چکیده انگلیسی
KTiOPO4 (KTP) microblocks, which were prepared using a simple solid state method, have been used as novel anode materials for sodium ion batteries (SIBs). The as-prepared KTP microblocks with size distribution of 300-500â¯nm delivered high performance of electrochemical storage of sodium, such as an initial charge capacity of 108.7â¯mAh gâ1 at 200â¯mAâ¯gâ1 with almost no capacity loss in 1000 cycles, and good rate capability of 80.3â¯mAh gâ1 even at the current density of 1000â¯mAâ¯gâ1. Ex situ XPS and in situ XRD showed an irreversible phase reaction mechanism during the insertion/extraction of Na+. Dendrite formation at lower potential could be suppressed at the average potential of 1.3â¯V. This work indicated that KTP microblocks are low-cost and safe anode materials for SIBs.
