Suppressing Fe–Li Antisite Defects in LiFePO₄/Carbon Hybrid Microtube to Enhance the Lithium Ion Storage

Abstract

LiFePO4/carbon hybrid microtubes (LFP/CMT) are synthesized through the use of the strong chelation interaction with Fe3+ and absorb interaction with Li+ of alginate. This approach yields LFP/CMT with the lowest Fe–Li antisite defects, which exhibits remarkable capacity, rate ability, and long-term cycling stability for Li ion batteries.
