Abstract
A polymer solid electrolyte for an electrochemical device including a magnesium electrode as a negative electrode, the polymer solid electrolyte including a Mg polymer salt containing Mg2+ and an anionic polymer having an anionic functional group and a coordinating functional group, and the polymer solid electrolyte having Mg ion conductivity.
Claims3
A method for producing a polymer solid electrolyte having Mg ion conductivity, the method comprising
- dissolving a Li polymer salt represented by general formula (4):
- in the general formula (4), Af represents an anionic functional group, T represents a terminal group, m represents an integer of 3 to 40, n represents an integer of 150 to 850, p and q each represent an integer of 1 to 10, and p and q may be same or different from each other, in a linear ether solution of a Mg salts;
- and adding a linear ether to precipitate a Mg polymer salt represented by general formula (5):
- in the general formula (5), Af represents an anionic functional group, T represents a terminal group, m represents an integer of 3 to 40, n represents an integer of 150 to 850, p and q each represent an integer of 1 to 10, and p and q may be same or different from each other.
