摘要
采用溶剂热法合成了铌钼氧化物纳米颗粒Nb14Mo3O44，并对其作为锂离子电池的新型阳极进行了探索。Nb14Mo3O44属于由moo4四面体连接的4×4×∞nbo6八面体块组成的四方结构，为Li + de/插层提供了稳定的结构。nb14mo3o44纳米颗粒具有较高的比表面积和反应活性，其初始库仑效率(90.6%)、循环性能(503次循环后为218 mAh g -1)和速率性能(20 C时为74 mAh g -1)均优于固相反应得到的团聚微粒。
Nb 14Mo 3O 44 Nanoparticles Fabricated by a Facile Solvothermal Method as Novel Anode for Lithium-Ion Batteries
The niobium molybdenum oxide Nb14Mo3O44 nanoparticles are synthesized by a convenient solvothermal method and explored as new anodes for lithium-ion batteries.Nb14Mo3O44 , which belongs to tetragonal structure that consists of 4×4×∞ NbO 6 octahedra-blocks linked by MoO 4 tetrahedra, generates stable structure for the efficient Li + de/intercalation. Compared with the agglomerated microparticles obtained by solid-state reaction, Nb14Mo3O44nanoparticles demonstrate a higher initial coulombic efficiency ( 90.6 %), better cycle property (218 mAh g -1 after 503 cycles at 0.5 C) and improved rate capability (74 mAh g -1 at 20 C), benefiting from nanoparticles possessed rather high specific surface area and reaction reactivity.
