Custom Electrode Sheet Coating for Battery R&D
Atomfair provides research-scale custom battery electrode sheet coating for laboratories and R&D teams. We coat custom cathode and anode sheets around the requirements of the actual experiment: battery chemistry, active material, formulation, current collector, areal loading, coating geometry, cell format, and validation plan.
The service covers lithium-ion, sodium-ion, lithium-sulfur, zinc-based, and emerging battery systems. Custom electrode rolls, cut sheets, punched samples, and pouch-cell electrode sheets can be supplied, with optional cell assembly and electrochemical testing defined for the project.
What Can Be Customized
| Development Area | Parameters Defined for the Project |
|---|---|
| Battery system and electrode role | Lithium-ion, sodium-ion, lithium-sulfur, zinc-based, and emerging systems; cathode or anode electrode design. |
| Electrode formulation | Active material, binder, conductive additive, formulation ratio, and specified electrode composition. |
| Coating and geometry | Wet or dry process, continuous or intermittent coating, single- or double-sided coating, loading, coated area, dimensions, and uncoated margin. |
| Current collector | Aluminum or copper foil, selected thickness, carbon-coated collector, safety-coated collector, and specified surface or cut geometry. |
| Delivery and validation | Rolls, cut sheets, punched discs, pouch-cell sheets, optional coin-cell or pouch-cell assembly, and agreed electrochemical test plan. |
Custom Electrode Sheet Coating Options
Battery Systems and Electrode Roles
Projects may begin with a supplied active material, an existing laboratory formulation, or defined cell-design requirements. Supported coating work includes lithium-ion cathodes and anodes, sodium-ion cathodes and hard-carbon anodes, sulfur composite cathodes, zinc-based electrodes, and feasibility review for emerging chemistries. The coating scope is confirmed from the intended electrochemical system and research objective.
Wet and Dry Electrode Coating
Wet electrode coating and dry electrode coating can be evaluated according to the material system and experimental requirements. Projects can specify continuous coating for long coated areas or intermittent coating for defined active zones, uncoated tab areas, and pouch-cell electrode geometry. Single-sided and double-sided coating configurations are reviewed according to the required electrode architecture.
Loading, Formulation and Coated Electrode Specification
A custom coating specification may define active material ratio, binder and conductive additive system, areal loading, electrode thickness, density or porosity requirement, coating width, coated area, and sheet dimensions. For full-cell projects, the coated electrode specification can be developed with the intended matching electrode, practical areal capacity, and cell format in mind.
Current Collector and Interface Options
Standard aluminum and copper foil collectors are available with selected thickness and dimensions. Carbon-coated current collectors can be considered where coating adhesion, contact resistance, or interface behavior is a project variable. Safety-coated current collectors are available for projects involving specific protection or thermal-response concepts. Collector type, surface treatment, coating side, and uncoated margins are specified before fabrication.
Roll, Sheet and Punched Electrode Delivery
Custom electrodes can be delivered as rolls for in-house cutting and repeated experiments, cut sheets for direct laboratory use, punched discs for a defined coin-cell format, or pouch-cell electrode sheets with specified dimensions and tab zones. The delivery format should be set at project start because it affects coating geometry, handling, and the downstream assembly route.
Optional Cell Assembly and Electrochemical Testing
| Optional Project Stage | Scope Defined Before Work Starts |
|---|---|
| Coin-cell assembly | Half-cell or full-cell configuration, counter or matching electrode, separator, electrolyte, and testing objective. |
| Pouch-cell assembly | Electrode dimensions, stack design, N/P relationship, electrolyte amount, formation procedure, and intended pouch-cell format. |
| Formation and cycling | Voltage window, formation cycles, C-rate, temperature, cut-off criteria, sample quantity, and data format. |
| Electrochemical characterization | Agreed studies such as cycling, rate performance, DCIR, EIS, or CV, with project-specific test conditions and reporting scope. |
Test plans, sample quantities, and report contents are agreed case by case. Research data are reported under the defined conditions and do not constitute production-cell qualification or certification.
Start with a Project Specification
Not every parameter must be finalized before you contact us. The information below lets us determine whether the project can proceed directly to fabrication or first needs an electrode or cell-design feasibility review.
- Battery system and electrode role: for example, sodium-ion hard-carbon anode, lithium-ion LFP cathode, or sulfur composite cathode.
- Active material and formulation: supplied material, required formulation, or material route to be discussed.
- Coated electrode specification: loading, thickness or density, coating side, coating area, dimensions, and uncoated margin where applicable.
- Current collector and process: foil type, thickness, carbon or safety coating, wet or dry process, and continuous or intermittent coating where specified.
- Quantity and delivery: total area or length, number of samples, roll, sheet, disc, or pouch-cell electrode format.
- Downstream validation: intended cell format, matching electrode or counter electrode, and any required formation, cycling, or characterization data.
