Robust LiTi2(PO4)3 Microflowers As High-rate and Long-life Cathodes for Mg-based Hybrid Ion Batteries

Abstract

A novel NASICON-type carbon-coated LiTi2(PO4)3 microflowers (LTP-F/C) as hybrid magnesium−lithium-ion batteries (MLIBs) cathode is presented for the first time. Benefiting from the synergistic effect of NASICON structure, nanosheet-constructed hierarchical architecture, and uniform carbon coating of LTP-F/C, this hybrid MLIB exhibits extraordinary electrochemical performance: ultra-high cycling stability (capacity retention of 80% after 3000 cycles at 10 C) and outstanding rate capability (94 mA h g-1 at 20 C) under a high discharge voltage plateau of ~1.71 V (vs Mg/Mg2+). This hybrid battery system design is highly promising for large-scale energy storage applications.
