes, current distribution plates, and conductive fixtures.

How it works

In electrochemical cells, the graphite sheet acts as an inert conductive electrode or current spreader. Its high electronic conductivity supports uniform current distribution across the active area, helping reduce local hot spots and improving repeatability in lab-scale testing.

Key specifications & options

• Purity: 99.99% carbon (graphite)
• Standard size (example): 100 × 50 × 2 mm
• Packing: 5 pieces per bag
• Other common sizes: Multiple thicknesses and footprints (e.g., 100 × 50 mm, 100 × 100 mm, 200 × 100 mm, 300 × 200 mm, 400 × 400 mm)
• Custom sizing: Available to suit customer requirements (cut-to-size / customised dimensions)
  
  

Compatibility & use cases

• Electrode plates for aqueous and non-aqueous electrochemistry
• Battery R&D setups (coin, pouch, and custom lab cells) as a conductive plate, counter electrode, or current distributor
• Prototyping fixtures where machining/cutting of graphite is preferred over metals (low contamination risk)
