非水電解質電池
Document Type and Number:
Japanese Patent JP4359942
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To improve charge/discharge performances in a high temperature, a shelf performance and safety in an abnormally-high temperature, by including polycyclic alicyclic hydrocarbons or derivatives thereof in an electrolyte a polymer gel electrolyte or a polymer solid electrolyte. SOLUTION: Polycyclic alicyclic hydrocarbons to be included are, preferably, pinene, canphene, bicyclo-octene, bicyclo-octane, bornene, fenchene, or ester/ether compounds having these skeletons. Especially, pinene or canphene in a mono- terpene group or its derivatives such as Nopylacetate or the like are preferable. These compounds trap radicals, which are produced in a high temperature and may become a cause of decomposition deterioration of an electrolyte or spontaneous ignition, and change them into inactive forms. These compounds are used as a solvent component of an electrolysis solution or a polymer gel electrolyte, or a plasticizer component of a polymer solid electrolyte, and a sub-solvent is also used. Also, polymer material forming a polymer gel electrolyte or a solid electrolyte may contain these compounds as its component.
