Abstract
A secondary battery in which convection in an electrolyte solution occurs easily is provided. A secondary battery whose electrolyte solution can be replaced is provided. A nonaqueous secondary battery includes a positive electrode, a negative electrode, a separator, and an electrolyte solution, and the separator includes grooves capable of making convection in the electrolyte solution occur easily. The nonaqueous secondary battery has at least one expected installation direction, and the grooves in the separator are preferably formed so as to be perpendicular to an expected installation surface. The exterior body includes a first opening for injection of an inert gas into the exterior body and a second opening for expelling or injection of an electrolyte solution from or into the exterior body. An electrolyte solution replacement apparatus has a function of injecting the inert gas through the first opening and expelling or injecting the electrolyte solution through the second opening.

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.
