Abstract
A non-aqueous electrolyte battery which exhibits satisfactory reliability because reduction in the discharge capacity can be significantly prevented even after use with rapid temperature change and which enables excellent productivity to be realized. The non-aqueous electrolyte battery includes a cathode and an anode in which an active material for the cathode and/or an active material for the anode is integrated by a binder, wherein the binder for the cathode and/or the binder for the anode is a mixture of polyimide, which is soluble in an organic solvent, and a fluorine polymer. The polyimide is expressed by the following formula: ##STR1##

Important Notes on Latency of Status data
Please note there is up to 60 days of latency in this Status indicator for certain status conditions. You can obtain up-to-date Status indicator readings by ordering PAIR for the file.
An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.
A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.
An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
Important Note on Priority Date data
This priority date is an estimated earliest priority date and is purely an estimation. This date should not be taken as legal conclusion. No representations are made as to the accuracy of the date listed. Please consult a legal professional before relying on this date.
