Abstract

Highlights

The critical bimetallic phosphide layer (CBPL) exhibits high electrical conductivity and forms heterostructures with NiCo-layered double hydroxide (NiCo-LDH), improving the electrical conductivity of the hybrid cathode (NiCo-P1.0).
CBPL facilitates OH⁻ adsorption and synergizes with NiCo-LDH in electrode reactions, delivering extra energy.
NiCo-P1.0 cathode delivers 286.64 mAh g⁻¹ at 1C with a retention of 72.22% at 40C. The assembled NiCo-P1.0//Zn battery achieves energy density/power density (503.62 Wh kg⁻¹/18.62 kW kg⁻¹). The flexible quasi-solid-state pouch cell maintains stable output after deformation.

关键双金属磷化层实现柔性准固态锌电池的快速电子转移和额外能量供应

关键的双金属磷化物层（CBPL）具有高导电性，并与NiCo-LDH形成异质结构，提高了杂化阴极（NiCo-P1.0）的导电性。CBPL促进OH -吸附，并在电极反应中与NiCo-LDH协同作用，提供额外的能量。NiCo-P1.0阴极在1C时提供286.64 mAh g⁻¹，在40℃时保留率为72.22%。组装后的NiCo-P1.0//Zn电池达到503.62 Wh kg−1/18.62 kW kg−1的能量密度/功率密度。柔性准固态袋状电池在变形后保持稳定的输出。

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.
