Hierarchical Ni3V2O8@N‐Doped Carbon Hollow Double‐Shell Microspheres for High‐Performance Lithium‐Ion Storage

Transition metal oxides (TMOs) are highly dense in energy and considered as promising anode materials for a new generation of alkaline ion batteries. However, their electrode structure is disrupted due to significant volume changes during charging and discharging, resulting in the short cycle life of batteries. In this paper, the hierarchical Ni
