"Synergistic nanostructure and heterointerface design propelled ultra-e" by Hao Luo, Bo Wang et al.
In-situ self-transformation is proved to be an effective strategy to design high-performance cathodes for aqueous zinc-ion batteries (ZIBs). However, the inferior transformation efficiencies during phase transition limit its further application. Herein, a 3D spongy VO -graphene (VO -rG) precursor has been designed for achieving the ultra-efficient in-situ self-transformation process from VO -rG into multifaceted V O ·nH O-graphene composite (VOH-rG). Benefiting from the highly conductive heterointerfaces, rich reaction sites and numerous ions diffusion channels of VO -rG, almost 100% VO nano...
