Zinc Carbon Battery-Advantages And Limitations

At the end of the 19th century, Carl Gassner further developed the zinc carbon battery on the original basis, which brought great innovation to the whole battery field. It also provided portable power for the popularization of portable electrical equipment.This article will analyze the characteristics of zinc carbon battery from different angles, and make an objective evaluation on the value of zinc carbon battery.

Are zinc carbon batteries good 

First of all, we need to understand the construction of zinc carbon batteries. The positive and negative electrodes of zinc carbon battery are composed of manganese dioxide and zinc metal respectively, and there is a porous carbon rod in the center of the battery. The main components of electrolyte are ammonium chloride and zinc chloride, and the main component of separator is starch. It can be said that the zinc carbon battery was excellent in its generation, because before the birth of zinc carbon battery, the commonly used batteries were large in volume and the shell was made of fragile glass. This is because the batteries before the zinc carbon battery basically used acid electrolyte with high corrosion resistance. The carbon rod design concept of the zinc carbon battery center is also quite ingenious. Its main purpose is to collect current and provide support for the battery structure. However, it can also release reaction gas and prevent oxygen from corroding zinc metal.

Zinc carbon battery can be said to be a milestone in the history of battery development. It has been popular for nearly half a century, and has also expanded the application field of battery. Many portable electrical equipment such as flashlight are widely used with the popularity of zinc carbon battery.

According to the data, zinc carbon battery is mainly divided into two types, one is the Leclanche battery, which is the earliest zinc carbon battery, and it is also the earliest widely used battery. The discharge performance of Leclanche battery is poor in low temperature and high temperature environment, so this kind of battery was later improved by Carl Gassner to a new type of zinc chloride battery, which is another kind of zinc carbon battery. The capacity of zinc chloride battery is increased by about 50% compared with that of the Leclanche battery. Its current capacity and low-temperature discharge performance are also better, and its shelf life is much longer than that of the Leclanche battery.

Can zinc carbon battery be recharged 

Don’t recharge your zinc carbon battery, it could be dangerous. Zinc carbon battery belongs to disposable battery, it can not be recycled through charging. The design concept of zinc carbon battery has not considered that the battery needs to be charged. If you try to recharge it, it may cause the risk of battery leakage or even explosion.

In fact, zinc carbon battery can be charged by special methods by theory, but this kind of charging is very limited. You can recover part of the charge for the zinc carbon battery through a special charger with protection device. It should be noted that only part of the charge can be recovered. We cannot fully charge this kind of battery. And every time you charge it, its capacity will drop sharply and become useless after a few short cycles. Therefore, charging the zinc carbon battery may be an interesting attempt, but this method is not practical at all, and it is likely to cause safety accidents if safety precautions are not taken. So if you want your battery to be recycled by charging, buy rechargeable secondary batteries, such as lithium-ion batteries.

What are the advantages and limitations of zinc carbon battery 

Compared with its previous generation, zinc carbon battery has many advantages:

·Its production and use cost is very low, even in modern times, its price advantage also does not make it be completely eliminated by the market.

·Zinc carbon batteries come in a variety of models and specifications, and are easily available in the market. There are A, AA, AAA and other types of zinc carbon battery in size, and different types of zinc carbon battery can meet different electricity demand.

·The shell is sturdy and reliable. Compared with the glass case battery, the zinc carbon battery shell is enough to support its use in a variety of portable devices.

·The energy density of carbon zinc battery is higher than that of its predecessor. The discharge efficiency and capacitance of the carbon zinc battery are higher than those of its previous generation, which means that its use will be more efficient and lasting. But this advantage for modern batteries, is like shooting fish in a barrel.

Compared with the modern popular lithium battery, zinc carbon battery also has many limitations:

·The energy density of lithium battery is much higher than that of zinc carbon battery, and the discharge performance of lithium battery is much better than that of zinc carbon battery. The average voltage of normal lithium battery is 3.7V, while that of zinc carbon battery is only about 1.5V. It can be said that zinc carbon battery can not compare with modern lithium battery in discharge efficiency and in capacity.

·Zinc carbon batteries are not rechargeable, while lithium batteries can be recharged and reused after full discharge. The cycle life of lithium battery can reach 1000 times, which means that the total effect of a lithium battery may exceed 1000 zinc carbon batteries. In contrast, the price advantage of zinc carbon battery does not seem to bring it the same performance price ratio as rechargeable lithium battery.

·The safety of zinc carbon battery is poor. This is mainly reflected in its poor oxidation resistance, low leakage resistance and easy wear of negative electrode. Because the negative electrode of zinc carbon battery is zinc metal, and these zinc metals also act as the shell of negative electrode, they are easy to be corroded by oxygen, and they are easy to be worn in daily use, which will affect the capacitance of the battery.

Although zinc carbon battery has been popular for a long time, it will be eliminated with the rapid development of battery technology.
