Custom Lithium-ion Polymer Battery Capabilities
Features of lithium-ion polymer cells
- Standard Lithium Polymer Battery Cells
1. Stable low-rate discharge
Supports stable discharge at ultra-low rates, such as 0.1C, helping maximize battery life and extend device runtime.
2. Flexible customization
Can be customized in shape, size, capacity, and other specifications to meet different product design requirements.
- High-Voltage Lithium Polymer Battery Cells
Energy density is typically 15–25% higher than conventional lithium polymer batteries. This provides longer runtime, or allows the battery to take up less internal space while maintaining the same runtime, giving product designers more flexibility. It is especially suitable for wearable devices and other compact products with limited internal space.
A higher average voltage platform and more stable voltage drop help prevent sudden power drops, resulting in more consistent device performance.
- High-Rate Lithium Polymer Battery Cells
Supports discharge rates of up to 70C, making it ideal for drones, power tools, and other high-power devices.
The discharge rate can be customized based on application requirements. By comparison, cylindrical battery cells generally support a maximum discharge rate of around 10C.
- Semi-Solid Lithium-Ion Polymer Battery Cells
Ultra-high energy density
The most outstanding feature is its ultra-high energy density, which can reach up to 350 Wh/kg. Compared with traditional lithium polymer batteries at around 150–220 Wh/kg, it significantly improves runtime and helps maximize device operating time.

How do you test cell safety, consistency, and cycle life?
+
-
We test lithium polymer cells for capacity, voltage, internal resistance, safety performance, consistency, and cycle life. Standard tests may include charge/discharge testing, overcharge, over-discharge, short-circuit, temperature, and aging tests.
Can you ship lithium polymer batteries internationally?
+
-
Yes. We can ship lithium polymer batteries internationally by air, sea, or express courier, depending on battery type, quantity, and destination. Required shipping documents such as MSDS and UN38.3 can be provided when available.
