Phase transition of hollow-porous α-Fe2O3 microsphere based anodes for lithium ion batteries during high rate cycling

In the present paper, hollow-porous α-Fe2O3 microspheres are prepared via cation etching of zinc citrate microspheres and subsequent thermal treatment. The superior performance of the as-obtained α-Fe2O3 microspheres as an anode material for lithium ion batteries is evaluated. After 1000 cycles, the capacity still remains more than 1100 mA h g-1 at a current rate of 1 A g-1. Meanwhile, the crystal size induced phase transition of Fe2O3 microspheres (α → γ → β) is observed during cycling by the measurements of ex situ XRD and TEM, which is responsible for their abnormal performance fluctuation.

MAGNESIUM CITRATE GLYCINATE CO-SALT

A magnesium citrate glycinate co-salt has a formula of Mg2C8H9NO9 - X H2O and a suggested structure of Formula I. The magnesium citrate glycinate co-salt has an apparent density of 1740 kg/m3 and is compressible in a range of compression pressures from approximately 50 MPa to approximately 150 MPa. The magnesium citrate glycinate co-salt is formed by combining citric acid and glycine in a 1:1 molar ratio to form an aqueous reaction mixture and neutralizing the aqueous reaction mixture with a magnesium source having a magnesium:ligand ratio of 1:1.

A zinc citrate trihydrate synthetic method

The invention relates to a method for synthesizing zinc citrate trihydrate. The method comprises the following steps: adding citric acid and deionized water into a reaction kettle, and stirring and heating to the temperature of 55-65 DEG C; adding a zinc compound, adding a catalyst and aids after the zinc compound is completely added, stirring, heating, and reacting; centrifuging and filtering after the reaction is ended, sequentially washing and performing absolute ethyl alcohol washing on the obtained solids; and finally, fully performing vacuum drying, thereby obtaining the zinc citrate trihydrate. According to the method, a complex reaction system with specific catalyst and aids is adopted, rapid and high-yield preparation of the target product is realized by virtue of dual effects of the micro-hole reaction environment and assistant catalysis, and the method has very obvious technical effects and achieves wide industrial application prospects and market potentials.
