What is a Lithium Polymer Battery?
A lithium polymer (LiPo) battery is a type of rechargeable battery that uses a polymer electrolyte instead of a liquid electrolyte. LiPo batteries are known for their lightweight design, high energy density, and flexible form factors, making them ideal for applications where size and weight are critical. Let’s explore some important aspects of LiPo batteries:
Lithium Polymer vs. Lithium-ion Battery
- Form Factor:LiPo batteries are typically more flexible and can be made in a variety of shapes and sizes, while lithium-ion (Li-ion) batteries usually come in rigid cylindrical or prismatic forms.
- Energy Density:Li-ion batteries tend to have higher energy density than LiPo batteries, but LiPo batteries offer better flexibility and lighter weight, which is ideal for portable applications.
- Safety:LiPo batteries are generally safer than Li-ion batteries, as they are less prone to leaking or exploding when damaged.
LiPo Battery Storage
LiPo batteries should be stored in a cool, dry environment and maintained at about 50% charge to ensure long lifespan and prevent capacity loss. Storing batteries at full charge or completely discharged can lead to degradation.
Safety of LiPo Batteries
LiPo batteries are equipped with built-in safety features, including Protection Circuit Boards (PCBs) that safeguard against overcharge, over-discharge, and short circuits. This ensures safe operation during use and charging.
LiPo Charge Rate
LiPo batteries can charge at high rates, typically 1C to 5C depending on the battery’s design. Some specialized LiPo battery models support fast charging rates up to 10C, making them ideal for high-performance applications where quick recharge times are required.

Lithium Polymer Battery – Frequently Asked Questions
Lithium polymer batteries use a flexible aluminum-plastic pouch and gel-like electrolyte, making them lighter, thinner, and safer than traditional cylindrical or prismatic lithium-ion batteries.
We can produce ultra-thin designs down to 0.4mm. Common customized thicknesses range from 0.8mm to 10mm depending on capacity and structure.
Yes. The pouch structure allows pressure release through swelling rather than explosion. They also include multiple protection circuits and comply with ROHS, UN38.3, and GB standards.
Absolutely. We support custom shapes, voltage levels, capacities (40mAh to 20Ah), electrode tab locations, and even complete module or housing designs based on your device requirements.
Under standard charge/discharge conditions, the cycle life exceeds 500 cycles. With proper management, the actual life span can be extended even further.
