Abstract

PURPOSE:To increase storage life and assembly efficiency of a battery by using lithium iron disulfide as a negative active mass. CONSTITUTION:Mixed powder comprising, for example, 90pts.wt. lithium disulfide as a negative active mass, 6pts.wt. acetylene black as a conductive mass, 4pts.wt. fluorine resin powder as a binder is pressed under, for example, a pressure of 3T/cm<2> to mold, and then heat-treated to make a negative electrode. This process can increase storage life and simplify assembly of a battery.

Description

[Detailed description of the invention] The present invention relates to improvements in organic electrolyte batteries.

As this type of battery, an electric battery with a battery voltage of 1.5 vA is being studied, which uses lithium as a negative electrode active material and fluoride carbon dioxide or carbon dioxide as a positive electrode active material.

However, the problem with the seed battery is that the lithium used as the negative electrode active material is extremely reactive with moisture, so the amount of water contained in the positive electrode and the iron cast iron, which is an electromagnetic groove-rich element, is It is necessary to reduce the VC1it as much as possible, but there is a problem with storage stability because it is not possible to make kernels that contain virtually no moisture, and the electrical assembly is carried out in a dry box surrounded by argon, which has a low moisture content. The disadvantage is that the work must be done under specific circumstances, making the work complicated.The present invention was made in view of this problem.

Iron disulfide as a negative active material ('L1νe8 leak)
By using this, the storage performance of the Jinnotane battery is improved and there are no particular limitations when assembling the battery. lq
This improves the performance by making it possible to perform in Daichi Junior High School without having to perform under L.

Reproduction of fish species: Iron disulfide as a negative electrode active material? A
(LIP-1) 90 parts by weight, 1 cetia as a conductive agent
It is molded and heat treated at about 500°C to form a negative electrode.

Positive Ik is manganese dibenzene 90]1tsI as the active material

Mixed powder consisting of iE and 4 parts of fluorine fat powder as a binder and 11 parts of 1fi! After molding, heat treatment was performed at approximately 300°C.

The electrolyte was prepared by dissolving 1 molar concentration of lithium perchlorate folate in a mixed solvent of equal volumes of propylene carbonate and 1.2 dimethoxyethane, and the separator was made of polypropylene nonwoven fabric with an outer diameter of 25 mm and a height of 2.8 mm. Figure 0, which shows a 1.5V organic electrolyte battery, shows the 5.6Ω constant load discharge characteristics of the battery of the present invention.

In the figure, (A) is a Vi uninvented battery, and (B) for comparison, lithium is used as the negative active material and iron disulfide (iron disulfide) is used as the positive electrode active material.
This is a comparison battery using Fe81). 41 is the initial characteristic, and FIII is the discharge characteristic after storage at 60°C for one month.

As is clear from this characteristic diagram, it can be seen that the storage performance of the battery of the present invention has been improved.Compared to the battery of the present invention, there is almost no influence of moisture on the old strain or Hirosada Den. It is said to have good storage performance and is said to have been tatami-matted.

Father, Nisei iron lithium uses dimpled lithium, which can be handled in the atmosphere without any problems. There is also the advantage that the battery assembly work is simpler than in the case of the conventional method.

Note that the present invention is not limited to unused batteries, i-order batteries, and secondary batteries.

The present invention relates to an organic electrolyte battery, which improves storage performance and simplifies battery assembly work by using lithium iron disulfide as a negative active material. The target value i [Fi is extremely large.
