Key Characteristics of high capacity nickel-based t metal hydride alloy powder for nickel metal hydride battery
-
Particle Size and Distribution: The size and uniformity of particles significantly influence flowability, packing density, and the final product’s mechanical and physical properties. Finer powders generally offer a larger surface area, which is beneficial for reactions and sintering but may also increase aggregation.
-
Composition: Metal powders can be elemental (pure metal) or alloyed, combining two or more metals to achieve desired properties such as enhanced strength, corrosion resistance, or electrical conductivity.
-
Shape: Particle shapes range from spherical to irregular or flake-like. Spherical powders provide better flowability and packing, while flake-shaped powders are suited for coatings and electronic applications due to their unique orientation and surface area.
-
Purity: Depending on the application, metal powders can be highly purified to remove impurities, critical for uses in electronics, aerospace, and medical devices where contamination could compromise performance.

Parameters of high capacity nickel-based t metal hydride alloy powder for nickel metal hydride battery
A high-capacity nickel-based metal hydride (NiMH) alloy powder used in nickel metal hydride batteries typically has the following key parameters:
1. Composition: The powder usually consists of Nickel (Ni), usually around 50-65% by weight, and other elements like Cobalt (Co), Manganese (Mn), Aluminum (Al), Lithium (Li), or sometimes Silicon (Si) to improve performance and stability.
2. Particle size distribution: The powder particles have a narrow size distribution, typically ranging from 40 to 100 microns, to ensure consistent electrode performance and efficient use of the active material.
3. Purity: High purity is essential, with impurities below a certain level to minimize side reactions and maintain the battery’s efficiency.
4. Porosity: The powder may contain a controlled amount of porosity, which helps to facilitate hydrogen storage and release during charge/discharge cycles, enhancing the overall energy density.
5. Crystal structure: The NiMH alloy particles usually exhibit a cubic or hexagonal crystal structure, such as LixNi(Mn,Co)O2 (NMC), LiNi0.8Co0.15Al0.05O2 (NCA), or LiNi0.8Mn0.1Co0.05O2 (NMC), which determines the electrochemical properties.
6. Specific surface area: A higher specific surface area allows for more active material contact with electrolyte, leading to improved power output and cycle life.
7. Density: The powder density should be high enough to achieve good packing efficiency in the final cell but not too high to affect handling and manufacturing processes.
8. Electrochemical performance: Key performance parameters include high gravimetric (energy density) and volumetric (power density), good rate capability (ability to deliver power quickly), and long cycle life.
9. Thermal stability: The alloy must have good thermal stability to prevent degradation during charging and discharging cycles.
10. Safety: The powder should be non-flammable and non-explosive to ensure safe operation.
These parameters are subject to optimization based on the specific requirements of the application, such as portable electronics, electric vehicles, or grid-scale energy storage systems.
