Manufacturing process of FUJITSU batteries

FUJITSU Alkaline Battery FUJITSU Carbon-Zinc Battery
Properly speaking, the Alkaline battery is called an Alkaline-Manganese Dry Battery. It looks nearly the same as the conventional carbon-zinc battery in shape and profile but its performance is vastly differernt; it can deliver high-level power(up to seven time or more as large as thet of the manganese battery) for many hours of continuous use with a small voltage drop. Made with manganese dioxide and zinc as prime materials, the carbon-zinc, battery is one of the most widely used batteries. When a voltage drop begins after hours of use, you can continue using the battery at a satisfactory level of performance by letting it operate and rest at intervals. The battery is suitable for use in a powerful light, a flash light, a calculator, etc.
1 1
Degreasing a cathode can ZINC CAN
Any oil on a can are removed. This can functions as a positive electrode. Therefore, materials must be put from the negativ side. A zinc can functions as both a container and anode material.
2 2
Applying a conductive film Inserting a separator
A conductive material, is sprayed to form a conductive film on the inside surface of a cathode can for good electrical conductivity. A separator and a bottom paper are inserted to prevent short-circuit of a positive and a negative electrode.
3 3
Inserting cathode materials Filling cathode material
Cathode materials, mixture of manganese dioxide, carbon and others as positive electrode are inserted into a cathode can. A mixture of manganese dioxide, electrolyte and others are filled as a cathode material.

Inserting a separator Inserting a carbon rod
A separator is inserted to prevent short-circuit of a positive and a negative electrode. A carbon rod for collecting electricity is inserted into the center of a Zinc can.
5 5
Injecting electrolyte Sealing
An electrolyte is injected into a separator to generate electricity. A plastic gasket for sealing is fitted to prevent leakage and drying.
6 6
Injecting anode gel Fitting a negative terminal and resin tube
An anode gel of zinc particles and an alkaline solution is injected as the material of a negative electrode. A negative terminal and a washer are placed on the bottom of Zinc can and shrinkbwrapped by resin tube.
7 7
Inserting a current collector Putting the terminal and metal jacket
An assembled current collector is inserted from the negative electrode side. This current collector functions as an anode terminal. A positive terminal and a washer are placed on the top of battery and covered by a metal jacket.

Sealing Inspection
A battery is sealed to prevent leakage and drying. A battery is inspected on its voltage, current and appearance.
A battery is affixed with a label.
A battery is inspected on its voltage, current and appearance.

The Batteries are packed in export cartons The batteries are transported to the port. The batteries are shipped to the customers all over the world The FUJITSU
batteries are sold at the super markets, electronics shops, photo shops, drug stores, department stores, etc.
