A novel method for preparing α-LiFeO2 nanorods for high-performance lithium-ion batteries

Abstract

One-dimensional (1D) α-LiFeO 2 nanorods are successfully prepared via a low-temperature solid-state reaction from α-FeOOH nanorods synthesized by hydrothermal process and used as cathode materials in lithium-ion batteries. As cathode material for lithium-ion batteries, the nanorods can achieve a high initial specific capacity of 165.85 mAh/g at 0.1 C for which a high capacity retention of 81.65% can still be obtained after 50 cycles. The excellent performance and cycling stability are attributed to the unique 1D nanostructure, which facilitates the rapid electron exchange and fast lithium-ion diffusion between electrolyte and cathode materials.

Study of alternative current conduction mechanisms on the -LiFeO 2 - Based solid electrolyte

“…Although the conductivity of LiFeO2 composite is lower than that of commercial LiCoO2, this composite remains a good non-toxic candidate in Li battery applications which achieved a constant specific capacity of 139.8 mAhg −1 at 0.1C after 50 cycles under the effect of improvement in shape [42].…”

“…Layered lithium and transition metal oxides LiMO2 (M = Co, Mn, Ni, Fe…) considered among the most promising cathode materials for Li-ion batteries (NIBs) due to their large capacity, high energy density, good electrochemical stability and long cycle life [1][2][3][4][5]. The most marketable electrode is that based on cobalt, although it is toxic, thanks to its easy production, its high specific capacity (274mAh/g) and good cycling stability [4,5].LiFeO2 is the least toxic compound characterized by high electrochemical performance due to its high theoretical capacity (282 mAh/g) and its low cost [6,7].…”
