Research Progresses and Challenges of Flexible Zinc Battery

Abstract

Flexible zinc batteries have great potential in wearable electronic devices due to their high safety, low cost, and environmental friendliness. In the past few years, a great deal of work on flexible zinc batteries has been reported, with exciting results. Therefore, many solutions have been proposed in electrode design and electrolyte preparation to ensure the desired flexibility without sacrificing the capacity. This paper reviews the recent progress of flexible zinc batteries. We discuss the differences between various anode materials, cathode materials, and electrolytes, introduce the differences of electrode preparation methods of active materials on flexible substrates and their influence on the performance of the battery. Finally, the challenges and future research trends of flexible zinc batteries in capacity and mechanical properties are pointed out.

Essential data for industrially relevant development of bifunctional cathodes and biopolymer electrolytes in solid-state zinc–air secondary batteries

“…Nowadays, an interesting and increasing academic field is that of flexible ZABs, 6,164,165 characterized by a multidisciplinary approach where miniaturization, electrochemistry, engineering design, physics, and materials science need to cooperate. Flexible ZABs, primary the most, but also electrically rechargeable, using gelled electrolytes and advanced zinc anodes (powder, paste, and 3D-printed structured foils) could break the market of flexible/ wearable electronics or the disposable/wearable non-invasive devices for sensing/detection/biomedical applications.…”

“…The niche of small and flexible secondary ZABs for portable devices appears to be more advanced than stationary applications. There is voluminous literature on the topic; [164][165][166][167]169 however, higher TRL values seem hard to be achieved in real applications, and reliable commercial products, at any scale, size, or price, are missing, to the best of authors' knowledge.…”

Toward Sustainable Wearable Electronic Textiles

“…One of the biggest challenges in developing wearable electronic devices is the requirement for flexibility, lightweight, thinness, safe and portable energy storage devices. To this end, we may draw inspiration from zinc ion batteries, which have demonstrated excellent potential for wearable electronics applications because of their safety, economical, and environmental friendliness . Zn dissolution rates for aqueous system and biofluids have been reported as 1.7 nm day –1 and 7.2 nm day –1 , respectively.…”
