A new design of lithium ion batteries with tunable mechanical properties has been developed. Depending on the material design of the battery components, the battery can range from elastic to structurally rigid. Elastic battery electrodes have been fabricated by utilizing elastic polymer binders in the electrode construction.
In addition, cable-based LIBs usually use fibrous or two-dimensional carbon materials with good mechanical properties and continuous electronic conduction to prepare flexible electrodes so that the active materials can better adhere to the carbon materials to adapt to the deformation of cable-type batteries in practical applications .
The battery of a single energy storage unit can use CNT fiber springs as electrodes, enabling the battery to possess self-supporting and stretchable properties . After 9000 cycles, the spiral-structured lithium battery still maintains stable stretching durability and exhibits good voltage retention under 1300% stress deformation .
Meng et al. designed a flexible lithium battery inspired by the Deoxyribonucleic acid (DNA) double helix structure. This spiral-structured battery is mainly composed of multiple energy storage units and some stress-buffering dimples (Figure 9 f) .
First, the types of key component materials and corresponding modification technologies for flexible batteries are emphasized, mainly including carbon-based materials with flexibility, lithium anode materials, and solid-state electrolyte materials.
When an elastic polymer matrix is used, the battery electrode becomes elastic and can serve as the starting point for the fabrication of an elastic battery. When a structural polymer matrix is reinforced with fibers, a battery with load bearing capabilities can be designed.
