Product Description:

The soft pouch Battery—also known as a lithium polymer battery (Li-Po)—uses a flexible,  foil-type polymer casing rather than the traditional metal shell found in cylindrical or prismatic batteries.    This  construction allows for thinner,  lighter batteries that can be customized in shape and size to fit into the smallest devices while still delivering high  power and stable voltage output.

With optimized chemical formulations and advanced cell design,  our soft pouch lithium batteries provide reliable operation, excellent thermal performance,  and long life cycles.    These batteries are produced in a clean environment using state-of-the-art equipment and  undergo rigorous testing to ensure consistency, safety, and durability.

Product Advantages:

Pouch batteries are another form of battery packaging compared to traditional steel shell batteries. Soft-pack batteries are mainly composed of aluminum-plastic film, positive and negative electrode sheets, separators, electrolytes and conductive materials, etc. They have the following advantages:

1. Lightweight and convenient: Pouch batteries use flexible packaging, which is lighter and smaller in size compared to traditional steel shell batteries, making them more flexible in design and conducive to the lightweight and compact design of products.

2. High safety: Soft-pack batteries are packaged with aluminum-plastic film, which has excellent heat resistance, wear resistance and impact resistance. At the same time, the aluminum-plastic film packaging also has high safety, which is conducive to avoiding the risk of battery fire and explosion.

3. High energy density: The internal structure of pouch batteries adopts a coiled design, which ensures a high charging density. Therefore, pouch batteries can achieve a high energy density and battery capacity, providing longer-lasting and longer battery life for electronic products.

4. Low internal resistance: The coiled structure in pouch cells keeps the distance between the positive and negative electrode sheets relatively short, resulting in a relatively low internal resistance of the battery. This is conducive to rapid discharge and enhances the battery's output power.

5. Environmental friendliness: Soft-pack batteries are packaged with aluminum-plastic film, generating relatively less waste during production and processing, having a smaller impact on the environment and helping to reduce pollution.

Soft-pack batteries have the advantages of being lightweight, convenient, highly safe, having a high energy density, low internal resistance and being environmentally friendly, which makes them have broad application prospects in electric vehicles, portable electronic products, energy storage systems and other fields.

Common FAQs:

What is the difference between soft pouch and cylindrical lithium batteries?

Soft pouch batteries are lighter, thinner,  and more flexible in shape compared to rigid cylindrical cells.    They are ideal for devices with tight space  constraints.

Are your soft pouch batteries customizable?

Yes.    We provide custom design options in capacity, voltage, shape,  and connector type to match your product requirements.

How safe are soft pouch batteries?

Our batteries come with built-in protection circuits and are tested for overcharge, short-circuit,  and thermal stability.    All batteries meet global safety standards.

Do these batteries have certification for export?

Yes.Our products meet CE, RoHS, UN38.3 and MSDS requirements.    UL certification can also be provided upon request.

What’s the typical lead time for orders?

For standard models, we can ship within 5–10 business days.    Custom models may take 2–3 weeks.

Can I order a sample before bulk purchase?

Absolutely.    We encourage sampling and testing before placing large orders to ensure compatibility and performance.

What’s the storage requirement for soft pouch batteries?

Store in a dry, cool place, ideally between 20–25°C.    Avoid exposure to direct sunlight or extreme temperatures.

What’s the charging protocol for soft pouch lithium batteries?

Use a dedicated lithium-ion/polymer battery charger.    Avoid overcharging or deep discharging.
