Hierarchical polypyrrole-pillared Na 2 V 6 O 16 architectures enabling high-rate and stable aqueous zinc storage
While aqueous Zn-ion batteries represent highly attractive technologies for large-scale grid storage, their practical implementation remains bottlenecked by severe structural degradation and sluggish ion diffusion kinetics in transition-metal oxide cathodes. Herein, a structural buffering hierarchical assembly strategy...
