In Situ Synthesis of the Peapod-Like Cu–SnO2@Copper Foam as Anode with Excellent Cycle Stability and High Area Specific Capacity (Adv. Funct. Mater. 33/2021)

Cu-SnO2@Copper Foam In article number 2101999, Wenbo Liu and co-workers design and construct a unique peapod-like Cu-SnO2@ copper foam based on the Kirkendall effect, which can directly act as a binder-free integrated anode for lithium-ion batteries and exhibits excellent Li storage performance primarily because Cu nanoparticles like peas dispersing in the hollow SnO2 “pod” form a connected internal conductive network, greatly promoting electron migration inside electrode.
