Curved Lipo Battery Production
Thanks to the soft aluminum film, the curved lipo battery can be bent into different angles to fit in different constrained spaces. This ALF shaping video discovers the soft aluminum film automatic production process to view the flexibility of the lipo batteries, which enables people to fully understand the silver surface of the round lipo batteries.
Curved Lipo Battery Manufacturer in China
Curved lipo battery is a custom lipo battery in a special curved shape as a result of the polymer-electrode and soft aluminum film with pre-formed bent shape. Through years of research and testing, VTCBATT is proud to announce that we can bend the lipo battery in different curved degrees as per product demand, which is in a space-constrained curved design.
Curved lipo batteries are widely used in smartwatches, fitness trackers, smart AI glasses e.g meta Ray-Ban, hearing aids, VR/AR headsets, compact IOT sensors to providea stable and reliable power supply to these modern and sleek electronic devices.

Key Features of Curved lipo batteries
Curved lipo batteries are fully customized in both different sizes and different angles, enabling the innovation of modern consumer electronics, such as AR/VR glasses, smart rings, AI glasses, smartwatches, fitness trackers, and VR/AR headsets.
The curved lipo batteries use 100% Lithium cobalt as the anode, graphite as the cathode, and nano-ceramic diagram as the separator, which ensures the super performance of the battery. Curved Lipo battery can even maintain a 3.8V higher voltage platform to ensure an excellent discharge curve than a normal lipo battery.
Lipo battery curved has much stricter requirements in safety and reliability than a normal lipo battery. Even it is bent, it should be assembled with a protection circuit(PCB) to maintain ultimate safety to avoid overcharge,overdischarge, overcurrent, and overtemperature.
Applications of curved lipo battery
Advanced Consumer ElectronicsThe curved lipo battery market is small, mostly restricted to VR/AR Glasses, AI glasses, Smart rings, VR/AR headsets, and smartwatches, which is very space-constrained and special design.
Automotive key fobs&SensorsThe automotive interiors, such as key fobs or sensors, are provided with curved designs, which can only be installed with the curved LiPo battery. The rechargeability of the curved lipo battery enables the key fobs and sensors great convenience without repeated replacement.
Medical devicesMedical devices , such as implantable devices or external wearables, are in space-constrained and curved shapes to conform to the body. The curved lipo batteries are the ideal choice for these medical devices and bring great comfort to the patients.

A: The main difference of curved lipo battery and flat lipo battery below:
Shape Difference
Curved lipo battery is bent and contoured. While a flat lipo battery is rectangular, square shape.
Cost difference.
Due to special materials and manufacturing processes, a curved lipo battery is much higher cost than a normal flat lipo battery.
Handling Caution.
Curved lipo battery requires special handling caution to avoid potential point stress, fatigue, and delamination; otherwise, it will be broken and damaged.
Flat lipo battery can be handled normally, which is not easy to break or damage.
Installation
Due to the curved shape and bent angles, the curved lipo battery must be mounted precisely; otherwise, it will be damaged and broken easily.
While the flat lipo battery just needs normal operation without much care.
Lead time
Curved lipo battery takes 35-40 days, a longer time than the normal flat lipo battery, because the curved lipo battery takes special care in manufacturing, and the curved lipo battery market demand is very few. While flat lipo battery has very huge demand with plenty of stock, flat lipo battery can support fast delivery within 7-20 days.
Availability
It’s very easy to get the flat lipo battery in the normal market, while the curved lipo battery is only custom-made for specific OEM customers, who manufacture the devices.
Safety Risks
Due to the special curve shape, curved lipo battery is subject to stress and improper mounting, which can lead to lots of safety risks, while flat lipo battery doesn’t have this kind of risk due to the curved shape.
A: The handling of curved lipo battery takes special care; otherwise, the battery will be easily damaged.
- Don’t bend or stress the battery with a clear warning.
- Mount the battery in the correct position.
- Store the battery in a cool environment to avoid high temperature exposure.
- Keep the battery voltage above 3.7V before long-term storage to avoid over-discharge.
- Recharge the battery before 20% SOC to extend the battery lifespan.
A: Identify the suitable size to place the PCB in the curved lipo batteries.
If the size is sufficient or flat, you can use the normal standard flat PCM.
If the size is curved, the flexible printed circuit(FPC) can be precisely designed in the curved size, which is 2-3 times higher cost than na ormal standard PCM.
A: Lipo battery has a discharge curve and a charge curve. The discharge curve shows the battery voltage against the discharge time and current, while the charge curve shows the battery voltage against charge time and current.
A: A curved lipo battery is a type of rechargeable lithium polymer battery, which is bent at different angles. The composition of a curved lipo battery is the same as normal lipo battery.
A: If the curved battery is swollen, the battery is bad, and you can’t use it anymore.
Don’t throw away the battery casually, which will cause environmental pollution.
Package the curved battery in a plastic bag separately.
Find the battery recycling bins nearby. Most supply chain stores, such as Walmart , Home Depot, and Best Buy, have wasted battery recycling trash.
A: Yes. You can charge the device with the curved lipo battery, but do only use the specific charger provided by the device manufacturer or an approved replacement.
A: Under correct handling and operation, the curved lipo battery has the same lifespan as the flat lipo battery. The shape doesn’t affect the lifespan, as they use the same materials.
A: No. It’s prohibited to bend or flex a curved Lipo battery after it’s made, which will damage the battery. The curved lipo battery is just curved, but not flexible to any size after it is made.
A: Curved lipo batteries use 100% LiCoO2 as the cathode, graphite as the anode,polymer-based electrolyte, and polyolefin(PE/PP) film as a separator. The soft aluminum film enables the lipo batteries to be bent.
