Abstract

A three-dimensional all-in-one Sn-Co alloy anode is reported for the first time, which delivers a high capacity along with a stable coulombic efficiency as well as good temperature tolerance. The binder-free electrode eliminates the complexity of conventional slurry preparation while maintaining an integrated scaffold, which provides space to accommodate volume expansion, as confirmed by an in situ transmission electron microscopy study.
