Abstract
It is an object of the present invention to provide an electrolytic solution having high oxidation decomposition potential, where dissolution and deposition of magnesium proceed repeatedly and stably, using a non-nucleophilic alkoxide-type magnesium salt. The present invention relates to (1) an electrolytic solution for a magnesium battery comprising a mixture of a compound represented by the following general formula (I), a Lewis acid and a solvent: (2) an electrochemical device comprising the electrolytic solution, a positive electrode and a negative electrode, and (3) a compound represented by the following general formula (I′):
Claims11
An electrolytic solution for a magnesium battery comprising a mixture of a compound represented by the following general formula (I), a Lewis acid and a solvent:
- wherein Y represents a carbon atom or a silicon atom, X represents a chlorine atom or a bromine atom, R1 represents an aryl group having 6 to 10 carbon atoms, which may have a halogeno group, an alkyl group, a halogenoalkyl group or an alkoxy group, as a substituent, R2 and R3 each independently represent a magnesium chloride oxy group (—OMgCl);
- a magnesium bromide oxy group (—OMgBr);
- an alkenyl group having 1 to 6 carbon atoms;
- an alkyl group having 1 to 6 carbon atoms, which may have a halogeno group or an alkoxy group, as a substituent;
- or an aryl group having 6 to 10 carbon atoms, which may have a halogeno group, an alkyl group, a halogenoalkyl group or an alkoxy group, as a substituent.
A compound represented by the following general formula (I′):
- wherein X represents a chlorine atom, R′1 represents an aryl group having 6 to 10 carbon atoms, which may have a halogeno group, an alkyl group, a halogenoalkyl group or an alkoxy group, as a substituent, R′2 and R′3 each independently represent a magnesium chloride oxy group (—OMgCl);
- a magnesium bromide oxy group (—OMgBr);
- an alkenyl group having 1 to 6 carbon atoms;
- an alkyl group having 1 to 6 carbon atoms, which may have a halogeno group or an alkoxy group;
- or an aryl group having 6 to 10 carbon atoms, which may have a halogeno group, an alkyl group, a halogenoalkyl group or an alkoxy group, as a substituent.
