How do soft pack lithium batteries, aluminum shell lithium batteries, nmp recovery system and steel shell lithium batteries differ?

Currently, lithium batteries have three basic types: soft shell lithium batteries, aluminum shell lithium batteries, and steel shell lithium batteries. n methyl 2 pyrrolidone solvent So soft lithium batteries, aluminum lithium batteries and steel lithium batteries which is good, soft lithium batteries and aluminum lithium batteries and aluminum lithium batteries steel shell have what advantages? Let's look at Gepp.

First, let's look at the advantages of soft pack lithium batteries

In the case of safety risks, nmp chemical the soft lithium battery will not explode because it is packaged with aluminum-plastic film.

A soft pack lithium battery is about 20% lighter than an aluminum shell battery.

The capacity of soft-coated lithium batteries is up to 10% higher than that of aluminum shell batteries of the same size.

A low internal resistance of the soft pack lithium battery reduces the self-consumption of the battery greatly and reduces its self-consumption.

The battery has a longer cycle life, and its attenuation of 100 cycles is 4% to 7% less than that of an aluminum shell.

Flexible design: the shape of the soft pack lithium battery can be customized according to customer requirements to meet the requirements of different customers, and various irregular soft pack lithium batteries can be produced. An ordinary aluminum shell can only be 4mm thick, while a soft bag can be 0.5mm thick.

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

Secondly, aluminum shell lithium batteries have several advantages

An aluminum battery shell has a high specific strength, specific modulus, fracture toughness, fatigue strength, and corrosion resistance.

As a result of its low density, nonmagnetic, stable, small magnetic field resistance, good air tightness and induction radiation attenuation at low temperatures, aluminum alloys are widely used in aviation, aerospace, high-speed trains, machinery manufacturing, transportation, and chemical industries.

Electrostatic spraying is used to treat the battery aluminum shell, and the color is generally beige, dark gray, black, or military green.

The aluminum shell of the battery has the advantages of aluminum alloy, which is lightweight and durable.

In addition, the battery aluminum shell has a high plastic ability, a good casting performance, and a good development advantage in production.

As a result of the cold and hot treatment process of the aluminum of the subcontinent battery, the aluminum shell is highly corrosion resistant, making aluminized batteries safer.

The shell also has good ductility, making it a light alloy and contains many metal elements. Its chemical properties are stable, non-magnetic, recyclable, and it is a good recyclable metal material.

The third advantage of steel shell lithium batteries is their durability

Among the main advantages of steel shell early cylindrical lithium batteries are:

Compared to aluminum shell materials, steel is much more physically stable 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 following the design and structure optimization of various manufacturers. Steel shells are currently used as carriers for 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 each has its own advantages, so we can choose the process according to the actual needs of students to choose.
