What are the advantages of soft pack lithium batteries, 18650 manufacture aluminum shell lithium batteries, and steel shell lithium batteries?

There are three types of lithium batteries on the market at present: soft shell batteries, aluminum shell batteries, and steel shell batteries. There are three types of lithium batteries: soft lithium batteries, aluminum lithium batteries, and steel lithium batteries. Which of them is better, which have advantages over others? Let's look at Gepp.

The advantages of soft pack lithium batteries

In the case of safety risks, the soft lithium battery will not explode, only explode or rupture due to its aluminum-plastic packaging.

The soft pack lithium battery is lighter than the aluminum shell lithium battery by about 20%.

Soft-coated lithium batteries have a higher capacity than aluminum shell batteries of the same size.

There is currently no internal resistance above 5 m in the soft pack lithium battery, which greatly reduces self-consumption.

The battery's cycle life is longer, and its attenuation of 100 cycles is 4% to 7% less than that of aluminum shells.

Flexible design: the shape of the soft pack lithium battery can be customized to meet the needs of different customers, and various irregular soft pack lithium batteries can be manufactured. In general, aluminum shells can be 4mm thick, but soft bags can be 0.5mm thick.

In high application research fields, such as 3C consumer enterprise electronic information products, a soft pack lithium battery is more suitable for portable, space or different thickness design requirements.

Secondly, aluminum shell lithium batteries have several advantages

Battery aluminum shells have high specific strength, specific modulus, fracture toughness, fatigue strength, and corrosion resistance.

It is widely used in aviation, aerospace, high-speed trains, machinery manufacturing, transportation, and chemical industries because of its low density, nonmagnetic, stable alloy, smaller than magnetic field resistance, good air tightness, and attenuation of induction radiation at low temperatures.

In addition, the surface treatment of the battery aluminum shell is important through electrostatic spraying, and its color is also very rich, commonly beige, dark gray, black, and military green.

In addition, the aluminum shell of the battery has the advantage of being light weight and durable.

A battery aluminum shell's plastic ability is strong, its production technical performance is better than other profiles, it has a good casting performance, and it has a good development advantage.

In addition, the aluminum shell of the subcontinent battery undergoes cold and hot treatment, providing strong corrosion resistance. This makes aluminized batteries safer.

The shell is also a light alloy and contains many metal elements. Its chemical properties are stable, non-magnetic, recyclable, so it is an easy metal to recycle.

The third advantage of steel shell lithium batteries

In the early days of cylindrical lithium batteries, steel shells were widely used. Steel shell batteries have the following advantages:

In comparison to aluminum shell material, steel is much more durable and compressible. The steel shell-column lithium battery has reached a new level of safety after the safety device has been placed inside the battery cell as a result of the design and structure optimization by various manufacturers. Steel shells are currently used to carry most laptop batteries.

The above problem is the advantages of soft pack lithium battery, aluminum shell lithium battery, steel shell lithium battery to introduce, in short, soft pack lithium battery, aluminum shell lithium battery, steel shell lithium battery has an advantage in their own ability, and we can choose the process according to the actual needs of students.
