摘要:
This invention relates to a safe electrolyte having no risk of igniting-firing, and more particularly to a non-aqueous electrolyte for a battery comprising an ionic liquid composed of a cation portion and an anion portion, and a supporting salt, characterized in that the cation portion of the ionic liquid contains phosphorus and nitrogen, as well as an electrolyte for an electric double layer capacitor comprising an ionic liquid composed of a cation portion and an anion portion, characterized in that the cation portion of the ionic liquid contains phosphorus and nitrogen.

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:
In a positive electrode of a non-aqueous electrolyte battery, at least one alkaline earth metal oxide selected from the group consisting of magnesium oxide, calcium oxide and barium oxide is dispersed between particles of an active substance for positive electrode, whereby a discharge capacity or recharge-discharge capacity of the non-aqueous electrolyte battery just after the preparation and after the storing at high temperature is improved.
摘要:
This invention relates to a non-aqueous electrolyte exhibiting a non-combustibility even under a condition having a higher oxygen concentration, and more particularly to a non-aqueous electrolyte characterized by comprising a non-aqueous solvent containing a cyclic phosphazene compound represented by the following general formula (I): (NPR12)n (I) [wherein R1s are independently a halogen element or a monovalent substituent; and n is 3-4] and a fluorophosphate compound represented by the following general formula (II): [wherein R2s are independently a halogen element, an alkoxy group or an aryloxy group, and at least one of the two R2s is the alkoxy group or the aryloxy group], and a support salt.
摘要:
The invention relates to an incombustible separator for a non-aqueous electrolyte cell in which the separator itself does not burn even if the temperature inside the cell becomes high, and more particularly to a separator for a non-aqueous electrolyte cell made of a microporous film formed by a phosphazene derivative and/or an isomer of a phosphazene derivative to a polymer.
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.
