摘要： An insulating plate for a secondary battery includes a wound electrode group, an electrolyte, a cylindrical battery case that houses the electrode group and the electrolyte, and a sealing body that seals an opening of the battery case and includes a discharge valve. The insulating plate is disposed between the electrode group and the sealing body and has a disk shape with a thickness T of 0.1 mm or more. The insulating plate has a first hole formed centrally therein and at least one second hole formed around the first hole so as to extend along the outer periphery of the disk shape. The ratio (=T/D) of the thickness T to a diameter D of the insulating plate is 0.016 or less, and the insulating plate has an opening ratio of 36% or less.

摘要： A cylindrical lithium ion battery in which an electrode group formed by winding a positive electrode and a negative electrode is housed in a battery case is disclosed. A sealing plate seals an opening of the battery case. An insulating plate having a plurality of openings is provided on a side of the electrode group closer to the sealing plate. The plurality of openings include a first hole with a largest opening area, and a plurality of second holes with opening areas smaller than the opening area of the first hole. An opening ratio of the first hole is 12% or more and 40% or less; a sum of opening ratios of the second holes is 0.3% or more and 10% or less; and a total opening ratio of all the openings is 20% or more and 50% or less.

摘要： The secondary cell—includes an exterior can, a sealing body closing one end of the exterior can, an electrode group disposed inside the exterior can, and an insulating plate disposed between the sealing body and the electrode group. In the electrode group, a positive electrode and a negative electrode are wound in a spiral shape with a separator interposed between. The insulating plate is shaped as a disc having a lead hole penetrated by a positive electrode lead drawn out from the electrode group, and a center hole penetrating the center part of the insulating plate. The outer edge of the lead hole includes a curve part positioned along an arc that is concentric with respect to the outer circumference of the insulating plate as seen in plan view, and linear parts-positioned along a chord linking the two ends of the arc.
