ELECTRODE ACTIVE MATERIAL FOR ELECTRIC STORAGE DEVICE, ELECTRIC STORAGE DEVICE, ELECTRONIC EQUIPMENT, AND TRANSPORTATION EQUIPMENT

摘要

Disclosed is an electrode active material for an electric storage device, comprising an organic compound having a plurality of electrode reaction sites and a linker site in a molecule thereof. The electrode reaction sites are a residue of a 9,10-phenanthrenequinone compound that contributes to an electrochemical redox reaction. The linker site is provided between the plurality of electrode reaction sites, is free from a ketone group, and does not contribute to an electrochemical redox reaction. The electrode active material for an electric storage device has a suppressed solubility in an electrolyte and has a high energy density. The use of the electrode active material can provide an electric storage device having a high energy density and excellent charge-discharge cycle characteristics.
