What are the usages of batteries in daily life?

The battery has a positive negative this is installed correctly the main points of the battery.

The disposable dry cell

One-time zinc manganese alkaline battery, the battery is the national morality, many domestic brands, such as the most common "digititan, energizer, duracell GP super, peony" are zinc manganese dry battery production and sales.

The battery price is cheaper, and better power, long storage time and temperature to adapt to the condition is good, suitable for medium and small discharge current density.Defect is generally have a larger internal resistance, so the digital camera to use alkaline battery photo number is very little, battery discharging too rapidly, but the battery can still be normal use after a period of time.

Alkaline batteries are not suitable for as a digital camera driver power supply, this is because: LCD digital camera preview, image data processing, zoom lens, shoot takes a lot of power, which often leads to some users when using new alkaline batteries, take a few photos, appears low battery alarm or camera is helped by a cause.So, generally don't use the alkaline battery, although will not have any damage on the camera, but little practical significance after purchase

The common dry cell or zinc carbon batteries, zinc as the anode and cathode carbon and manganese dioxide active material, electrolyte consists of ammonium chloride, zinc chloride, starch and so on.At 25 ℃ can provide 1.5 V voltage value.The development of this kind of battery is quite early, about in 1862 by the French G.L echance invention.Although the development of the early, but because of cheap, easy manufacturing, low self-discharge rate, high energy weight ratio (50 ~ 80 wh/Kg) and the advantage of easy to carry,So in a battery, is still the highest yield and the most widely used one.

Although technology development for a long time, but still has the defects of power is too small, makes the battery does not apply to large current discharge;In addition, also has the problem of voltage instability in the process of discharge.Zinc manganese dry cell open circuit voltage will be for the duration of storage and the different natures of the cathode manganese dioxide (electrolytic manganese dioxide, natural manganese dioxide, etc.), could range between 1.50 ~ 1.80 V.If the use of electrolytic manganese dioxide, because of the high purity and activity, can promote the battery voltage and capacitance.

Zinc manganese dry cell preservation is very important, if placed in high temperature and wet environment, will make the zinc corrosion of anode and further cause serious self-discharge.In addition, zinc manganese dry cell sealing good degrees also very important;If poor sealing situation, the moisture in the electrolyte will evaporate, prevented the battery discharge, on the other hand may also occur because of oxygen into the battery self-discharge rate increase.

Dry cells use to apply tospecial, scientific research, drilling, communications, navigation,special, medical treatment, upper air and industrial and agricultural production, lighting, computers, television sets, tape recorders, cameras, electronic clock, electronic watch, such as power supply, become an important part in the national economy indispensable.

The battery is refers to the chemical energy or light energy into electrical energy device.Batteries are mainly chemical battery, solar cells andspecial battery.

The main purpose of the battery is:

(1) (') containing Battery electrolyte solution and the cup of the metal electrode to generate an electric current, groove or other containers or composite part of the container space.With the progress of science and technology, the battery refers to a small device can generate electricity.Such as solar cells.The main performance parameters of the battery are electromotive force, capacity, specific energy and resistance.

(2) use batteries as energy source and can get stable voltage, stable current, stable power supply for a long time, influenced by the outside world is very small current, and the cells of simple structure, easy to carry, easy to charge and discharge operation, not affected by weather and temperature, stable and reliable performance, in all aspects of modern social life play an important role and occupies a large proportion in the electricity use.

(3) alkaline batteries are manganese dioxide as positive pole, a cathode, zinc and potassium hydroxide as the electrolyte.Its features on the zinc carbon batteries to excellent, large capacitance, jinding alkaline batteries, for example, an average of 5 times more than carbon zinc battery power (power ratio in different electric products varies), save, leakage resistance, good temperature resistance, good voltage change is small, can get stable voltage, large power flow still can discharge with high efficiency, therefore the size of the current device is suitable for use.

(4) carbon zinc battery manganese dioxide as positive, a negative reaction, zinc chloride and zinc chloride aqueous solution as the electrolyte, the characteristic on voltage stability is bad, temperature characteristic is also poor, significant degradation under 0 ℃, for some of the requirements of voltage stability, small high output, high energy density of the electronic machine, carbon zinc battery is not applicable, only apply to the lamps and lanterns, lighting, toys, etc.

(5) alkaline batteries and carbon zinc batteries on the function of different is: zinc carbon batteries, alkaline batteries, electric capacity, small and large.High rate discharge, doesn't fit, suitable.Storage life, short storage life and kept for 2 years.Normal room temperature (21 degrees Celsius), the power loss of 15% a year.Long storage life, shelf life for five years.Normal room temperature, power loss in the first year by 5%, 2% a year later.Ultra-low temperature resistance is poor, 0 degrees Celsius, power loss quickly.Temperature tolerance, to 50 degrees to 20 degrees Celsius, are available.Use use narrow, only suitable for small current electric equipment, such as clock, water heater, etc.Large size current electrical appliances are applicable, current with electronic dictionaries, CD player.

(6) the chemical battery

Chemical battery, it is to point to by electrochemical reaction, the positive and negative active material of the chemical energy, the category of device into electrical energy.After a long period of research, development, a variety of chemical batteries, widely used.Big to a building in order to accommodate the huge device, small to millimeters.All the service of a better life for us.The development of modern electronic technology, puts forward high demands on chemical battery.Every chemical battery technology breakthrough, has brought the development of the electronic equipment revolutionary.The people of modern society, daily life every day, more and more inseparable from the chemical battery.Now many electrochemical scientists in the world, the focus in the field of as a chemical battery electric vehicle power.

(7) both dry and liquid battery

Dry and liquid battery are limited to distinguish between the early period of development.The earliest cells by glass containers filled with liquid electrolyte and two electrodes.Later introduced on the basis of the paste electrolyte battery, also known as dry cell.

(8) now there is still a "liquid" batteries.In general is very large volume of varieties.Such as those for uninterrupted power supply of large fixed type lead-acid battery or lead acid battery with solar cells.For mobile devices, and some use is fully sealed, maintenance-free lead-acid batteries, such batteries have been successfully used for many years, the sulfuric acid electrolyte is fixed by silica gel or the glass fiber separator suction.

(') containing Battery electrolyte solution and the cup of the metal electrode to generate an electric current, groove or other containers or composite part of the container space.With the progress of science and technology, the battery refers to a small device can generate electricity.Such as solar cells.The main performance parameters of the battery are electromotive force, capacity, specific energy and resistance.

Use battery as a power source, can get a stable voltage, stable current, stable power supply for a long time, influenced by the outside world is very small current, and the cells of simple structure, easy to carry, easy to charge and discharge operation, not affected by weather and temperature, stable and reliable performance, in all aspects of modern social life play an important role, occupies a large proportion in the electricity use.
