First, carbon batteries and alkaline batteries are both dry batteries, and bai is only divided into
two categories according to different materials.
Second, the full name of a carbon battery should be a carbon-zinc battery (because it is generally
a carbon rod for the positive stage and a zinc skin for the negative electrode), also known as a
zinc-manganese battery, which is currently the most common dry battery. It has low price and
safe use. Reliable features. Because carbon batteries contain heavy metal cadmium, they must
be recycled to avoid damage to the global environment. (So the positive grade we usually use
is carbon rod, and the negative electrode is zinc skin batteries to be recycled).
Third, alkaline batteries are also called alkaline dry batteries or alkaline zinc-manganese dry batteries,
which are suitable for instruments that require large discharge and long-term use. The internal
resistance of alkaline batteries is lower, so the current generated is larger than that of ordinary
zinc-manganese batteries. , While the environmentally friendly alkaline battery contains only
0.025% mercury and does not need to be recycled. Based on the environmental protection and
high current characteristics of alkaline batteries, more alkaline batteries are now offered.
Fourth, the nominal voltage of both carbon and alkaline batteries is 1.5V, but alkaline batteries
of the same volume have a larger capacity and are more suitable for high-current discharge.
Fifth, the essential difference between carbon batteries and alkaline batteries is the difference
in internal materials. In short, carbon batteries are composed of carbon rods and zinc skins,
but there are cadmium and mercury inside, which are not conducive to environmental protection,
but they are cheap, so they still have a place in the market. Alkaline batteries do not contain
heavy metal ions and have high current. Conducive to environmental protection is the direction
of future battery development!
Sixth, alkaline batteries are 4-5 times the capacity of carbon batteries, and the price is 1.5-2
times that of carbon batteries. Carbon batteries are suitable for low-current electrical appliances,
such as quartz clocks, remote controls, radios, etc.; alkaline batteries are suitable for high-current
electrical appliances, such as BP players, CD players, electric toothbrushes, electric toys, and
handheld computers.
