Porous FeO x /carbon nanocomposites with different iron oxidation degree for building high-performance lithium ion batteries

Abstract: Transition metal oxides have attracted lots of interest for lithium ion battery (LIB) due to the high theoretical capacity, however, the large specific volume change, low electrical conductivity and slow intrinsic lithiation/delithiation still limit the practical applications. In order to overcome the challenge, a novel type of high temperature annealing treatment for the synthesis of 3D porous FeOx nanocrystals embedded in a partially carbon matrix as an example for high-performance LIB is reported. The FeOx/… Show more

“…have been proposed to be an excellent potential replacement for graphite due to high theoretical capacity (2-3 times of graphite) and moderate electronic conductivity (higher than Si). [13][14][15][16][17] However, the high average delithiation potential (higher than 1 V vs. Li/Li þ ) of transition metal compounds reduces the gravimetric energy density in the full cell. Most recently, phosphorus-based anode materials have drawn much attention for their capability for fast charging.…”

“…The development of sustainable energy storage system becomes supreme by reason of the continuously increasing demand for energy consumption [1][2][3][4][5][6]. Lithium-ion batteries [7][8][9], which are widely used in portable electronic devices [10], have attracted much attention. However, it could hardly meet the needs of high energy density and specific capacity due to relatively heavy host structures and state of charge limitations for cathode material [11,12].…”
