What is a Lithium Polymer Battery?
A Lithium Polymer battery, often abbreviated as LiPo battery, is a type of rechargeable lithium-ion battery that uses a polymer electrolyte instead of a liquid one. Known for its high energy density, slim form factor, and flexible design capabilities, LiPo technology is widely adopted in industries where compact, lightweight, and custom-shaped power solutions are essential. For B2B buyers—especially OEMs, system integrators, and product developers—it provides the ideal combination of performance, design flexibility, and cost-efficiency.
How LiPo Batteries Compare to Other Battery Technologies
Compared to traditional cylindrical lithium-ion batteries or bulky lead-acid batteries, LiPo batteries stand out due to their versatile packaging and lightweight structure. They can be manufactured in ultra-thin, compact formats without compromising energy output. This makes them particularly suitable for space-constrained devices such as drones, medical devices, handheld electronics, IoT products, and robotics. With consistent discharge characteristics, low self-discharge rates, and fast charging capabilities, lithium polymer batteries ensure stable and reliable operation across a wide range of professional applications.

Lithium Polymer Battery – Frequently Asked Questions
What is the main difference between lithium polymer and traditional lithium-ion batteries?
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.
How thin can a lithium polymer battery be?
We can produce ultra-thin designs down to 0.4mm. Common customized thicknesses range from 0.8mm to 10mm depending on capacity and structure.
Are lithium polymer batteries safe?
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.
Can I fully customize the shape and capacity of the battery?
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.
How long is the cycle life of a lithium polymer battery?
Under standard charge/discharge conditions, the cycle life exceeds 500 cycles. With proper management, the actual life span can be extended even further.
