With the rapid surge in demand for portable and wearable electronics, there is an apparent requirement for efficient power supplies with high performance, mechanical flexibility, and long-term safety. To this context, mechanically flexible quasi-solid-state aqueous Zn-based batteries have been regarded as a class of promising energy storage devices for these portable and wearable electronics, owing to their exceptionally inherent safety of employing aqueous-based electrolytes and unique advantages of using low-cost zinc anodes. Arising from the extensive research and development over the past several years, their overall performance is becoming at least comparable with those state-of-the-art competitors, including an energy density in the range of 100–300 Wh/kg, and cycling-ability of ~2000 cycles. Although a couple of previously published review articles have focused on the hot topic addressing rechargeable aqueous Zn-based batteries, a thoroughly comprehensive overview on flexible quasi-solid-state aqueous Zn-based batteries (e.g., Zn-alkaline batteries, Zn-air batteries, and Zn-ion batteries) would be timely and essential. Herein, a concise overview on the recent advances in flexible quasi-solid-state aqueous Zn-based batteries is presented from the perspectives of rational designs for both flexible electrodes and devices, together with the challenges and opportunities that remain to be addressed, aiming to shine new light on further development of high-performance flexible aqueous batteries in the coming few years.

随着对便携式和可穿戴电子产品的需求激增，显然需要具有高性能，机械柔韧性和长期安全性的高效电源。在此背景下，由于它们具有使用水基电解质的固有固有安全性和锂离子电池的独特优势，因此，机械柔性准固态水基锌基电池被视为这些便携式和可穿戴电子产品的一类有前途的储能设备。使用低成本的锌阳极。经过近几年的广泛研究和开发，它们的整体性能至少可以与那些最先进的竞争对手相比，包括100-300 Wh / kg的能量密度以及约2000个周期的能力。例如，锌碱性电池，锌空气电池和锌离子电池）将是及时且必不可少的。本文从柔性电极和器件的合理设计观点出发，简要概述了柔性准固态水性锌基电池的最新进展，并提出了尚待解决的挑战和机遇，旨在在未来几年内进一步发展高性能柔性水电池的新亮点。
