Carbon cell
Carbon batteries are also called dry batteries, which is relative to batteries with flowing electrolytes. Carbon batteries are suitable for flashlights, semiconductor radios, radio recorders, electronic clocks, toys, etc., mainly used for low-power electrical appliances, such as clocks, wireless mice, etc., high-power electrical appliances should use alkaline batteries, such as cameras, some cameras alkaline also can not hold, it needs to use nickel-metal hydride. Carbon batteries are the most widely used battery in our lives, and the earliest battery we have contact with should be this, which has the characteristics of low price and wide use.
The full name of carbon battery should be carbon zinc battery (because it is generally positive carbon rod, negative electrode is zinc skin), also known as zinc manganese battery, is the most common dry battery, it has the characteristics of low price and safe and reliable use, based on environmental considerations, because it still contains cadmium, so it must be recycled, so as not to cause damage to the earth environment.
The advantages of carbon batteries are obvious, carbon batteries are easy to use, cheap, and there are many types and prices to choose from. The natural shortcomings are very obvious, such as it can not be recycled, although the one-time input cost is very low, but the cumulative use cost can be very worthy of attention, and this battery contains mercury and cadmium and other harmful substances to cause damage to the environment.
Alkaline battery
The alkaline battery adopts the opposite electrode structure of the ordinary battery in the structure, which increases the relative area between the positive and negative electrodes, and replaces the ammonium chloride and zinc chloride solution with the highly conductive potassium hydroxide solution. The negative zinc is also changed from sheet to granular, which increases the reaction area of the negative electrode. In addition, high-performance electrolytic manganese powder is used, so the electrical performance is greatly improved.
In general, the same type of alkaline battery is 3-7 times the power of ordinary carbon batteries, the gap between the low temperature performance is larger, alkaline batteries are more suitable for large current continuous discharge and high working voltage requirements of the electrical occasions, especially for cameras, flash, shavers, electric toys, CD players, high-power remote control, wireless mouse, keyboard and so on to use.
ALKALINE battery identification can see whether the alkaline battery word or the Chinese word “alkaline battery” is printed.
How do you tell the difference between these two kinds of batteries?
- Look at the product logo
For the batteries we usually use, the category identification of alkaline batteries is LR, such as “LR6” for the No. 5 alkaline battery, “LR03” for the No. 7 alkaline battery; The category identification of ordinary dry batteries is R, for example, “R6P” is a high-power type No. 5 ordinary battery, “R03C” is a high-capacity type No. 7 ordinary battery. ALKALINE batteries also have the word “alkaline” - Different weights
The same type of battery, alkaline batteries are generally a lot more than ordinary dry batteries. - Touch with your hands
Because of the different packaging methods of the two, alkaline batteries can touch a ring slot near the negative end, and ordinary carbon batteries do not.
What do you need to pay attention to in daily use?
Although alkaline batteries have many advantages, the use time is also relatively long, and the power is sufficient. However, in daily use, be sure to use according to the instructions.
For example, the quartz electronic watch we commonly use is not suitable for alkaline batteries. Because for the clock, the clock movement only needs a small current to cope with, using alkaline batteries or rechargeable batteries will cause damage to the movement, resulting in inaccurate travel time, and even burn the movement, affecting the service life.
Carbon batteries are mainly used in low-consumption electrical appliances, such as clocks, remote controls, etc., and alkaline batteries should be used for larger power consumption, such as cameras, children’s toy car remote control cars, such as some cameras require larger nickel-metal hydride batteries.
Therefore, when choosing the battery, be sure to choose correctly according to the instructions.
