Graphite Electrode Selection Logic
This double-sided graphite anode sheet is positioned as a baseline lithium-ion anode for comparing cathode matching, electrolyte behavior, formation conditions, and process variables. The coating loading, active material ratio, collector areal density, and coating process provide the calculation basis for punched-electrode mass and cell balancing.
For experiments that require a different graphite loading, coating area, current collector, or delivery format, review Atomfair Custom Battery Electrode Coating Service.
| Research Use Case | What This Product Helps Evaluate |
|---|---|
| Baseline graphite anode testing | Builds a repeatable graphite-side reference for lithium-ion half-cell or full-cell experiments. |
| Electrolyte and additive screening | Supports comparison of electrolyte systems under a defined graphite loading and coating process. |

Handling, Storage and Pre-Use Treatment
- Use a dry handling environment before cell assembly to reduce moisture exposure on the coated electrode surface.
- Store opened sheets in a dry environment or inert atmosphere to reduce moisture exposure before use.
- Avoid touching, bending, scratching, or contaminating the coated surface during punching, transfer, and stacking.
- For coin-cell or pouch-cell testing, calculate active material mass from coating loading, active material ratio, and punched electrode area.

Handling constraints apply before and after electrode punching. Moisture exposure and mechanical damage to the coated surface must be minimized.
- Moisture sensitivity: Use a dry handling environment before cell assembly to reduce moisture exposure on the coated electrode surface.
- Storage atmosphere: Store opened sheets in a dry environment or inert atmosphere to reduce moisture exposure before use.
- Surface integrity: Avoid touching, bending, scratching, or contaminating the coated surface during punching, transfer, and stacking.
- Active material mass calculation: Calculate active material mass from coating loading, active material ratio, and punched electrode area before cell assembly.
Prepare the graphite anode sheet in a dry handling environment before cell assembly. Protect the coated surface from mechanical damage and calculate active material mass from punched electrode area.
- Transfer to dry handling environment
Transfer the electrode sheet to a dry handling environment before cell assembly. - Inspect coated surfaces
Inspect both coated surfaces for visible scratches, bends, or contamination before punching. - Punch electrodes
Punch the required electrode shape from the coated area while keeping the coated surface free from contact. - Calculate active material mass
Calculate active material mass from coating loading, active material ratio, and punched electrode area before cell assembly. - Store punched electrodes
Store opened sheets and punched electrodes in a dry environment or inert atmosphere until use.
How do I calculate the active graphite mass for a punched electrode from this double-sided anode sheet?
To calculate active graphite mass, multiply the coating loading (14.4 mg/cm²) by the punched electrode area and the active material ratio (96.50%). For example, a 15 mm diameter electrode (area 1.767 cm²) yields approximately 14.4 × 1.767 × 0.965 = 24.5 mg of active graphite. The product description explicitly instructs to calculate active material mass from coating loading, active material ratio, and punched electrode area.
What cathode electrode sheets are recommended for full-cell balancing with this graphite anode?
The product listing recommends pairing this double-sided graphite anode with lithium-ion cathode electrode sheets from Atomfair’s dedicated category to enable full-cell balancing and N/P ratio design. The source states that for full-cell work, the anode design should be used to match cathode loading and practical electrode area, and it links directly to the cathode electrode sheets category for selection.
What are the required handling and storage conditions for this double-sided graphite anode electrode before cell assembly?
The electrode must be handled in a dry environment to minimize moisture exposure, and opened sheets should be stored in a dry environment or inert atmosphere. The coated surface must not be touched, bent, scratched, or contaminated during punching, transfer, or stacking. These conditions are specified in the product's handling, storage, and pre-use treatment section.
This double-sided graphite anode electrode sheet with 14.4 mg/cm2 coating loading and 96.50% active material ratio provides a well-defined baseline for lithium-ion battery research, suitable for electrolyte screening and cathode matching. Its carbon-coated copper foil current collector and wet-process coating ensure consistent electrode properties, but require strict dry handling and careful surface protection during use.
Positive
- High active material ratio: 96.50% active material ratio minimizes binder and conductive additive content, maximizing electrochemical capacity per unit mass in half-cell or full-cell testing.
- Defined coating parameters for reproducibility: Specified coating loading, compaction density, and current collector areal density enable precise active mass calculation and consistent cell balancing across experiments.
Trade-offs
- Moisture sensitivity requiring dry handling: The coated electrode surface must be stored and handled in a dry environment or inert atmosphere before cell assembly to prevent moisture absorption that could degrade electrochemical performance.
- Fragile coated surface requiring careful handling: The double-sided coating is susceptible to damage from touching, bending, scratching, or contamination during punching, transfer, and stacking, necessitating meticulous handling protocols.
