Abstract

The invention discloses an inorganic nonmetal sodium ion battery cathode material and a preparation method thereof, and particularly relates to the technical field of sodium battery cathode material.The inorganic nonmetal sodium ion battery cathode material comprises 10-20 parts of sodium carbonate, 5-16 parts of sodium acetate, 8-23 parts of sodium nitrate. 5-15 parts of sodium hydroxide, 5-16 parts of manganese carbonate, 8-16 parts of manganese acetate, 10-25 parts of manganese nitrate, 10-18 parts of manganese oxide, and 15-20 parts of ammonium molybdate. The cathode material prepared bymixing a solution obtained by mixing and stirring ammonium dihydrogen phosphate, ammonium phosphate, diammonium hydrogen phosphate and phosphoric acid and a solution obtained by dissolving ammonium molybdate and molybdenum oxide in an aqueous solvent improves the stability of the sodium battery during a charge-discharge process, and it can be obviously discovered that the conductivity and the charging efficiency are significantly improved and in a long-term test, the discharge specific capacity is still not significantly attenuated, thereby ensuring the stability of the sodium battery made ofthe cathode material in use.

Description

technical field [0001] The invention relates to the technical field of anode materials for sodium batteries, more specifically, the invention relates to an anode material for an inorganic non-metallic sodium ion battery and a preparation method thereof. Background technique [0002] Sodium-ion battery is a secondary battery (rechargeable battery), which mainly relies on sodium ions to move between the positive and negative electrodes. It works similarly to the working principle of lithium-ion batteries. The electrode materials used in sodium-ion batteries It is mainly sodium salt, which is more abundant and cheaper than lithium salt. Since sodium ions are larger than lithium ions, sodium-ion batteries are a cost-effective alternative when weight and energy density are not critical. [0003] Compared with lithium-ion batteries, sodium-ion batteries have the following advantages: rich reserves of sodium salt raw materials, low prices, the use of iron-manganese-nickel-based po...
