Abstract

An insulating plate of a nonaqueous electrolyte secondary cell is interposed between a cell element and a cover member in a nonaqueous electrolyte secondary cell including the cell element formed by stacking cathodes and anodes through separators, a cell can including a can body which houses the cell element and the cover member which closes an opening of the can body to seal the cell element, and an electrolyte injected into the cell can. The insulating plate includes a plate-shaped insulating plate body having insulating property, an injection hole which passes through the insulating plate body in the thickness direction and through which the electrolyte can be injected, and a filter member permeable to only the electrolyte and provided on one of the surfaces of the insulating plate body so as to cover the injection hole.

Description

technical field [0001] The present invention relates to an insulating plate of a nonaqueous electrolyte secondary battery, a nonaqueous electrolyte secondary battery, and a method for manufacturing the insulating plate of the nonaqueous electrolyte secondary battery. Background technique [0002] like Figure 16 As shown, a wound nonaqueous electrolyte secondary battery (lithium ion battery) 100 includes a battery element 101 as a power generating element and a nonaqueous electrolyte solution 102 as an ion moving medium between positive and negative electrodes. The battery element 101 and the nonaqueous electrolyte solution 102 are housed in a cylindrical can 103 whose bottom is made of conductive metal or the like. The opening of the can body 103 is sealed by the lid member 104 so that the inside thereof is sealed in an airtight state. [0003] The battery element 101 includes a strip-shaped positive electrode 105 and a strip-shaped negative electrode 106. The strip-shaped...
