A flexible battery market involves a cell stack made out of various unit cells and an outer packaging for fixing the cell stack. Every one of the various unit cells is made out of a positive cathode, a negative anode, and an electrolyte layer situated between the negative terminal and the positive terminal. These miniaturized scale parts are typically mounted on flexible substrates, for example, metal foils, polymer films, paper sheets, or elastic surfaces. Such flexible substrates offer the possibility to create battery items that curve and stretch, giving a more extensive scope of battery plans and applications for vitality stockpiling gadgets. The worldwide flexible batteries market is relied upon to extend at a critical pace during the estimate time frame, driven by developing mindfulness and expanding usage of wearable electronic gadgets. The worldwide flexible batteries market was esteemed at around US$ 250.0 Mn in 2017 and is foreseen to grow at a CAGR of around 30.0% somewhere in the range of 2018 and 2026.
Flexible batteries are stretchable, bendable, and lightweight in nature and easy to use in intricate products with limited internal space. These batteries are widely used in wearable electronic devices such as smart glasses, smart watches, fitness bands, smart video/photo devices, and smart textiles, due to their characteristics. As the flexibility feature enables the battery to be folded, rolled, cut, and adapted to complement any shape of the product, the demand for flexible batteries is expected to increase in electronic applications in the near future. IoT devices are likely to require battery attributes such as re-chargeability with high-storage capacity and wireless connection to external power supplies in the near future.
Wearable electronic devices powered by an IoT medium are gaining popularity, as they have features such as instant interoperability, profile management, data collection, notifications, and security. Increase in the rate of adoption IoT-enabled wearable electronic devices for monitoring, diagnosing, gauging, navigating, and tracking applications is anticipated to boost the demand for flexible batteries in the next few years. Flexible batteries sustain large strain deformations including bending, twisting, stretching, and compressing, without any effect on the output of the system. These properties of flexible batteries enable their widespread use in health care and medical applications. Medical and cosmetic patches powered by flexible batteries are employed to monitor and track the user’s brain, heart and muscle activities.
