In depth analysis of New energy aluminum battery cases: performance, reliability, and development prospects

In the field of primary batteries, New energy aluminum battery cases have become highly representative products due to their excellent comprehensive performance. Although its commercialization process was later than other lithium battery systems, it quickly rose with unique technological advantages and has now developed into one of the mainstream lithium battery series worldwide. This type of battery case is widely used in civilian fields such as pacemakers and CMOS backup power supplies, and also occupies an important position in military equipment such as shells, missiles, and fuses.

Its reliability is directly related to the security and stability of the application scenario. This article systematically reviews the excellent performance, application status, core reliability issues, and improvement research directions of Automotive battery aluminum cases, comprehensively presenting the core industry knowledge of the product.

The reason why New energy aluminum battery cases can be widely applied in multiple fields is mainly due to the following outstanding performance advantages:

1. Leading voltage level: Among all battery product systems, LiSOCl ₂ batteries have excellent voltage performance. Its single cell open circuit voltage can reach 3.6-3.7V, far exceeding most similar batteries, and can provide stable power support for high-voltage demand scenarios.

2. Strong voltage stability and high load accuracy: This battery has extremely stable voltage output and good load voltage accuracy. When the discharge current rate is 1mA/cm ², the voltage can be stably maintained at 3.3V, and the voltage remains stable in more than 90% of the battery energy discharge range, effectively ensuring the stable operation of electrical equipment.

3. Wide working temperature range: Aluminum cases for new energy cars have strong environmental adaptability, with a working temperature range of -55 ℃ to+85 ℃. Whether in extremely low temperature cold environments or high temperature hot scenes, its performance can remain excellent, suitable for special application environments such as high altitude, polar regions, and high-temperature equipment.

4. Long storage life and low self discharge rate: The self discharge rate of this battery is extremely low, less than 1%. This advantage stems from the formation of a LiCl protective film on the surface of the electrolyte, which keeps lithium highly stable in the electrolyte. With a good battery sealing structure, the storage life of LiSOCl ₂ batteries can reach 10 years, which can meet the application needs of long-term backup power supply.

Currently, the product system of Lifepo4 soft pack cell is becoming increasingly sophisticated, with a diverse range of models and types, covering various structural forms such as button, cylindrical, and rectangular.

Each structure contains dozens of specific models, with a wide range of capacity coverage, from a few milliampere hours to hundreds of thousands of milliampere hours, which can accurately match the electricity needs of different scenarios. From the perspective of application fields, low to medium rate LiSOCl ₂ batteries are the mainstream products in the current market.

In the civilian field, Rechargeable aluminum shells provide stable power for precision electronic devices such as pacemakers and CMOS backup power supplies; In the military field, they are the core power components of equipment such as shells, missiles, fuses, and landmines, and have important strategic significance.

The storage and reliability failure of LiSOCl ₂ batteries is a complex process caused by multiple factors working together. Solving reliability issues is the key to expanding it to a wider range of application scenarios. In the future, with the continuous updating and iteration of sealing materials, the continuous upgrading of the connection process between stainless steel and sealing materials, the gradual optimization and improvement of electrolyte formulas, and the reasonable control of production costs, the reliability and safety of EV car battery shells will be further improved. With excellent voltage performance, high specific energy, wide temperature adaptability, and long lifespan, Pack aluminum housing is expected to make greater breakthroughs in precision electronics, high-end equipment, and extreme environmental applications, with broad market application prospects.
