This invention discloses a method for extracting the intermediate ACH, belonging to the field of fine chemicals. The method involves passing a layered acid containing acesulfame potassium (DCM) and a dichloromethane solution into a rotary extraction tower for extraction. The temperature of the layered acid entering the tower is 30-31°C. The extraction pressure and the temperature of the dichloromethane entering the tower are controlled. The extracted dichloromethane layer enters a vibrating extraction tower for back-extraction with deionized water. The back-extracted DCM is neutralized, concentrated, crystallized, and dried to obtain the finished product, potassium acesulfame potassium. Using this method, the ACH content in the extracted acid is reduced to below 0.1%, and the ACH extraction yield reaches over 98%. Because the rotary extraction tower effectively reduces the acid carryover in the DCM, it lowers the back-extraction load, ensuring the product quality of potassium acesulfame potassium. Simultaneously, it simplifies the process conditions, reduces energy consumption, and saves production costs.

This invention provides an electrolyte and a sodium-ion battery. The electrolyte comprises a sodium salt, a non-aqueous organic solvent, and additives. The additives include: (a) sodium acesulfame potassium, with the structural formula shown in Formula 1; and (b) an acid anhydride compounds. The electrolyte comprises sodium acesulfame potassium and an acid anhydride compounds. Sodium acesulfame potassium can form a tough, shatter-resistant, and high-temperature resistant interfacial film during the first charge-discharge stage of the battery. However, this interfacial film contains sulfur and nitrogen elements, which easily dissolve in the electrolyte, consuming some of the active sodium to form a new interfacial film, causing gas production and a decrease in the initial coulombic efficiency of the battery. The acid anhydride compounds, due to their high film-forming potential, easily form a dense interfacial film at the negative electrode, effectively mitigating the side reactions of sodium acesulfame potassium in the electrolyte after film formation. Using this electrolyte in a sodium-ion battery can improve the initial coulombic efficiency, high-temperature storage performance, and cycle performance of the sodium-ion battery under high voltage.
