Battery Batch

The alkaline battery can take the square or cylindrical form that we all know so well. The contents are contained safely within a steel casing. The cathode, which is the negative part of the battery, is a compressed mixture of manganese dioxide paste and carbon powder. The center of the cathode is hollow and lines with a conductive separator to prevent the cathode and anode materials from mixing, but allowing their varying electrical potentials to pass from one to the other. The anode is the positive part of the battery and contained within the center of the cathode. It’s a gel of potassium hydroxide and zinc powder.
