Nonaqueous secondary battery and separator

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.

AI Technical Summary

Benefits of technology

The present invention aims to provide a secondary battery that allows for easy convection of the electrolyte solution, allows for replacement of the electrolyte solution, has high output, long lifetime, and is novel. Additionally, the invention also provides a semiconductor device with low off-state current, low power consumption, high reliability, and a transparent semiconductor layer. The invention also provides a separator that can extend the lifetime of a secondary battery and improve its characteristics.

Problems solved by technology

In addition, it is necessary for the secondary battery to release excessive heat as appropriate because the amount of heat generated by charge-discharge reaction increases as the output increases.
