Petal‐like rutile TiO 2 wrapped by ultrathin graphene‐rich layers are proposed by X. Ji and co‐workers on page 9391 as superior anodes for sodium‐ion batteries featuring outstanding high‐rate capabilities and remarkable long‐term cycle life, benefiting from promoted electron transport and shortened Na + diffusion length. This is of great significance to improve the energy and power density for its application to electric vehicles (EVs) and energy‐storage systems (ESSs).
