注液していた。Go to 2 - Conventional technology Conventionally, batteries constructed using alkali metals such as lithium and sodium, alkaline earth metals such as calcium, or light metals such as aluminum as negative electrode active materials have a negative electrode active material whose electronegativity is Because it is large, it is possible to obtain a battery with high voltage and high energy density by combining it with a suitable positive electrode. Since this negative electrode metal easily reacts with moisture to release hydrogen gas and self-discharge, an aqueous solution cannot be used as the electrolyte, and esters such as propylene carbonate, ethylene carbonate, γ-butyrolactone, etc. 1. Organic solvent alone consisting of ethers such as 2-dimethoxyethane, dibutoxyethane, dibutoxyethane, etc.
Alternatively, LiBF4. LiCIO4
,L:1F5So3. A salt consisting of a halide such as LiAsF6LiPF6 was used alone or in a mixture of several kinds to increase the electrical conductivity of the electrolytic solution. In addition, since this type of battery has high voltage and high energy density, the purpose of this battery is to prevent or alleviate the possibility of the battery exploding when it encounters an abnormal condition such as a short circuit, charging, or being thrown into a fire. It is customary to provide a safety valve on the sealing plate. 1. When injecting electrolyte into a battery with such a configuration, it is important to inject as much electrolyte as possible as quickly as possible, taking into consideration workability and battery performance. For this reason, when injecting the electrolyte, the battery is immersed in the electrolyte, or the battery is injected under reduced pressure, or by applying centrifugal force.
このため、注液時に前記封口板のガス抜き孔から電解液
が封口板の内部に侵入する事がある。Therefore, during injection, the electrolytic solution may enter the interior of the sealing plate through the gas vent hole of the sealing plate.

に悪影響を及ぼすことがあった。More than just the problem that the invention aims to solve, the safety valve and gas exhaust hole are provided on the battery sealing plate, which makes it easier to configure the battery (when pouring electrolyte).
Electrolyte often enters through the gas exhaust hole. In this case, even if the battery is cleaned in the next step, a small amount of the electrolyte remains in the sealing plate. As mentioned above, the electrolyte is made by dissolving a solute such as a halide in one or more kinds of organic solvents, so when the battery is stored, the organic solvent gradually vaporizes or leaks out, causing the gas exhaust hole to open. In some cases, solute crystals may precipitate in the parts, which may have an adverse effect on the electrical contact with the equipment used.

In the figure, the person is a plate plate B, which is a valve body that expands upward as the internal pressure of the battery rises, and has a valve hole B1 in its center, and a terminal plate C, which has a cutting blade C1 and a gas vent hole C2 at its top. The sealing plate G is constructed by bending the bent portion B2 of the plate plate inward and fixing the valve body A of n11 by caulking. Therefore, when an abnormality occurs in the battery and the battery internal pressure rises, the valve body bulges upward, and the valve body 61 and 7 are destroyed by the cutting blade C1 provided on the terminal board C, and the gas inside the battery is released from the gas vent hole. Scattered. D is a metal case that houses the power generation element E. Power generation element E has manganese dioxide as the main active material as a positive electrode, and graphite and acetylene black are mixed as conduction aids. Dl is electrically connected to the plate B of the sealing plate G by the lead piece of the positive electrode. The negative electrode lead piece is electrically connected to the inner bottom surface of the metal case D (not shown).
