A High‐Rate and Ultralong‐Life Sodium‐Ion Battery Based on NaTi2(PO4)3 Nanocubes with Synergistic Coating of Carbon and Rutile TiO2

Highly regular NaTi2(PO4)3 nanocubes with synergistic nanocoatings of rutile TiO2 and carbon are prepared as an electrode material for sodium-ion batteries. It exhibits a high rate and ultralong life performance simultaneously, and a capacity retention of 89.3% after 10 000 cycles is achieved.
