An electrolyte solution for a secondary lithium battery, the electrolyte solution including: a lithium salt, a non-aqueous organic solvent, and a phenanthroline-based compound having a polar substituent. The electrolyte solution enables production of a secondary lithium battery having a good high-temperature lifetime characteristics and good high-temperature preservation characteristics.

Electrode active material for power storage device, and power storage device

The present invention provides an electrode active material for an electricity storage device, having a structure represented by following formula (1). In the formula (1), Rto Reach denote independently a hydrogen atom (except for a case where all of Rto Rdenote hydrogen atoms), a halogen atom, an optionally substituted phenyl group, an optionally substituted heterocyclic group, or an optionally substituted hydrocarbon group having 1 to 4 carbon atoms.

Electrode active material for electricity storage device, and electricity storage device using same

An electrode active material for a power storage device of the invention includes a ketone compound that includes a ring structure in a molecule, the ring structure being a five-membered or seven-membered ring composed of atoms at least three adjacent ones of which are each bonded to a ketone group. The electrode active material for a power storage device of the invention has a high weight-energy density and good reversibility of oxidation-reduction reaction. The use of the electrode active material for a power storage device of the invention can provide a power storage device having a high capacity, a high voltage, and good charge/discharge cycle characteristics.

Electrode active material for power storage device, power storage device, and electronic and transport devices

Disclosed is a novel organic compound synthesized by oligomerizing or polymerizing a specific quinone compound having two quinone groups at the ortho position and having a property such that the electron transfer occurs associated with a reversible redox reaction, the organic compound being insoluble in an organic solvent and having a high energy density, and thus being useful as an electrode active material for a power storage device. Using this organic compound as an electrode active material can improve the energy density, reduce the weight and size, and improve the functionality of the power storage device.

Phenanthrenequinone compound, electrode active material, and power storage device
