What is the Reason for the Popularity of Alkaline Batteries?

Alkaline batteries, also known as alkaline dry batteries, alkaline zinc-manganese batteries, and alkaline-manganese batteries, are the best-performing varieties in the series of zinc-manganese batteries. Suitable for large discharge and long-term use. The internal resistance of the battery is low, so the current generated is larger than that of ordinary carbon batteries. Because these batteries do not contain mercury, they can be disposed of with household waste without deliberate recycling.

What is the reason for the popularity of alkaline batteries?

Alkaline batteries have lower internal resistance, so the current generated is larger than that of ordinary carbon batteries. alkaline batteries do not contain mercury, so they can be disposed of with household waste without deliberate recycling. When an alkaline battery is discharged, no gas is generated inside, while some gas is generated when an ordinary dry battery is discharged, so the voltage of the alkaline battery is relatively stable. Alkaline batteries have a large capacity and can be used for longer than ordinary carbon batteries, so they are more cost-effective and are very popular among consumers.

What is the chemical reaction process of alkaline batteries?

The cell is expressed as (-)Zn|NaOH|MnO2(C)(+)

Cell reaction

Negative reaction Zn+4OH--2e→ZnO22-+2H2O

Positive reaction MnO2+H2O+e→MnO(OH)+OH-

Total reaction Zn+2MnO2+2OH-→ZnO22-+2MnO(OH)

Alkaline batteries are normally used at the same voltage as the common acidic zinc-manganese batteries. alkaline batteries have long life, large capacity, small internal resistance, and will not leak after a long time of use like dry batteries, so it is the preferred power source for personal audio, cameras, etc.

What is a rechargeable alkaline battery?

A few electronics companies have developed "rechargeable alkaline batteries" to strengthen the battery structure to avoid breakage, but it cannot improve the low charging efficiency. It can only be charged with a relatively small current, and it often takes a whole day or more to fully charge. The number of battery recharges is very small, which is quite inconvenient, and has now been eliminated from the market.

In addition, some electronic companies have developed alkaline battery chargers, claiming that they can charge general "disposable alkaline batteries", but they are still limited by the slow charging of alkaline batteries, low efficiency, and very few recharge cycles (less than 10 on average). Under long-term charging, excessive waste heat is accumulated during the step-down conversion process of the charger, which may waste more energy and is not environmentally friendly. Compared with Ni-MH batteries, it has many disadvantages.

This kind of product does not guarantee absolute safety in the instructions for use, and does not guarantee the performance of the fully charged battery and whether it is more likely to leak.

Guangzhou Dolphin Information Technology Co., Ltd., which has been established for over ten years, focuses on the production of alkaline batteries. Here, you can find the alkaline batteries you need.
