- sample numbers 1 to 20 the samples (sample numbers 1 to 20) of the plated steel sheets for battery containers shown in Tables 2 to 5 were prepared. As shown in Tables 6 to 9, for comparison, samples in which a dispersed plating layer was not formed (sample numbers 21 to 34) were also prepared.
- Ni containing Yes amount (g / m:) kind containing organic weight (g / m 2) (g / m 2)
- the outer side of the container was provided with the iron-nickel alloy layer and the nickel layer only, and the outer surface was then squeezed by a 10-step drawing process. It was formed into a cylindrical LR6 type battery (AA battery) container with a diameter of 13.8 mm and a height of 49.3 mm.
- AA battery AA battery
- an alkaline manganese battery was prepared as follows. Manganese disulfide and manganese were collected at a ratio of 10: 1, and potassium hydroxide (10 mol) was added and mixed to prepare a positive electrode mixture. Next, the positive electrode mixture is pressurized in a mold to form a donut having a predetermined size. The resulting mixture was formed into a positive electrode mixture pellet having a shape, and pressed into the battery container. Some of the battery containers used had inner surfaces coated with paint containing graphite powder as a main component. Next, the negative electrode plate on which the negative electrode current collector was spot-welded was mounted on the battery container.
- a vinylon woven fabric separator having a strong force is inserted along the inner periphery of the positive electrode mixture pellet pressed into the battery container, and the zinc oxide and potassium hydroxide are saturated with zinc oxide.
- the negative electrode gel was filled in the battery container.
- an insulator gasket was attached to the negative electrode plate, inserted into the battery container, and then subjected to a cashmere process to produce an alkaline manganese battery.
- the battery After leaving the battery at 80 ° C for 3 days, the battery was discharged to a constant current of 1.5A and the voltage was 0.9
- the time to reach V was measured as the discharge time. The longer the discharge time, the better the discharge characteristics.
- the operation of discharging at 2A for 0.5 seconds and then discharging at 0.25A for 29.5 seconds was defined as one cycle, and this cycle was repeated until the voltage reached 1.0 OV.
- the number of cycles was measured. The more cycles, the better the intermittent discharge characteristics.
- Tables 10 and 11 show the results of these characteristic evaluations.
- the present invention is a.
- a metal layer containing ultrafine carbonaceous carbon nanotubes or ultrafine carbonaceous materials and fine carbonaceous materials such as Ketjen black and acetylene black is provided on the inner side of the battery container.
- a metal layer containing ultrafine carbonaceous material or ultrafine carbonaceous material and fine carbonaceous material is formed in which a metal layer containing ultrafine carbonaceous material or ultrafine carbonaceous material and fine carbonaceous material is formed.
- Flow, discharge characteristics, and intermittent discharge characteristics were obtained.
- a graphite paint was applied to the inner surface of the battery using the plated steel sheet for a battery container of the present invention, the short-circuit current, discharge characteristics, and intermittent discharge characteristics were further improved.
- the battery of the present invention using the battery container-attached steel sheet in which a metal layer containing ultrafine carbonaceous material or ultrafine carbonaceous material and fine carbonaceous material is formed on the side serving as the inner surface of the battery container is provided on the inner surface of the container. Even when used without applying graphite paint, it shows better short-circuit current, discharge characteristics, and intermittent discharge characteristics than the case of using a container with graphite paint applied to the inner surface of a conventional container. Therefore, the steps of applying and drying the graphite paint can be omitted, and the battery can be manufactured at low cost.
