Flexible Lithium Polymer Battery

Strengths

• Gel polymer electrolyte
• Rapid movement of lithium ion
• No overheating
• High energy density
• Low internal resistance
• Stable even with bending fatigue

Benefits

1. FLEXIBILITY

J.Flex can be bent or rolled to enhance the flexibility of next generation devices. From IT to healthcare and fashion, J.Flex supports a range of industries that are using advanced technologies to add new design, comfort, and efficiency to their devices.

The test below tracks the charge and discharge performance of batteries in two different states:

1. Non-bending

2. Dynamic bending (10,000 bends from flat to 20mm in radius)

Even with constant dynamic bending, J.Flex performed at the same efficiency and capacity as the non-bending baseline level

2. DESIGN

Creative designs are often hindered due to lack of components that support the designer’s vision for the product.
With J.Flex, a new level of customization is possible.
A designer can now use new shapes and sizes not otherwise possible without minimizing performance.
This brings out the design’s full potential, and enables entirely new types of devices that are more functional, discreet, and streamlined.

3. PERFORMANCE

J.Flex ensures outstanding performance for any device.

The tests below are based on a J.Flex cell with the following specifications:

• High Rate Cycle (1.0c Charge & Discharge)
• Charging Rate
• Discharge Rate

4. SAFETY

J.Flex is in compliance with international standards to ensure safety for all applications.
