Definitions
- the invention belongs to the technical field of sodium ion batteries, and in particular relates to a preparation method of a P2 type manganese-based sodium ion battery cathode material.
- Lithium-ion batteries have been widely used in portable electronic devices, electric vehicles and other fields, and have achieved great success and a very rapid growth momentum.
- the low reserves of lithium resources lead to rising costs of lithium-ion batteries, and sodium-ion batteries are expected to replace lithium-ion batteries in large-scale energy storage devices.
- layered transition metal oxides, especially sodium-manganese oxides have attracted extensive attention due to their advantages such as high specific capacity and working voltage, easy preparation, environmental friendliness, non-toxicity, and low cost.
- Layered sodium manganese oxide is one of the positive electrode materials for sodium ion batteries, which is mainly divided into two structures: P2 phase and O3 phase. Compared with the O3 phase structure, the P2 phase structure has higher ionic conductivity and lower diffusion barrier. Therefore, P2-type manganese-based layered oxides are a very potential cathode material for sodium-ion batteries.
- the electrochemical performance of P2-Na 0.67 MnO 2 material is excellent, the theoretical specific capacity is about 173mAh/g, and the average working voltage is as high as 3.8V, which has attracted extensive attention of researchers in related fields.
- the synthesis process of P2-Na 0.67 MnO 2 material is simple. Compared with most P2 phase materials, after sintering, high-temperature quenching is not required to ensure that the material does not undergo P2-P3 phase transformation. After sintering, natural cooling can obtain the P2 structure. It is conducive to the wide application of materials. The P2-Na 0.67 MnO 2 material will undergo P2-O2 transition when charged above 4.2V.
- Element doping is an effective means to reduce the ordering degree of Na + vacancies, improve the diffusion ability of Na +, improve the rate performance of materials, inhibit phase transition and improve cycle stability.
- Doping and modifying the material can improve the lattice structure of the electrode material, improve the thermal stability of the material, increase the ion diffusion capacity of the material, and reduce the capacity loss during cycling, thereby enhancing the overall electrochemical performance of the sodium-ion battery.
- the currently reported doping modification technology is generally solid-state sintering of manganese source, sodium source and doping elements together, which makes it difficult for doping elements to enter the NaMnO 2 crystal structure or the amount of doping elements entering the structure is small, making it difficult to To achieve the ideal function of stabilizing the crystal structure.
- Li + ion radius is smaller than the Na + ion radius
- Li + is more likely to enter the material lattice during the one-step high-temperature solid-state synthesis process, while Na + is difficult to obtain due to its larger ion radius. It completely enters the interior of the lattice, leaving a large amount of sodium compounds on the surface of the material, which affects the electrochemical performance of the material.
- the present invention aims to solve at least one of the technical problems in the above-mentioned prior art. For this reason, the present invention proposes a method for preparing a P2-type manganese-based sodium-ion battery cathode material, which can improve the doping effect of doped metals and the intercalation of sodium ions, thereby improving the stability and electrochemical performance of the material.
- a kind of preparation method of P2 type manganese-based sodium ion battery cathode material comprising the following steps:
- step S1 the concentration of the oxalic acid solution is 2-5mol/L; the solid-liquid ratio of the manganese dioxide addition to the oxalic acid solution is (25-80) g : 1L.
- step S1 the temperature of the reaction is 70-90°C.
- the concentration of the sodium hydroxide solution is 0.5-2.0 mol/L.
- the doping metal is at least one of copper, nickel or magnesium.
- the alcohol solution containing doping metal is an alcohol solution of at least one of copper chloride, nickel chloride, magnesium chloride or magnesium bromide.
- the alcohol in the alcohol solution is ethanol.
- step S3 the concentration of the doping metal in the alcohol solution containing the doping metal is 0.05-0.35mol/L, and the amount of the alcohol solution containing the doping metal is the 0.8-1.2 times the volume of the oxalic acid solution.
- washing the precipitate is also included after the solid-liquid separation.
- both solid-liquid separation and washing operations are completed under light-shielding conditions, and absolute ethanol is used for the washing.
- the manganese source is at least one of manganese dioxide, manganese oxalate, manganese acetate or manganese carbonate.
- step S4 in the mixed material, the molar ratio of sodium to manganese is (1-3):3.
- step S4 the temperature of the calcination is 800-1000°C.
- step S4 the calcination time is 10-24h.
- the present invention adopts the complexation reaction of oxalic acid and manganese dioxide, and after being neutralized by sodium hydroxide, sodium trioxalate manganate is obtained.
- the precipitate containing sodium trioxalate manganate is used as the sodium source.
- doped metals further stabilizes its internal structure, overcomes the problems of uneven doping of elements and easy collapse of the lattice during solid-phase sintering in the prior art, and further improves the specific capacity and cycle performance of the cathode material of sodium-ion batteries and rate performance.
- FIG. 1 is an SEM image of a P2 type manganese-based sodium ion battery positive electrode material prepared in Example 1 of the present invention.
- step (3) Add 2.0mol/L sodium hydroxide solution immediately after the reaction in step (2), until the pH of the solution is 4.8-5.2, after the reaction, obtain the second reaction solution, which is carried out in an ice bath;
- step (3) Add 1.0mol/L sodium hydroxide solution immediately after the reaction in step (2), until the pH of the solution is 4.8-5.2, after the reaction, obtain the second reaction solution, which is carried out in an ice bath;
- Preparation concentration is 100mL of nickel chloride ethanol solution of 0.07mol/L, and joins in the second reaction liquid of step (3) ice bath and carries out alcohol analysis, and ethanol is dehydrated alcohol;
- step (3) Add 2.0mol/L sodium hydroxide solution immediately after the reaction in step (2), until the pH of the solution is 4.8-5.2, after the reaction, obtain the second reaction solution, which is carried out in an ice bath;
- Preparation concentration is 80mL of copper chloride ethanol solution of 0.35mol/L, and joins in the second reaction liquid of step (3) ice bath and carries out alcohol analysis, and ethanol is dehydrated alcohol;
- a P2-type manganese-based sodium-ion battery positive electrode material is prepared.
- the difference from Example 2 is that the sodium source and the manganese source are directly sintered in solid phase without doping.
- the specific process is as follows:
- Manganese oxalate and sodium oxalate are mixed according to the elemental molar ratio of sodium to manganese of 2:3, ground, and calcined at 900°C for 18 hours to obtain a manganese-based sodium-ion battery cathode material.
