非水電解液添加剤、非水電解液二次電池及び非水電解液電気二重層キャパシタ
Document Type and Number:
Japanese Patent JP5001507
Kind Code:
B2
Abstract:
The present invention provides an additive which is able to make a non-aqueous-electrolyte secondary cell or a non-aqueous electrolyte electric double layer capacitor which is excellent in low-temperature characteristics, while maintaining a necessary cell properties, and a non-aqueous-electrolyte secondary cell or a non-aqueous electrolyte electric double layer capacitor that contains therein the additive. The additive contains at least one of tautomers of phosphazene derivatives represented by formulae (1) and (2): wherein R<1>, R<2> and R<3> independently represent a monovalent substituent or a halogen element; X represents a substituent containing at least one selected from a group of carbon, silicon, germanium, tin, nitrogen, phosphorus, arsenic, antimony, bismuth, oxygen, sulfur, selenium, tellurium and polonium; and Y<1> and Y<2> independently represent a divalent connecting group, a divalent element or a single bond.
