文摘

Petal-like rutile TiO₂ 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).
