Why do we need stretchable batteries & supercapacitors?
The increasingly intimate contact between electronics and the human body necessitates the development of stretchable energy storage devices that can conform and adapt to the skin. As such, the development of stretchable batteries and supercapacitors has received significant attention in recent years.
How can a battery be flexible?
The flexibility of batteries can be achieved by flexible substrates such as flexible foil or wire in the deformed region. Similar to PAMAD, the thickness of the deformation area is much thinner than the active material area to keep the balance between high energy density and flexibility.
Which materials can be used for stretchable electrochemical energy storage?
A wide range of materials are covered for each strategy, including polymers, metals, and ceramics. By comparing the achieved electrochemical performance and strain capability of these different materials strategies, we allow for a side-by-side comparison of the most promising strategies for enabling stretchable electrochemical energy storage.
How does the structural design of a battery affect its flexibility?
The structural design of the battery significantly influences its flexibility. Variations in the structural designs of the batteries result in them experiencing different forces during deformation, including the location of the force and the direction and magnitude of the stress.
Why are flexible batteries important?
This perspective holds significant relevance for the advancement of flexible batteries. Flexible batteries can withstand harsh conditions and complex deformations through effective structure design while maintaining stable electrochemical performance and an intact device during the strain yield process.
Why are flexible batteries bending angles important?
Flexible batteries for wearable applications probably undergo bending deformation at different angles, so bending angles are preliminarily used to reflect the flexibility of batteries with different structures.
