Abstract
Disclosed are an electrode active material for a power storage device and a power storage device including the same. The electrode active material includes a polymer that includes: a tetravalent group derived from a compound selected from the group consisting of EBDT and derivatives thereof, TTF and derivatives thereof, a condensation product of EBDT and TTF and derivatives thereof, and a TTF dimer and derivatives thereof; and a divalent group —S-A-S— where A is a divalent aliphatic group or a divalent group represented by the formula -E-D-E- where D represents a divalent alicyclic group, a divalent aromatic group, or a carbonyl group, and two Es each independently represent a divalent aliphatic group. Adjacent two tetravalent groups mentioned above are linked by one or two divalent groups mentioned above.
