Abstract

Highlights

An integrated conjugated microporous polymer composite electrode (C₄N/rGO) with high conductivity, large specific surface area and good solvent resistance was prepared by in-situ growth.
An antifreeze alkaline electrolyte (0.1 DMSO/2 M NaOH) was developed to broaden the operation temperature zone and voltage window of the aqueous alkaline battery.
The prepared aqueous alkaline battery exhibits a high energy density (147.3 Wh Kg⁻¹ at 25 °C), outstanding long cycling stability and excellent wide-temperature-range performance (−70 to 45 °C).

期刊介绍： Nano-Micro Letters is a peer-reviewed, international, interdisciplinary, and open-access journal published under the SpringerOpen brand. Nano-Micro Letters focuses on the science, experiments, engineering, technologies, and applications of nano- or microscale structures and systems in various fields such as physics, chemistry, biology, material science, and pharmacy.It also explores the expanding interfaces between these fields. Nano-Micro Letters particularly emphasizes the bottom-up approach in the length scale from nano to micro. This approach is crucial for achieving industrial applications in nanotechnology, as it involves the assembly, modification, and control of nanostructures on a microscale.
