いう欠点を有していた。[Detailed Description of the Invention] The present invention relates to the leakage characteristics of a non-aqueous electrolyte battery that uses manganese dioxide as an active material and lithium as a negative electrode active material. The current consumption of devices is decreasing year by year, and batteries used as power sources are also required to have a longer lifespan due to lower current consumption.Silver batteries were mainly used as these batteries, but recently, Non-aqueous electrolyte batteries that use lithium, which has a higher energy density, as the negative electrode, have come into use.Non-aqueous electrolyte batteries have the advantage of being more resistant to leakage than silver batteries, but they are not suitable for long-life devices. Since it is used for a long period of time, it has the disadvantage that leakage may occur over a long period of time.

A negative electrode lithium 2 is crimped onto a negative electrode can 1 which has been integrated with an insulating gasket 5 in advance to form a negative electrode unit. Incorporate a separator 3° electrolyte and a positive electrode mixture 4 mainly consisting of manganese dioxide into the negative electrode unit, set the positive electrode can 6 and perform crimping, and make a CR2016 battery with an outer diameter of 20 pieces and a total battery thickness of t6. Assembled. Level f+ of positive electrode can height after crimping, 51wL, 1.27m, 1.

ットの圧縮率が増加する為であり、特にＡ部の圧縮率の
増加が太きい。Table 2 As is clear from Table 2, the battery with the old electrode can height of 1.25 ya has excellent leakage resistance. This f''L is due to the increase in the compression ratio of the insulating gasket by lowering the height of the positive electrode can after crimping, and the increase in the compression ratio of the A section is particularly large.

上重要であり、Ｂ部の圧縮率は３５チ以上必要である。In this example, the total height of the battery was kept constant, and all crimp conditions were adjusted so that the height of the positive electrode can was at the above level, so that changes in the internal volume of the battery were minimized. The compression ratio of the A section of the insulating gasket is preferably 70% or more. Father, the compression of part B of the insulating gasket is easily affected by the shape of the bottom of the negative electrode can, and although the compression ratio of part A is not high, it is important for leakage resistance, and the compression ratio of part B is 35 inches or more. is necessary.

のは当然であり、注意が必要である。Increasing the compression ratio of the insulating gasket has a large effect on leakage resistance, and is particularly important in a structure in which there is no risk of separator breakage. However, limp conditions that cause deformation of the negative electrode can naturally have an adverse effect on leakage resistance, so care must be taken.
以上記載した様に、クリンプ条件の変更のみで、経済的

価値の極めて大なるものである。As described above, an invention that can economically provide a battery with excellent leakage resistance by simply changing the crimp conditions is of extremely great industrial value.
