In the world of battery casings, two primary materials reign supreme: aluminum and steel. However, if you seek unparalleled advantages in terms of longevity and safety, aluminum stands out as the prime choice. In this article, we’ll explore the remarkable features of aluminum battery casings and why they outshine traditional options.
Aluminum Battery Casings: Unmatched Versatility
When it comes to crafting battery casings, malleability is a vital factor. Aluminum boasts an exceptional degree of malleability, making it a top choice for shaping intricate designs and meeting specific requirements.
High-Temperature Corrosion Resistance
Aluminum battery casings excel in high-temperature environments. Their corrosion resistance under elevated temperatures ensures the longevity of your batteries, even in challenging conditions.
Excellent Thermal Conductivity
Efficient heat dissipation is crucial for battery performance and safety. Aluminum’s excellent thermal conductivity helps in dispersing heat, preventing overheating, and extending the life of your batteries.
Outstanding Electrical Conductance
In the world of batteries, electrical conductivity is non-negotiable. Aluminum’s remarkable electrical conductance ensures a seamless flow of power within the casing, contributing to enhanced battery performance.
Singular Stretch-Forming: A Game-Changer
One of the standout features of aluminum battery casings is the process of singular stretch-forming. This innovative method eliminates the need for bottom welding processes, a common source of concern with traditional materials. By avoiding welding, the potential degradation of weld seam quality due to metal element burn-off is completely averted.
Longevity Beyond Compare
Extended Operational Lifespan
Simulated aging tests have proven that aluminum battery casings can offer an operational lifespan exceeding two decades. This far surpasses the longevity of traditional metal casings, making them a reliable choice for long-term use.
Safety is paramount, and aluminum battery casings excel in this aspect. They exhibit flame retardance, releasing no smoke or toxins. Aluminum is inherently fire-resistant and boasts a fire-retardant rating of FV0. In high-temperature conflagrations, the smoke emission is rated at level 15 on a scale of 1 to 100. This means non-toxic fumes are released, classifying it under toxicity level ZA1, signifying a preliminary safety level 1.
Built-In Safety Mechanisms
In cases of excessive internal pressure within the battery core, aluminum battery casings feature an automatic pressure relief mechanism. This ingenious feature averts the occurrence of explosions, enhancing overall safety.
Exceptional Resistance to Aging
Aging can compromise the performance of battery casings over time. However, aluminum stands strong against the test of time. Aging performance tests have shown that maximum surface aging thickness remains below 50 μm after 20 years. The extent of aging may vary depending on geographic location and climatic zone. Most casings maintain a minimum thickness of 5mm, which constitutes less than 1% of the casing thickness. This exerts negligible impact on the casings’ mechanical performance.
The Ultimate Choice for Durability
In summary, the principal characteristics of aluminum battery casings encompass prolonged operational life, explosion resistance, and enduring resistance to aging. When it comes to ensuring the longevity and safety of your batteries, aluminum shines as the ultimate choice. Make the switch to aluminum battery casings, and experience the peace of mind that comes with top-tier quality and safety standards.
