설명

일반 설명

Anhydrous sodium perchlorate is a white crystalline solid. It is hygroscopic and absorbs water to form its monohydrate. Anhydrous sodium perchlorate is highly soluble in water, and soluble in a range of polar organic solvents such as methanol, ethanol, acetone, carbonates (including ethylene carbonate, dimethyl carbonate, propylene carbonate, and diethyl carbonate), and ethers (including dimethoxyethane, tetrahydrofuran, and triethylene glycol dimethyl ether). It is insoluble in benzene, chloroform, and toluene.

애플리케이션

The major application of anhydrous sodium perchlorate is as an electrolyte in sodium-ion batteries. It is popular because of its solubility in ethers and carbonates, its wide electrochemical stability window (e.g. from 0 to 5 V vs Na+/Na in propylene carbonate, triglyme, or diethylcarbonate)[1], and its compatibility with a wide range of materials. It has been used in batteries with hard-carbon anodes[2], mesoporous carbon anodes[3], sodium cobalt oxide cathodes (Na_xCoO₂)[4], sodium vanadium oxide cathodes (Na_xVO₂)[5], titanium dioxide cathodes[6], and emerging materials like high-entropy layered oxide cathodes[7].
