Abstract

The concept of fiber-type batteries has attracted considerable interest due to the great potential applications for flexible, adaptive, and wearable energy-storage textiles. Aqueous Zn–MnO₂ batteries hold the advantages of low cost, intrinsic safety, high capacity, and high energy density, which could be a very promising candidate for wearable electronics. However, achieving high stability and performance in fiber-type Zn–MnO₂ batteries remains challenging. Herein, we demonstrate a rechargeable cable-like Zn-ion battery that utilizes MnO₂/carbon nanotube (CNT) hybrid fiber cathodes synthesized via in-situ redox reaction and bio-derived solid-state electrolytes. The assembled battery exhibits a high capacity of 204 mAh cm⁻³ and long-term cycling stability with 77 % capacity retention after 450 cycles at 2 mA cm⁻¹. This cable-type battery provides new opportunities for portable and wearable electronics.

电缆状可充电固态锌离子电池

纤维型电池的概念已经引起了相当大的兴趣，因为它在柔性、自适应和可穿戴储能纺织品方面具有巨大的应用潜力。锌-二氧化锰水溶液电池具有成本低、本质安全、容量大、能量密度高等优点，是一种非常有前途的可穿戴电子产品。然而，在光纤型锌-二氧化锰电池中实现高稳定性和高性能仍然具有挑战性。在此，我们展示了一种可充电的电缆式锌离子电池，该电池利用MnO2/碳纳米管（CNT）混合纤维阴极，通过原位氧化还原反应和生物衍生的固态电解质合成。组装的电池具有204 mAh cm - 3的高容量和长期循环稳定性，在2 mA cm - 1下循环450次后，容量保持率为77%。这种电缆式电池为便携式和可穿戴电子产品提供了新的机会。
