Introduction
The flexibility and portability of electronic equipment brings a lot of convenience, but traditional energy storage devices are relatively rigid and cannot be integrated with modern flexible electronic equipment:
Therefore, flexible nano energy storage devices based on nanomaterials or nanotechnology have emerged: Use of nanomaterial substrates (such as carbon nano
tubes, graphene, carbon fibers, low-dimensional nanostructured materials and corresponding composite materials, etc:), combined with nanostructured active materials, flexible nanoscale energy storage
The device can improve the flexibility of the device on the basis of obtaining the advantages of energy storage, and realize a fully flexible integrated electronic system:
The application field and service life of flexible nano-energy storage devices depend on the reliability of energy storage performance during flexible deformation: Flexibility is its unique,
important evaluation index: Monitoring energy storage performance changes under bending conditions is a common method to evaluate its flexibility: However, the current bending test
The specific process and evaluation parameters are not uniform, which is not conducive to the accurate evaluation and mutual comparison of flexible nano energy storage devices: The establishment of corresponding standard methods
It is of great significance to the performance comparison and design and development of flexible nano energy storage devices:

3 Terms and Definitions
GB/T 30544:1, GB/T 30544:4 and the following terms and definitions apply to this document:
3:1
Manufactured based on nanomaterials or nanotechnology, energy storage devices that can maintain work under repeated bending, twisting and other deformation conditions:
3:2
bending strain bendingstrain
Induced by bending, it indicates the degree of bending deformation of the flexible nano-energy storage device, and the length change rate of the outer/inner surface layer of the device:
3:3
Bending test bending test
Control the bending radius and bending angle, make the flexible nano-energy storage device undergo a certain degree of repeated bending strain, and observe the energy storage performance:
A test that keeps the situation:
3:4
Bending angle bendingdegree
The angles at both ends of the flexible nano energy storage device change along the bending direction:
Note: The bending angle is the external angle formed by the tangent intersection of the two terminal contact points of the device to be tested and the bending mold, and is also equal to the angle between the two terminal contact points and the bending angle:
The angle formed by the line connecting the center of the mold circle:
3:5
Bending times bendingcycle
The number of times a flexible nano energy storage device completes a bending cycle:
Note: A bending cycle refers to the process of the device under test from the initial state → bending state → initial state:
3:6
bending height bendingheight
The height in the vertical direction of the two ends of the part containing the electrode material in the flexible nano energy storage device:
