Lithium Polymer Battery Key Features

Soft-pack lithium polymer batteries (LiPo), encapsulated in aluminum-plastic composite film, are widely used in modern consumer electronics due to their flexibility, safety, and high energy density.

Core Characteristics

1. Structural Flexibility: Aluminum-plastic film allows ultra-thin and custom-shaped battery designs.

2. Safety Performance: Soft-pack structure reduces explosion risk and improves safety under abnormal conditions.

3. High Energy Density: Provides long runtime with low self-discharge performance.

Core Advantages

1. Design Flexibility: Suitable for compact beauty devices and wearable electronics.

2. Lightweight Structure: Lower weight compared to metal-cased batteries with reliable sealing performance.

3. Long Cycle Life: Supports frequent charge and discharge cycles in daily use.

Note: External protection is recommended due to soft-pack structure.
