Fueiceel® Nickel Hydroxide Cathodes
A nickel hydroxide cathode sheet series designed for zinc–nickel batteries, nickel-based aqueous batteries, and related electrochemical research. Three standard nominal-capacity options are available: 2.5 Ah, 3.0 Ah, and 3.8 Ah, corresponding to overall dimensions of 118 × 76.5 mm, 121 × 94 mm, and 141 × 94 mm. The electrodes use a sheet format with an exposed conductive tab for convenient laboratory assembly, electrical connection, and capacity-based cell selection.
Product Overview
Available in three standard capacity levels with a sheet-type cathode body and exposed conductive tab, suitable for zinc–nickel battery and nickel-based aqueous battery research.
Nickel hydroxide cathodes are prefabricated electrode sheets usingNi(OH)₂ as the primary cathode active system, and can be used for zinc–nickel batteries, nickel-based aqueous batteries, and related electrode-material and cell-structure research.
Current standard products are divided by nominal capacity into2.5 Ah, 3.0 Ah, and 3.8 Ahspecifications. As capacity increases, the overall electrode dimensions also increase. Select the appropriate version according to the target cell capacity, battery housing, and available assembly space.
The electrode uses a sheet-type body with an exposed tab for convenient electrical connection and laboratory assembly. The 2.5 Ah version measures 118 × 76.5 mm overall, the 3.0 Ah version measures 121 × 94 mm, and the 3.8 Ah version measures 141 × 94 mm.

Three Standard Capacity Options
The three products are distinguished by nominal capacity and overall dimensions, allowing quick matching to the target experimental cell capacity and installation space.
2.5 Ah Nickel Hydroxide Cathode
The most compact of the three standard products, suitable for experimental cell structures with tighter electrode-width and assembly-space requirements.
3.0 Ah Nickel Hydroxide Cathode
The intermediate-capacity option, with electrode width increased to 94 mm, suitable for research requiring a nominal capacity of 3.0 Ah.
3.8 Ah Nickel Hydroxide Cathode
The largest-capacity option in the current standard series. It retains the 94 mm width of the 3.0 Ah model while increasing the overall length to 141 mm.
Electrode Format & Capacity Levels
The CSS-based proportional illustration below shows the dimensional relationship among the three capacity options. No supplied product reference image is used.
Supplied as complete electrode sheets for convenient direct use in laboratory cell assembly and material research.
A conductive connection region is retained at the top of the electrode for convenient clamping, electrical connection, and assembly.
2.5, 3.0, and 3.8 Ah cover three standard capacity levels for convenient system matching.
Different capacities use different overall dimensions. Check both capacity and available assembly space when selecting a product.
Specifications & Pricing
The current product group contains 3 standard SKUs. The prices shown are the selling prices from the website product list.
| Nominal Capacity | Overall Dimensions | Width | Overall Length | Reference Price |
|---|---|---|---|---|
| 2.5 Ah | 118 × 76.5 mm | 76.5 mm | 118 mm | ¥70 |
| 3.0 Ah | 121 × 94 mm | 94 mm | 121 mm | ¥80 |
| 3.8 Ah | 141 × 94 mm | 94 mm | 141 mm | ¥86 |
Quick Selection
Select the electrode by considering both target capacity and the installation space inside the battery rather than capacity alone.
Compact Experimental Structures
Overall dimensions: 118 × 76.5 mm. This is the narrowest of the three options and is suited to relatively compact assemblies targeting a 2.5 Ah nominal capacity.
Mid-Capacity Experiments
Overall dimensions: 121 × 94 mm. If the target capacity falls between the three standard options, the 3.0 Ah version can be selected as the intermediate choice.
Higher-Capacity Experiments
Overall dimensions: 141 × 94 mm. This is the longest option in the current series and is suited to experiments targeting 3.8 Ah where sufficient internal space is available.
Applications
Suitable for research involving nickel hydroxide cathodes, zinc–nickel batteries, and nickel-based aqueous battery systems.
Used as the cathode in zinc–nickel batteries for cell assembly and experimental-system research.
For material and structural research on aqueous batteries using nickel-based cathodes.
For research on nickel hydroxide cathode materials, electrode structures, and assembly methods.
Enables experiments comparing the 2.5, 3.0, and 3.8 Ah capacity levels.
For studying dimensional compatibility among the cathode, anode, separator, and battery housing.
For assembly research using different cathode areas and overall dimensions.
The prefabricated sheet format facilitates rapid laboratory assembly of aqueous batteries.
Suitable for research and teaching experiments involving nickel-based cathodes and aqueous batteries.
Selection & Handling Guide
Before selection, confirm the capacity, overall dimensions, conductive-tab position, and available assembly space in the target battery.
Determine the target capacity—2.5, 3.0, or 3.8 Ah—according to the experimental plan.
After selecting the capacity, verify that the corresponding overall electrode length and width fit the target battery structure.
Confirm the orientation of the conductive tab before assembly to avoid interference with the housing, fixture, or other electrodes.
Avoid excessive bending, compression, or damage to the electrode body and tab connection area during handling and assembly.
