What are Flexible Batteries?
Traditional lithium-ion batteries used in devices like smartphones, tablets, and laptops are generally rigid and inflexible. They on the other hand, use lightweight, flexible materials that allow the battery to bend and fold without losing power capacity or functionality. These types of batteries have a paper-thin form factor that makes them highly portable and easy to integrate into wearable devices, curved electronics, and other flexible or unusually shaped gadgets.

Materials and Design
They are made using novel materials and designs not seen in traditional batteries. The three main components - anode, cathode, and electrolyte layers - are very thin, sometimes only a few microns thick. Flexible plastic or polymer substrates serve as the structural base layers. Copper or silver nanowire "current collectors" replace the rigid metal contacts. Gel or solid-state polymer electrolytes allow ions to flow without leaking. Novel chemistries like lithium-ion, zinc-ion, and lithium-sulfur provide the charge-carrying reactions. All of these flexible components come together in layered "jelly roll" or interdigitated designs to deliver power without sacrificing bendability.

Potential Applications
Due to their lightweight, flexible form factor, they could enable an entirely new category of wearable consumer electronics, as well as industrial and medical applications. Some potential uses of flexible batteries include:

- Wearable devices: Smartwatches, fitness trackers, augmented/virtual reality headsets, electronic clothing, and other wearables could incorporate thin, form-fitting Flexible Battery .

- Portable electronics: Future smartphones, tablets, and laptops may feature molded, contoured designs enabled by integrated flexible battery packs.

- Medical devices: Patches, bandages, and implantable devices could utilize the conformability of them for power and data transmission.

- Industrial/commercial use: Signs, sensors, Internet of Things devices, e-textiles, and other commercial applications may employ low-cost, shape-adaptive flexible batteries.

- Transportation: Integrated into car upholstery, seat belts, tires, and other automotive/transportation components as an energy source.
