5mm Thickness Iron Nickel Foam For Battery Electrode Materials

SPECIFICATIONS

The application of iron-nickel foam in batteries is primarily reflected in its potential as an electrode material, especially in nickel-metal hydride (NiMH) batteries and lithium-ion batteries. Below is a detailed explanation:

1. Application in Nickel-Metal Hydride Batteries

Nickel-metal hydride batteries consist of a nickel cathode, a hydrogen storage alloy anode, and an alkaline electrolyte. Iron-nickel foam offers the following advantages as a cathode material:

High Conductivity: The three-dimensional structure of iron-nickel foam provides excellent conductivity, enhancing the charge-discharge performance of the battery.

Large Specific Surface Area: Its porous structure increases the contact area between the electrode and the electrolyte, promoting electrochemical reactions and improving battery capacity and rate performance.

Mechanical Strength: Iron-nickel foam exhibits good mechanical properties, enabling it to withstand volume changes during charge-discharge cycles, thereby extending battery life.

2. Application in Lithium-Ion Batteries

In lithium-ion batteries, iron-nickel foam is primarily used as an anode material, offering the following characteristics:

High Specific Capacity: The theoretical specific capacities of iron and nickel are relatively high, contributing to improved energy density of the battery.

Structural Stability: The porous structure of iron-nickel foam alleviates stress during lithium-ion intercalation and deintercalation, reducing electrode material cracking and extending cycle life.

Conductivity: Its three-dimensional conductive network enhances electron transport efficiency, improving the rate performance of the battery.

3. Applications in Other Battery Systems

Iron-nickel foam can also be used in other battery systems, such as:

Sodium-Ion Batteries: As an anode material, its porous structure and high conductivity enhance the performance of sodium-ion batteries.

Supercapacitors: As an electrode material, its high specific surface area and conductivity help increase the energy density and power density of supercapacitors.
