Abstract

An organic solid electrolyte is disclosed, which comprises a high molecular compound having a recurring unit represented by following formula (I), a nonprotonic polar solvent, and a salt of a metal ion belonging to group Ia or group IIa of the Periodic Table: ##STR1## wherein R₁ represents a hydrogen atom, a lower alkyl group, a cyano group, or a chlorine atom; R₂ represents a lower alkyl group, an alkenyl group, an aryl group, or an aralkyl group; X represents --CO₂ --, ##STR2## --OCO--, or --O--, (wherein R₃ represents a hydrogen atom or a lower alkyl group); L represents an alkylene group; a represents 0 or 1; and m represents an integer of from 0 to 5.

Claims

1. An organic solid electrolyte comprising a high molecular compound having a recurring unit represented by following formula (I), a nonprotonic polar solvent, and a salt of a metal ion belonging to group Ia or group IIa of the Periodic Table:

##STR28## wherein R₁ represents a hydrogen atom, a lower alkyl group, a cyano group, or a chlorine atom;

R₂ represents a lower alkyl group, an alkenyl group, an aryl group, or an aralkyl group;

X represents --CO₂ --, ##STR29## --OCO--, or --O--, (wherein R₃ represents a hydrogen atom or a lower alkyl group);

L represents an alkylene group;

a represents 0 or 1; and

m represents an integer of from 0 to 5.

2. The organic solid electrolyte of claim 1, wherein the organic solid electrolyte is formed in a thin film form.

5. The organic solid electrolyte of claim 2 or 4, wherein the thin film is formed by a heating method.

6. The organic solid electrolyte of claim 1 or 3, wherein the organic solid electrolyte is filled in a porous film having a mean pore size of at least 0.15 μ

m to form a thin film.

7. The organic solid electrolyte of claim 6, wherein the porous film is composed of polyolefin.

8. The organic solid electrolyte of claim 6 or 7, wherein the thin film is formed by a heating method.

3. An organic solid electrolyte comprising a high molecular matrix composed of a monomer represented by the following formula (II) and a monomer represented by the following formula (III), a nonprotonic polar solvent, and a salt of a metal ion belonging to group Ia or group IIa of the Periodic Table:

##STR30## wherein R₁ represents a hydrogen atom, a lower alkyl group, a cyano group, or a chlorine atom;

R₂ represents a lower alkyl group, an alkenyl group, an aryl, group, or an aralkyl group;

X represents --CO₂ --, ##STR31## --OCO--, or --O-- (wherein R₃ represents a hydrogen atom or a lower alkyl group);

L represents an alkylene group;

a represents 0 or 1; and

m represents an integer of from 0 to 5;

##STR32## wherein Y represents an l-valent atomic group composed of carbon or carbon and hydrogen;

a'"'"' represents 0 or 1;

l represents an integer of at least 2; and
