Oxygen-Vacancy-Rich Na1.3Ti1.8Ni0.1Sb0.1(PO4)3@C Anode for High-Rate and Low-Temperature Sodium-Ion Storage.
NASICON-type NaTi2(PO4)3 as an electrode material for sodium-ion batteries has attracted considerable attention due to its high structural stability and safety, yet its low intrinsic electronic conductivity limits high-rate and low-temperature performance. In this work, an oxygen-vacancy-rich Na1.3Ti1.8Ni0.1Sb0.1(PO4)3...
