The difference between lithium battery and dry battery

The storage battery: lead dioxide is positive plate plate, negative plate is lead plate, through mutual insert structure, a layer of positive plate is the arrangement of a layer of negative plate, plate gap between those two, which filled with dilute sulfuric acid as electrolyte, to all of the positive plate connected to the anode, cathode all the negative plate connected with, the other general is 6 v and 12 v battery specifications, generally a lead-acid accumulator cell voltage is 2 v, 6 v and 12 v is actually three and six cells in series.

The lithium battery: positive plate is ductile, carbon anode is lithium ion compound, there are two, lithium cobalt oxide and lithium iron phosphate, structure roughly two kinds, one kind is coiling, is a kind of fold type, at present mainly coiling, is a layer of a layer of negative, positive plate insulation permeable ion diaphragm between them, and then roll together, into the encapsulation shell or bag;Fold type is the same shape of a layer of the anode anode layer, a layer of the diaphragm, a layer of the diaphragm such order stacked in the packaging.Lithium battery voltage is 3.6 V and 3.7 V.

Dry cell: the shell is zinc shell as the cathode, zinc shell inner wall with a layer of insulation through ion in the paper, and then fill the manganese dioxide, ammonium chloride and starch mixed paste, intermediate graphite conductive rods, then top with asphalt encapsulated, conductive rods buckle metal cap at the top lead to the anode. Dry cell's voltage is 1.5 V.

Dry cell is a kind of voltaic cell, using some kind of absorber, such as wood chips or gelatin) make inclusions not paste spillover.The power of the commonly used as a flashlight, lighting, radio, etc.Dry cell technology in China after years of development, its specific energy, cycle life, high and low temperature adaptability problems such as there has been a breakthrough.

Think tank research center of research data shows that at present our country is gradually narrowing the gap with international advanced technology, in part of the core technology has reached the international level, and increasingly into the international market.

Dry cell (Drycell) is a kind of paste electrolyte to produce direct current (dc) chemical batteries (wet cell is for the use of liquid electrolyte chemical battery), roughly divided into two kinds, a battery and secondary battery is for common use of daily life, as well as the portable battery.it

Homemade in the laboratory to the battery

Homemade in the laboratory to the battery

Can be used in many electrical appliances.

Common dry cell for zinc manganese battery (or zinc carbon batteries, namely dry Leclanche cell).

Dry cell belongs to the chemical power of the battery, is a kind of disposable batteries.Because this kind of chemical power source device the flow of electrolyte is a kind of can't paste, it is called a dry cell, this is relative to a flow of electrolyte battery.Dry cell is not only applicable to the flashlight, transistor radio, tape recorder, camera, electronic clock, toys and so on, and also forspecial, scientific research, telecommunications, navigation,special, medicine, etc. In all areas of the national economy, is very good.Ordinary dry-cell batteries are mostly zinc manganese battery, the middle one is the anode carbon rod, a mixture of graphite and manganese dioxide of outsourcing, the outside is a layer of fibres. Online electrolyte with very thick paste, its composition is the ammonium chloride solution and starch, and small amounts of preservatives. The outermost layer is made of metal zinc skin tube, which is negative, the battery discharge is the ammonium chloride and zinc electrolytic reaction, release the charge by graphite conductive to the anode carbon, zinc electrolysis reaction is will release hydrogen, this gas is may increase the risk of battery internal resistance, and mixed with graphite manganese dioxide is used to absorb hydrogen. But if the work or the battery is too long, manganese dioxide is too late or have had no ability to absorb nearly saturated, the battery will be lost due to internal resistance is too large, the output current is too small. But at the moment, if the battery heating, or place a period of time, its internal accumulation of hydrogen will heat release or slow release. Manganese dioxide by reduction to restore, also the battery was alive again!

With the development of science and technology, dry cell has developed into a big family, so far, already has more than 100.Common with ordinary zinc-manganese dioxide dry cell, alkaline zinc-manganese dioxide dry cell, magnesium, manganese dry batteries, zinc air battery, zinc oxide mercury batteries, zinc, silver oxide batteries, lithium manganese battery, etc.

