Fueiceel® Manganese Dioxide Cathodes
A manganese dioxide cathode sheet series designed for aqueous zinc–manganese batteries, zinc-based batteries, and related electrochemical research. Stainless steel mesh is used as the conductive current collector. Standard double-sided and single-sided coating versions are available, with active-material loadings of 12, 24, and 48 mg/cm². Available formats include square electrodes, compact electrodes with exposed current-collection tabs, 90 × 76.5 mm sheets, and electrodes for coin-cell experiments.
Product Overview
Uses stainless steel mesh as the conductive and mechanical support framework, covering standard double-sided, single-sided, square-sheet, exposed-tab, and coin-cell formats.
Manganese dioxide cathodes are prefabricated cathode sheets designed foraqueous zinc–manganese batteries and related electrochemical systems. The electrode uses stainless steel mesh as the current collector, with a manganese dioxide active-material layer formed on the metal-mesh framework for convenient conductive connection to laboratory fixtures, leads, or battery structures.
Standard manganese dioxide cathodes use adouble-sided active-material structure, meaning that active-material layers are present on both sides of the stainless steel mesh current collector. Some specifications are explicitly identified asSingle-Sided. These products have active material on only one side, while the other side remains the stainless steel mesh current-collector surface. This configuration is suitable for experiments with specific electrode orientation or assembly requirements.
Standard active-material loadings include 12, 24, and 48 mg/cm². Electrode dimensions include 10 × 10 mm, 20 × 20 mm, 25 × 25 mm, 90 × 76.5 mm, and Φ12 mm. Some square-sheet formats use a “main body size + 10 mm current-collection area” notation; the additional +10 mm is the exposed stainless steel mesh current-collection region.

Current Collector
Active-Material Layer
Standard specifications use a double-sided coating structure. The stainless steel mesh is located within the electrode, with manganese dioxide active-material layers on both sides, making it suitable for general aqueous zinc–manganese battery and electrochemical-material experiments.
Single-Sided MnO₂ Cathode
Single-SidedActive-Material Layer
Current Collector
Exposed Side
Single-sided models have a manganese dioxide active-material layer on only one side, while the opposite side is the stainless steel mesh current collector. This configuration is suitable for experiments requiring a defined electrode orientation, contact method, or one-directional reaction interface.
Stainless Steel Mesh Current Collection
The stainless steel mesh provides both electrical connection and mechanical support for the electrode layer. Some models include an additional exposed current-collection region.
The metal mesh extends through the electrode body, providing mechanical support for the manganese dioxide electrode layer while establishing an electron-transport pathway.
For specifications marked 10 × (10 + 10) mm, 20 × (20 + 10) mm, and 25 × (25 + 10) mm, the additional +10 mm region is the exposed stainless steel mesh current-collection area.
The reverse side of a single-sided electrode has no active material, leaving the stainless steel mesh current collector exposed and making it easier to define the reaction side and current-collection direction.
Specifications & Pricing
The table below summarizes the 20 currently listed standard SKUs. Models marked “Single-Sided” have active material on only one side; all other standard models are shown as double-sided structures.

Quick Selection
Recommended selection sequence: Battery Structure → Single-/Double-Sided → Electrode Size → Active-Material Loading → Current-Collection Method.
Choose Single-Sided or Double-Sided
For general experiments, a double-sided structure can be considered first. If the reaction interface has a defined orientation, select a single-sided model.
Confirm Active-Material Loading
Current specifications cover 12, 24, and 48 mg/cm². Select the loading according to the experimental design.
Confirm Electrode Size
For small-scale experiments, choose 10, 20, or 25 mm square sheets. For larger-sheet experiments, choose 90 × 76.5 mm.
Determine Whether an Exposed Current-Collection Area Is Needed
If convenient clamping or wiring is required, choose a specification with an additional +10 mm stainless steel mesh current-collection area.
