Hydrothermal synthesis method for producing Nano sheet material of stannous oxide

Abstract

This invention discloses a hydrothermal method for synthesizing stannous oxide nanomaterial. The method comprises: (1) dissolving stannous chloride in citric acid or polyethylene glycol, controlling the mol concentration of stannous chloride, and stirring; (2) adding 4-10 mol times of hydrazine hydrate, and continuing stirring; (3) filling 80-90% of a pressure kettle with the solution, and treating at 120-150 deg.C for 10-24 h; (4) centrifuging the treated solution, and drying to obtain stannous oxide sheets. Hydrazine hydrate is adopted, by replacing sodium hydroxide or ammonia solution, as an alkali mineralizing agent. Meanwhile, the metastable stannous oxide product cannot be oxidized due to the reducibility of hydrazine hydrate.

technical field

[0001] The invention relates to a hydrothermal synthesis method of stannous oxide nano sheet. Background technique

[0002] With the intensification of energy crisis and environmental damage, new energy and renewable clean energy technologies have attracted great attention from the global research community and business circles, including rechargeable battery technology represented by lithium-ion secondary batteries. Lithium-ion batteries, as a new generation of rechargeable batteries, have developed rapidly in the past 10 years, and have dominated the field of mobile electronic terminal equipment such as notebook computers and mobile phones, with broad market prospects.

[0003] Lithium-ion batteries are generally composed of basic elements such as positive electrode, negative electrode, separator and electrolyte. The negative electrode material is one of the key technologies of lithium-ion batteries. The negative electrode materials currently used can be di...
