The difference between saline and alkaline batteries: features salt batteries, which are alkaline batteries

Many household appliances constant power supply is required for normal functioning. To this end, commonly used batteries. On sale you can find a variety of options for galvanic cells. But the most popular are alkaline and saline.

Both options are widely used in everyday life. At the same time, few people know that the difference between the elements is not only in the title.

Particularly salt batteries

Saline batteries - a simple device, wherein, in the chemical reaction produces electric current.

Reference. The second title salt batteries - carbon or carbon-zinc.

This battery has a low energy content, which explains its low cost. Therefore, the salt option is suitable for low-power devices, for example, the TV remote or hours. In devices with a high load or subject to frequent power surges necessary to use other batteries.

The product has a fairly simple structure, which includes:

1. Cathode. This battery housing is made of zinc. battery minus.
2. Anode. Is a plus. It is made by compression and additionally impregnated with an electrolyte.
3. Electrolyte. This substance, consisting of zinc chloride or ammonium chloride. To make a thicker consistency to it was added a small amount of starch.
4. Carbon conductor. It is located in the center of the battery. The outer part is coated with paraffin tokovoda composition.
5. Gas chamber. It is located at the top and is designed to collect gases, formed during the chemical reaction.
6. Laying. It is at the bottom. It makes the device watertight.

On the positive side the salt battery can be attributed not only to their low cost. They are also advantages:

• simple structure;
• ease of use;
• suitable for most household appliances.

The negative features include:

• high sensitivity to temperature changes;
• short term use and storage;
• the impossibility of re-charging;
• there is a risk of leakage of saline.

What are alkaline batteries

First alkaline battery invented by two American scientists: Waldemar Junger and Thomas Edison. It happened at the beginning of the twentieth century. But they became popular only after years.

Reference. Alkaline - in English means "lye". Therefore, the second name is alkaline alkaline batteries.

The design is not much different from the salt batteries. The main difference lies in the arrangement of the main parts. It also covers the anode and cathode. An anode performs zinc powder, which is impregnated with potassium hydroxide. The cathode is manganese dioxide with the addition of carbon black or graphite. Between them is a separator which is impregnated with additional electrolyte.

The cathode and anode are enclosed in a special housing that prevents a short circuit in the device.

The chamber is smaller, because during the chemical reaction produces a small amount of gas.

Also included in the design of bursting disc, which is needed to prevent a possible explosion of the battery. In the case of pressurizing the membrane will be broken off. Thanks to this device will be depressurized, and the electrolyte is spilled outside.

The advantages include:

• large amount;
• long service life;
• no self-discharge;
• reliable sealing of the case - so the battery can not be removed from the device, which you do not use, for a long time;
• It is included in the design of the valve, preventing the spontaneous explosion;
• High specific capacitance at low loads;
• It works at any temperature.

The disadvantages are:

• high price;
• sufficiently high weight;
• If the battery fails, it will be impossible to recover.

Due to the high charge capacity, alkaline batteries are widely used in various devices: high-power flashlights, cameras, various consoles, music players and others.

In various embodiments are presented for sale batteries. For convenience, all of them were marked the International Electrotechnical Commission:

1. "Tablets", "buttons" or "coin". They are small, round shape articles. Typically, they are used in a wristwatch, keychain signaling kitchen scales.
2. "Mizinchikovye" or mikropalchikovye. Are indicated by a combination of AAA. Made in the form of a small cylinder up to '15 Despite the miniature size, can boast high performance. Therefore, AAA batteries are widely used in a variety of children's toys.
3. "Finger". They are larger than the "mizinchikovye". Referred to as AA. It is also widely used in various household appliances.
4. "Crown". Have a rectangular shape, the two jacks and plug. Mainly used in radio communications.

What is the difference from the saline alkaline batteries

To better understand what is the difference between the two, will comparative table.

Parameter	saline	alkaline
Terms of Use.	Not withstand voltage surges and low temperatures.	Easily withstand drops and jumps.
Shelf life.	3 years.	5 years.
Scope.	Designed for equipment with low levels of consumption.	It can be used with high-power devices.

Choosing the appropriate battery depends on the device with which you are going to use it. This should be considered when purchasing batteries. Making the right choices will help manual.
