The invention relates to an electrolytic capacitor having a flame retardant electrolyte and a high safety even if the electrolyte leaks out to outside, and more particularly to an electrolytic capacitor comprising a positive electrode provided with an insulating oxide layer formed through anodic oxidation, a negative electrode, a separator and an electrolyte containing a solute in an organic solvent, characterized in that the electrolyte contains not less than 3% by mass of a phosphazene derivative and/or an isomer of a phosphazene derivative.
摘要:
In a positive electrode of a non-aqueous electrolyte battery, at least one metal oxide selected from the group consisting of titanium dioxide, alumina, zinc oxide, chromium oxide, lithium oxide, nickel oxide, copper oxide and iron oxide is dispersed between particles of an active substance for the positive electrode, whereby a discharge capacity or a discharge-recharge capacity of the non-aqueous electrolyte battery is improved.

摘要:
A support salt for a cell comprising a compound represented by the following formula (I) or (II): (NPA12)3 (I) A13P═N—P(═O)A12 (II) (in the formulae (I) and (II), A1 is independently NRLi or F, and at least one of A1s is NRLi, and R is a monovalent substituent) has an effect of suppressing combustion, and a non-aqueous electrolyte cell and a polymer cell using such a support salt considerably reduce the risk of ignition-fire and are high in the safety.
