The battery is one of the key materials that toy structural engineers often touch. The degree of understanding of the battery is also an important factor in testing whether a toy structural engineer is qualified.
Then the question is coming. Can you judge the alkaline battery and the nickel-hydrogen battery from the battery skin?
First, the alkaline battery skin is an aluminum film sticker, and the nickel-hydrogen battery is a high temperature resistant film. Secondly, the positive end of the nickel-hydrogen battery is completely wrapped, only the end is exposed, and the alkaline battery is allowed to be exposed on the entire surface.
The battery materials and packaging methods of the two batteries are different because of their different performance and structural characteristics. The difference in materials is well understood. Alkaline batteries are disposable batteries, so they use inexpensive aluminum foil stickers. Nickel-metal hydride batteries and rechargeable batteries need to be used repeatedly, and the battery temperature rises during charging, so it is necessary to use a high-temperature resistant PVC film as the battery skin.
The positive and negative electrodes of the alkaline battery are separated from the two ends of the battery, and even if the electrodes at both ends are exposed, it is difficult to contact anyway. The negative electrode of the nickel-metal hydride battery is directly connected to the battery case, so that if the positive electrode end is not well separated, it is easy to cause a short circuit.
CIXI BRIGHTER BATTERY CO.,LTD is established in 1997, has over 20 years of manufacturing experience,It is the alkaline battery manufacturers and alkaline dry battery wholesalers in China.
