XIAMENMnO₂ Electrode for Zinc-Manganese Batteries
Product Overview
The manganese dioxide (MnO₂) electrode is a customizable cathode solution designed for zinc-manganese battery systems and electrochemical research applications. It is widely used in laboratory studies involving manganese-based electrochemistry, including primary batteries and aqueous energy storage systems.
The electrode is constructed using manganese dioxide as the active material and stainless steel mesh as the current collector, ensuring stable electrical conductivity and structural integrity. With a typical specific capacity of up to 200 mAh/g, the product provides reliable electrochemical performance for research and testing.
This product is offered as a custom electrode fabrication service, allowing flexible design in terms of size, loading, and structure to meet different experimental requirements.
Structure and Materials
The electrode adopts a standard composite electrode structure:
Active Material: Manganese dioxide (MnO₂)
Current Collector: Stainless steel mesh
Coating Layer: Uniformly distributed MnO₂ slurry
This structure ensures:
Stable electron transport
Good adhesion between active material and collector
Consistent electrochemical performance
