Core Product Overview
Product Name: Manganese Dioxide Electrode Sheet
Basic description: This is a pre fabricated thin film electrode with manganese dioxide (MnO2) as the main active material. It is a key semi-finished product for manufacturing primary batteries (non rechargeable) or core components of supercapacitors.
Main features and advantages
High purity and consistency:
Using high-purity electrolytic manganese dioxide (EMD) as raw material to ensure the stability and reliability of electrochemical reactions.
Industrial production ensures that each batch of manganese dioxide electrode sheets has highly consistent quality and performance, which is crucial for large-scale battery production.
Optimized formula and structure:
In addition to the active substance MnO2, the formula also includes conductive agents (such as acetylene black, graphite) and binders.
This optimized mixture ensures that the manganese dioxide electrode sheet has good electronic conductivity, structural strength, and adhesion to the current collector.
Excellent electrochemical performance:
High energy density: MnO2 is an excellent positive electrode material that can provide high specific capacity and voltage plateau.
Stable discharge characteristics: The electrode plate is designed to provide a smooth discharge voltage, which is crucial for devices that require a stable power supply.
Low self discharge rate: High quality materials and structures help reduce battery power loss during storage.
Ready to use and customizable:
As a semi-finished product, manganese dioxide electrode sheet can be directly used in battery assembly lines, simplifying the production process.
Sturdy base:
The electrode sheet is usually attached to a current collector (shown as a metal mesh in the product diagram, usually nickel plated steel mesh or expanded metal mesh), which provides a sturdy channel for electronic conduction and enhances the mechanical strength of the electrode.
Typical application areas
This type of manganese dioxide electrode sheet is mainly used to manufacture the following types of batteries and devices:
Alkaline zinc manganese dioxide battery: This is the positive core of the most common AA, AAA and other alkaline batteries in our daily lives.
Lithium manganese dioxide battery: a common disposable lithium primary battery, usually a button battery or cylindrical battery, widely used in devices such as watches, computer motherboards CMOS, remote controls, etc.
Zinc carbon battery: the positive electrode material of traditional dry batteries.
Magnesium manganese dioxide batteries: used in some special high-performance military or industrial fields.
Supercapacitors/Hybrid Capacitors: MnO2 is also commonly used as an electrode for supercapacitors in aqueous electrolytes, providing high power density and a certain energy density.
