The difference between alkaline batteries and carbon batteries!

Commonly used 5 alkaline battery, 7 alkaline battery

Use LR6, LR03 to identify the model

And carbon cell number five and carbon cell number seven

Marked with R6, R03, no “L”

Distinguish between alkalinity or carboniness

Fastest way to see if there’s an “L.”
Alkaline batteries weigh more than carbon batteries

For example, the No. 5 alkaline battery weighs about 23 grams each

The No. 5 carbon battery weighs about 11 grams each

Another example is the No. 7 alkaline battery, which weighs 9g each

The number 7 carbon battery weighs 5g each

To the touch, the battery weight is different

The shell of the alkaline battery is a steel shell

The case of the carbon battery is zinc copper

The essential difference between carbon batteries and alkaline batteries

It’s the difference in the materials inside

Carbon batteries consist of carbon rods and zinc skins

However, there is cadmium and mercury inside, which is not conducive to environmental protection

So it’s cheap

Alkaline batteries do not contain heavy metal ions

Preventing leakage is good for the environment

Is the future direction of battery development
The alkaline battery is on the end near the bottom of the negative electrode

You can feel the annular slot

Carbon batteries generally do not have any slots on the cylinder

This is due to the two sealing methods are different

There are some carbon batteries on the market

It deforms when we squeeze it hard

The appearance of the alkaline battery is stainless steel, hard and not deformed
Alkaline batteries use electrolytic manganese dioxide to make a ring anode

Zinc powder and additives are configured with zinc paste as the negative electrode

Because the electrolyte is highly conductive

The surface area of anode and cathode materials is much better than that of carbon batteries

And the promotion of electrochemical reaction of zinc-manganese system under strong alkaline condition

The output power and capacity of the alkaline battery are far better than that of the carbon battery