For most used zinc-manganese dioxide dry cell, because of the different structure and can be divided into: paste zinc-manganese dioxide dry cell, paper plate zinc-manganese dioxide dry cell, diaphragm zinc-manganese dioxide dry cell, zinc chloride zinc manganese dry battery, alkaline zinc-manganese dioxide dry cell, quadrupole parallel zinc-manganese dioxide dry cell, laminated type zinc-manganese dioxide dry cell, etc.

1, according to the need to select the battery.For example: in the flash light, camera, MP4, electric toys need large current output apparatus, had better choose alkaline zinc manganese battery (L).Used in remote controls, watches, instruments of the general demand, choose ordinary zinc manganese battery (S, C, P).

2, pay attention to the performance of the battery price, do not blindly accepted western brands.In fact, many domestic brands battery performance and low cost are higher than similar foreign products.

3, pay attention to the storage life of the battery.Ordinary zinc manganese battery warranty for 2 years.Should choose when buying a new product.Alkaline zinc manganese batteries and the difference between ordinary zinc manganese battery alkaline batteries in the eyes of ordinary people points and ordinary zinc manganese battery two kinds.In the past, people in daily use was not ideal, the service life of the battery that is alkaline zinc manganese batteries and the difference between ordinary zinc manganese battery.In everyday use, flash light, camera, MP4, electric toys such as heavy traffic electric appliance can display the alkaline batteries and most common characteristics of zinc manganese battery.

Alkaline zinc manganese battery in flash frequency respectively for 144 times, camera film 8 volumes, toys to start the 183 minutes.The index of ordinary zinc manganese battery in use over the same period the average 6.86, 4.38, 3.81 times, and the price performance ratio 4.34, 2.78, 2.41 times.For consumers, using reasonable alkaline zinc manganese batteries can be at ease of use.

Dry cell belongs to the chemical power of the battery, is a kind of disposable batteries.Because this kind of chemical power source device the flow of electrolyte is a kind of can't paste, it is called a dry cell, this is relative to a flow of electrolyte battery.

Lithium battery is a kind of lithium metal or lithium alloy anode materials, the use of water battery electrolyte solution.First appear in the lithium battery from the great inventor Thomas Edison, use the following response:

Main difference is that the power supply reactive material is different, different features.

The battery there are basically points to charge (also called wet battery) and cannot charge (also called dry cell).Not charging the battery, give priority to with 5 batteries, known as the alkaline batteries.Better have a lithium ion batteries about 5 times, endurance is basically alkaline batteries, but the price is 5 times.Now with Panasonic and the eu lithium-ion battery as one of the best 5 non rechargeable batteries.Rechargeable batteries are divided into nickel cadmium battery, nickel metal hydride battery and lithium ion rechargeable batteries.With lithium ion rechargeable battery is best.Nickel cadmium battery is usually 5 size, the older, have been eliminated, but also sell outside.Nickel metal hydride batteries are usually the size of the 5, and now is the mainstream of rechargeable batteries, 5 to 2300 mAh to 2700 mAh for the mainstream.Lithium ion rechargeable batteries are usually the size of their own design.As to the life of rechargeable battery, lithium ion rechargeable battery is best, then the nickel metal hydride, and then the nickel cadmium.The advantages of lithium ion power can be kept in more than 90%, has been to the final almost 5% of the electricity, and then suddenly without electricity.And Ni-Mh batteries is to go all the way, has said that at first is 90%, then 80%, then 70%.The battery life can meet the high-end electronic products, power-hungry especially when digital camera to use flash light, need a long time to take one again, and lithium ion rechargeable batteries, there is no this problem.So if not 5 battery with the camera, will basically is manufacturer to design their own lithium-ion rechargeable batteries.This is the preferred.If is 5 batteries, you can buy nickel metal hydride rechargeable batteries, and then buy a good charger, it is best to first discharge in charge, will extend the battery life.Nickel metal hydride rechargeable batteries may now be GP, the eu, SONY, such as for good, homebred product also is pretty good.But the charger for SONY, because of the discharge function.

The batteries to environment pollution is severe, a battery can be dozens of cubic meters of water pollution.Some even said the waste battery life garbage disposal can cause damage, such as Japanese minamata disease section 5 waste batteries can make a square meters of land desolate.
