The present invention relates to a non-aqueous electrolyte battery using metallic lithium as a cathode active material and metal sulfide as an anode active material. This type of non-aqueous electrolyte battery has a larger current capacity per unit volume than non-aqueous electrolyte batteries that use manganese dioxide or carbon fluoride as the anode active material.
It also has features such as a discharge voltage of 1.3 to 1.5V, making it compatible with Lecrancier batteries and silver oxide batteries. However, as this battery discharges, Li 2 S is generated and accumulated on the anode side, which causes the anode to swell and increase the overall height of the battery, resulting in damage to equipment using the battery and the need for contact. The present invention effectively eliminates the above-mentioned drawbacks by adding an alkyl halide to a non-aqueous electrolyte. Alkyl halide is represented by the general formula RX,
In the formula, R is methyl, ethyl, propyl, isopropyl, butyl, isobutyl, sec-butyl, tert-
Alkyl groups such as butyl, n-amyl, isoamyl, hexyl, heptyl, octyl, nonyl, and decyl. Moreover, X in the formula is a halogen such as fluorine, chlorine, bromine, and iodine. Next, embodiments of the present invention will be described with reference to the drawings.
A mixture of 88 parts by weight of ferrous sulfide, 10 parts by weight of phosphorous graphite, and 2 parts by weight of polytetrafluoroethylene is molded under pressure to produce an anode 1 having a diameter of 11 mm and a thickness of 0.85 mm. This anode 1 is inserted into an anode can 2 made of a 0.25 mm thick Ni/SUS clad plate with an outer diameter of 11.6 mm and a height of 3.0 mm, and an electrolyte absorber 3 made of polypropylene is placed on top of the anode can 2.
A polypropylene annular gasket 4 having an L-shaped cross section is fitted into the opening of the anode can 2. The electrolyte absorber 3 contains propylene carbonate and 1.2-
An electrolytic solution prepared by dissolving 1 mole of lithium perchlorate in a solvent mixed with dimethoxyethane at a volume ratio of 1:1 is injected and impregnated with 10% by weight of alkyl halide. Separately, a stainless steel net 6 with a thickness of 0.1 mm and a diameter of 6.0 mm was welded to the inner surface of the cathode terminal plate 5, which was made of a Ni/SUS clad plate with a thickness of 0.25 mm and had an outer diameter of 10 mm and a height of 1.5 mm. Net 6, diameter 8.0mm, thickness
A 1.2 mm cathode 7 made of metallic lithium is crimped. Next, the cathode terminal plate 5 containing the cathode 7 is inserted into the gasket 4, and the open end of the anode can 2 is bent inward to assemble a button-shaped battery having a total height of 2.90 mm. The following table shows the discharge capacity and total height of the battery after discharge when this battery was discharged at 20°C with a 6.5kΩ resistor until the terminal voltage reached 1.0V.

[Table] As is clear from this table, by adding an alkyl halide to the electrolytic solution, the swelling of the battery due to discharge can be suppressed to a small level, and the discharge capacity can be increased. The optimum addition rate of alkyl halide differs somewhat depending on the type of alkyl halide, but if any alkyl halide exceeds 20% by weight, the discharge capacity will decrease, so it is preferably 20% by weight or less. Although ferrous sulfide was used as the anode active material in the above example, the same method can be applied to nonaqueous electrolyte batteries using other materials such as ferric sulfide, iron disulfide, copper sulfide, and nickel sulfide as the anode active material. Effects can be obtained. The present invention has the above-described configuration, and can suppress the swelling of the battery due to discharge.
Various harmful effects caused by swelling are eliminated.
