How does the 99.9% pure aluminum coating on the LIR2430 coin cell case improve electrochemical testing accuracy?
The 99.9% pure aluminum coating, approximately 1 µm thick, provides a consistent and low-contamination contact surface on the positive case, minimizing unwanted side reactions and ensuring reliable electrochemical data.
What are the exact outer dimensions of the LIR2430 aluminum-coated coin cell case to ensure proper fit in standard battery testing equipment?
The overall finished size is 24 mm diameter x 3.0 mm height, with an upper cover outer diameter of 23.75 ±0.05 mm and a lower case outer diameter of 24.45 mm, ensuring compatibility with 2430-class fixtures.
What gasket material is used in the LIR2430 aluminum-coated coin cell case and how does it contribute to cell sealing?
The gasket is made of polypropylene (PP), which provides electrical insulation and sealing between the upper cover and lower case to prevent short circuits and electrolyte leakage.
The LIR2430 aluminum-coated coin cell case combines a 304 stainless steel base with a 99.9% pure aluminum coating on the positive case, providing a defined electrochemical interface for battery research. The thin coating and PP gasket impose handling and compatibility constraints that must be considered in cell assembly.
Positive
- 99.9% pure aluminum coating: The 1 µm thick aluminum coating on the positive case provides a well-defined, high-purity interface for electrochemical studies, minimizing contamination from the stainless steel substrate.
- 304 stainless steel construction: The base case material offers robust mechanical strength and corrosion resistance, ensuring structural integrity during crimping and handling.
Trade-offs
- Thin coating vulnerability: The approximately 1 µm aluminum coating is susceptible to mechanical abrasion, pinhole defects, or galvanic corrosion if the substrate is exposed, requiring careful handling and assembly.
- Polypropylene gasket constraints: The PP gasket limits operating temperature range (typically -20 to 120°C) and may swell or degrade in certain organic electrolytes, restricting solvent compatibility.
