A non-aqueous electrolyte prepared by dissolving a lithium salt such as AsF 6 or LiPF 6 is used, and compounds such as vanadium oxide, cobalt oxide, and manganese oxide are mainly used as the positive electrode active material.

め洗浄を行いこれらの発生を防いでいた。By the way, when using a non-aqueous electrolyte,
Since the electric conductivity is low, it is necessary to sufficiently fill the battery with the electrolytic solution. Also, unlike the aqueous system, the non-aqueous electrolyte system is
Since it has no creeping property and does not show progress even when the sealing portion is wet with the electrolytic solution, the electrolytic solution is excessively injected to assemble the battery. Therefore, the electrolyte solution overflows when the battery is sealed. As a result, rust is generated due to the effect of the lithium salt in the electrolyte that has adhered to the outer peripheral surface of the battery after the battery is assembled, and the battery function is degraded. However, the appearance of the battery may be lost due to deposition on the flat surface of the positive electrode terminal or contamination with a non-volatile solvent. Therefore, cleaning was performed to prevent these occurrences.

行っていた。In the conventional cleaning, as shown in FIG. 3, the battery 1 is placed so that the flat surface of the negative terminal of the battery 1 or the flat surface of the positive terminal faces the conveyor 3 so that the flat surface thereof faces upward, and the battery 1 is blown off. Cleaning is performed with a hot water shower 5 from a nozzle 4 to which water pressure that is not applied is blown, and then air with a pressure that does not blow the battery 1 is blown to blow away water adhering to the battery periphery or the surface.

A method of immersing it in the ultrasonic cleaning tank 6 contained therein has also been performed.

投入し両面を洗浄する等の方法をとっていた。However, with these cleaning methods, although one side of the battery can be cleaned, both sides of the negative electrode terminal and the positive electrode terminal cannot be cleaned. Therefore, in the case of cleaning both sides, a method of reversing the up-down direction of the battery after cleaning the negative electrode terminal or the positive electrode terminal by 180 ° and re-inserting it in a cleaning machine to wash both surfaces has been adopted.

One side may be washed, and the contaminated cleaning fluid may flow to the other side, and the other side may be rather dirty. Therefore, as a final finish, the battery was hand-wipe with gauze or the like to prevent the formation of rust and the precipitation of lithium salt crystals.

Substantially since the washing by rotating the battery in a plane parallel to the surface portion, the portion exposed to the surface, such as conveyor will only side surface portions. In addition, since the battery is constantly rotating, the side surface is also cleaned so that there is no fear of contamination. As a result, both surfaces of the positive electrode terminal and the negative electrode terminal of the battery can be cleaned at the same time, and it is possible to eliminate the possibility of contaminating the battery again with the contaminated cleaning liquid.

Stand with the negative electrode terminal flat portion and the positive electrode terminal flat portion in the vertical direction and are substantially parallel to the negative electrode terminal flat portion and the positive electrode terminal flat portion.
The battery is inserted into the battery transport jig 2 that can be rotated once or more during cleaning in a plane. The traveling speed of the battery conveying jig 2 at this time is set so as to be different from the traveling speed of the conveyor 3. This allows the battery 1
Can be rotated, but in this case, the larger the speed difference, the more the number of rotations of the battery 1 increases and the cleaning becomes uniform. Preferably, the speed difference can be further increased by reversing the traveling direction of the conveyor 3 and the traveling direction of the battery carrying jig 2.

まうからである。Next, shower nozzles 4 to 6 arranged on both sides of the battery transport jig 2 on the negative electrode terminal side and the positive electrode terminal side.
A 0 ° C. hot water shower 5 is sprayed on the entire battery 1. The temperature of the washing water at this time is preferably 40 ° C to 80 ° C. More desirably, 50 ° C. to 70 ° C. is more effective in cleaning. This is because when the water temperature is 40 ° C. or lower, the electrolytic solution becomes difficult to dissolve, and when the water temperature is 80 ° C. or higher, the electrolytic solution is decomposed by heat and the battery performance deteriorates.
