1, different manufacturing materials
Gold battery: The gold battery is made of Ni-MH material, which is mainly composed of positive electrode, negative electrode, diaphragm and electrolyte. The electrolyte is mainly liquid, and the main component is potassium hydroxide (KOH).
Wei Chao black gold battery: Wei Chao black gold battery is made of alkaline zinc and manganese, with potassium hydroxide as electrolyte.
2. Different application fields
Gold battery: gold battery is suitable for small current discharge and can be used in calculators, remote controllers, quartz clocks, telephone landlines, etc.
Wei Chao black gold battery: Wei Chao black gold battery is suitable for high-current continuous discharge, and can be used for battery cars, electric cars, car backup batteries, etc.
3. The difference between positive electrode and negative electrode
Gold battery: The positive electrode of a gold battery is a nickel electrode (Ni(OH)2), and the negative electrode is generally a metal hydride (MH).
Wei Chao black gold battery: Wei Chao black gold battery uses manganese dioxide as the positive electrode and zinc as the negative electrode.
