Abstract A novel ternary transition metal oxide (TTMO) FeMnO3 microcube with an average diameter of about 1.0 μm was successfully fabricated via the pyrolysis of Mn-Fe Prussian blue analogue (PBA) at 650 °C. As an anode material for lithium ion batteries (LIBs), it showed a steady reversible capacity of 710 mAh g−1 at a high current density of 1 A g−1 after 200 cycles with 80% retention. The remarkable electrochemical storage properties are attributed to the microcubic structure inherited from the precursor and structure stability, which can effectively buffer the volume expansion during the discharge-charge process. Its excellent features, such as low cost, environmentally friendliness, simple preparation and outstanding electrochemical properties, make the obtained FeMnO3 a promising electrode material for electrochemical storage devices.

源自普鲁士蓝类似物的三元过渡金属氧化物用于高性能锂离子电池

摘要 通过Mn-Fe 普鲁士蓝类似物(PBA) 在650 °C 下热解,成功制备了平均直径约1.0 μm 的新型三元过渡金属氧化物(TTMO) FeMnO3 微立方体。作为锂离子电池 (LIBs) 的负极材料,它在 1 A g-1 的高电流密度下在 200 次循环后显示出 710 mAh g-1 的稳定可逆容量,并具有 80% 的保留率。显着的电化学存储性能归因于前驱体继承的微立方结构和结构稳定性,可以有效缓冲充放电过程中的体积膨胀。FeMnO3 具有成本低、环境友好、制备简单和电化学性能优异等优异特性,使其成为一种很有前途的电化学存储器件电极材料。
