Description
Technical Field
A preparation method of a CuSe nanometer material for a sodium ion battery belongs to the field of sodium ion batteries.
Technical Field
In recent years, with the increasing prominence of the problems of traditional energy sources, the national carbon-neutral-carbon peak policy comes out, and new energy sources such as solar energy, wind energy, tidal energy and the like become hot research directions. The market application of new energy sources is greatly resisted due to the limitation of weather and regions, and the converted electric energy can be stored along with the addition of a chemical power source and then is transmitted to users by using a power grid. Particularly, the appearance of secondary batteries greatly promotes the application of new energy. Although lithium batteries are mainly used at the present stage, the lithium batteries are limited in large-scale energy storage application due to the influence of lithium resource reserves, distribution and price. In contrast, sodium resources are high in storage quantity, uniform in distribution and relatively low in price, sodium and lithium belong to the same group of elements, and the sodium and lithium are similar in property, so that the sodium-lithium composite material is more suitable for large-scale energy storage application. Therefore, the research and development of sodium ion batteries have become one of the directions of hot spot research in the field of secondary batteries.
Development of electrode materials, particularly research on high-performance anode materials, is one of key factors for development and application of sodium ion batteries. The transition metal selenide has been receiving a great deal of attention because of its high theoretical specific capacity, excellent cycle stability, and other properties. Among them, copper selenide has the advantages of higher theoretical specific capacity, high electron conductivity and the like, and is widely reported. The existing literature for preparing the flaky CuSe nano material mainly adopts hydrazine hydrate, sodium borohydride and other explosion-prone dangerous control materials as Se reducing agents or adopts sodium selenite and the like with relatively high price as Se sources. In addition, the existing preparation methods mainly comprise a high-temperature selenizing method, a multi-step liquid phase method, a microwave auxiliary method and the like, the preparation process is complicated, and therefore mixed phases in the product can be possibly caused, in addition, some preparation methods have certain requirements on equipment, so that the cost is high, and the preparation method is not beneficial to actual industrialized scale preparation.
Disclosure of Invention
The invention provides a method with low raw material price, simple preparation process, short period, mild reaction condition and safe and simple operation, and the prepared nano flaky CuSe material has high purity and good electrochemical performance when being used as a negative electrode of a sodium ion battery.
The invention provides a preparation method of a CuSe nano sheet material for a sodium ion battery, which comprises the following steps:
a) Adding deionized water and sodium hydroxide into a 100mL reaction kettle, stirring at room temperature for dissolution, and then adding selenium powder;
b) Stirring at room temperature for 10min, and adding cetyl trimethyl ammonium bromide and copper nitrate trihydrate;
c) Stirring for 10min at room temperature, placing the reaction kettle in a baking oven for hydrothermal synthesis reaction, and carrying out centrifugal water washing and drying treatment;
d) The CuSe nano sheet material is used as an electrode material to be applied to a sodium ion battery.
The addition amounts of deionized water, sodium hydroxide and selenium powder in the step a) are 45.0mL, 208.3mmol and 3.2mmol respectively;
the addition amounts of cetyl trimethyl ammonium bromide and copper nitrate trihydrate in the step b) are 2.1mmol and 2.0mmol respectively;
the temperature of the hydrothermal synthesis reaction in the step c) is 140 ℃, and the reaction time is 1-2.0 h.
In the step d), in the sodium ion battery cycle performance test, the initial specific capacity can reach 425.2mAh/g, the initial coulomb efficiency is 96.9%, and the capacity of the electrode still reaches 335.1mAh/g after 120 cycles.
Compared with other methods for preparing the flaky CuSe, the method has the advantages that the preparation process is greatly simplified, the raw materials which are cheap and easy to obtain are adopted, the preparation conditions are mild and safe, the method is suitable for large-scale production, the production cost is reduced, and the production period is shortened; more importantly, the prepared pure-phase CuSe nano sheet has higher specific capacity and cycle performance when being used for sodium ion batteries.
A Bruker Advance D8X-ray powder diffractometer (Cu ka radiation,2 θ=10 to 80°) the structure of the prepared material was determined. The surface morphology of the prepared material was observed using a Hitachi S-4800 scanning electron microscope. The cell performance was tested using an electrochemical workstation (CHI 660E) and new wire (new) cell test system.
As can be seen from FIG. 1, the prepared CuSe sample had a pure hexagonal structure (JCPDS card No. 34-0171) in which no hetero peaks other than CuSe were detected. As can be seen from FIG. 2, the resulting products were of a sheet-like structure and varied in size. As can be seen from fig. 3, when the CuSe nano-sheet is used as an electrode material of a sodium ion battery for cyclic voltammetry, the cycle curves from the second circle to the fifth circle are basically coincident, which indicates that the nano-sheet has stable electrochemical performance. As can be seen from FIG. 4, the initial sodium storage specific capacity of the CuSe nano sheet can reach 425.2mAh/g, the initial coulomb efficiency is 96.9%, and the capacity is 335.1mAh/g after 120 charge and discharge cycles.
