Abstract

Highlights

The double-network binder shows excellent adhesive and self-healing abilities, which help suppress electrode volume expansion and stabilize the electrode interface upon cycling.
This binder induces a Li₃N/LiF-rich solid electrolyte interface layer, which can suppress continuous electrolyte decomposition.
Superior electrochemical performance can be achieved in Si/Li half cells and LiNi_0.8Co_0.1Mn_0.1O₂/Si full cells, even with a high loading of Si electrode.

entenon护套启发的双网络粘合剂使硅电极具有优越的循环性能

双网粘结剂具有良好的粘结和自愈能力，有助于抑制电极体积膨胀，稳定电极界面。该粘结剂诱导出富含Li3N/ lif的固体电解质界面层，可以抑制电解质的连续分解。在Si/Li半电池和LiNi0.8Co0.1Mn0.1O2/Si全电池中，即使在高硅电极负载下，也能取得优异的电化学性能。

期刊介绍： Nano-Micro Letters is a peer-reviewed, international, interdisciplinary and open-access journal that focus on science, experiments, engineering, technologies and applications of nano- or microscale structure and system in physics, chemistry, biology, material science, pharmacy and their expanding interfaces with at least one dimension ranging from a few sub-nanometers to a few hundreds of micrometers. Especially, emphasize the bottom-up approach in the length scale from nano to micro since the key for nanotechnology to reach industrial applications is to assemble, to modify, and to control nanostructure in micro scale. The aim is to provide a publishing platform crossing the boundaries, from nano to micro, and from science to technologies.
