9 Claims

1. A thermoelectric battery comprising a working electrode containing a n-type silicon and germanium, a counter electrode, and a solid electrolyte having a polymer comprising a repeating unit represented by the following formula (1) or a derivative thereof:

wherein R¹is a single bond, an oxygen atom, a sulfur atom, —NH—, —PH₃—, —(P═O)R⁶—, —O—(P═O)H—O—, a carbonate group (—O—(C═O)—O—), a carbonyl group, a sulfonyl group, an ester group, or an arylene dioxy group (—O—Ar—O—),

R², R³, R⁴, and R⁵are independently a hydrogen atom, a fluorine atom, an alkyl group having 1 to 3 carbon atoms, a hydroxyl group, a cyano group, an amino group, a carboxyl group, a phosphoryl group, an aldehyde group, a methylcarbonyl group, a methylsulfonyl group, a sulfanyl group (—SH), a nitro group, a phenoxy group, a methyl ester group, a trifluoromethyl group, and

R⁶is an alkylene group having 1 to 3 carbon atoms,

wherein the repeating unit may be the same, or combinations of two or more repeating units,

wherein a molecular weight of the polymer or the derivative is 200 to 1,000,000, and the solid electrolyte contains copper ions or iron ions as an ion source.
