How Lithium Polymer Batteries Power Your Devices?
Lithium polymer (LiPo) batteries have improved portable power by delivering high energy density in lightweight, flexible formats. Unlike traditional cylindrical cells, LiPo batteries can use a gel-like polymer electrolyte instead of a liquid electrolyte, allowing manufacturers to create ultra-thin batteries in customised shapes that fit into modern electronic devices.
Lithium Polymer batteries work similarly to lithium-ion batteries. However, LiPo batteries consist of a cathode and an anode and use a semi-solid gel electrolyte through which lithium ions move between the cathode and the anode.
Professional Lithium Polymer Battery Solutions
The use of polymer-based components allows LiPo batteries to be made in ultra-thin designs, potentially less than 1 mm thick, and manufactured in various shapes and sizes. Li-polymer batteries are designed to store substantial amounts of energy in a compact space. Our custom-built LiPo batteries also offer low self-discharge rates and extended standby life. Unlike batteries with rigid casings, our LiPo batteries use flexible, foil-type polymer-laminated packaging, which helps reduce their overall weight.
High C-Rate Lithium Polymer Batteries
Our high-performance LiPo batteries deliver excellent power, discharge performance, and cycle life due to their stacking process. They can achieve a 150C pulse discharge, a 90C discharge for 2 seconds, a 45C continuous discharge, and 5C fast charging.
With a high discharge rate, lithium polymer batteries can also be manufactured in a wide variety of shapes and capacities to meet different application requirements.
High-Performance LiPo Battery Features
Our LiPo batteries have excellent explosion-proof performance with no fire or explosion in gun tests. Also, our team of engineers made any shape of LiPo batteries based on the actual product application requirements, and it’s operating temperature is from -50 ℃~50 ℃ or -20 ℃~80 ℃.

FAQ’s
What is Li Polymer Battery?
A Li Polymer battery (LiPo battery) is a rechargeable lithium battery that uses a gel-like polymer electrolyte and a flexible pouch design instead of the rigid metal casing used in many traditional lithium-ion batteries. This construction allows manufacturers to produce thinner and lighter batteries with customized shapes while maintaining high energy output.
How should I store a Li-Polymer battery?
A Li-Polymer (LiPo) battery should be stored at around 40% to 60% charge level, in a cool and dry place, with each cell at approximately 3.7V to 3.85V. Do not store a LiPo battery fully charged (4.2V per cell) or completely empty because both conditions can reduce battery life and increase safety risks.
Are Li-polymer Batteries Safe?
Yes, Li-Polymer (LiPo) batteries are safe when they are used with the correct charger, protection circuit, and proper handling. However, they can become unsafe if they are overcharged, physically damaged, overheated, or discharged below their safe voltage limit.
How long does a Li-Polymer battery last?
A Li-Polymer battery lasts for 300–500 charge cycles.
Can Li-Polymer batteries be recycled?
Yes, Li-Polymer batteries can be recycled although it must be taken to the authorized recycling center.
