Is it better to have a dry battery or a lithium battery

Good safety performance Polymer lithium battery adopts aluminum-plastic flexible packaging in structure, which is different from the metal shell of liquid battery.

The thickness is small and can be made thinner Ordinary liquid lithium battery adopts the method of first customizing the shell and then plugging the positive and negative electrode materials, and there is a technical bottleneck in the thickness of the following, while the polymer cell does not have this problem, and the thickness can be less than 1mm, which is in line with the current demand direction of mobile phones.

Light weight The weight of polymer batteries is 40% lighter than steel-shell lithium batteries of the same capacity specification, and 20% lighter than aluminum shell batteries.

Large capacity polymer battery capacity is 10 15% higher than the same size of steel shell battery, 5 10% higher than aluminum shell battery, becoming the first choice for color screen mobile phones and MMS mobile phones, and most of the new color screen and MMS mobile phones on the market also use polymer cells.

The internal resistance of the polymer cell is smaller than that of the general liquid cell, and the internal resistance of the domestic polymer cell can even be below 35m, which greatly reduces the self-consumption of the battery, prolongs the standby time of the mobile phone, and can fully reach the level of international standards. This polymer lithium battery, which supports large discharge currents, is an ideal choice for remote control models and has become the most promising alternative to nickel-metal hydride batteries.

The shape can be customized Polymer batteries can increase or decrease the thickness of the battery cells according to the needs of customers, develop new cell models, which are cheap, have a short mold opening cycle, and some can even be tailored according to the shape of the mobile phone to make full use of the battery shell space and improve the battery capacity.

Good discharge characteristics Polymer batteries use a colloidal electrolyte, which has smooth discharge characteristics and a higher discharge platform than liquid electrolytes.

What battery is better for outdoor power supply, lithium iron phosphate batteries for outdoor mobile power banks in terms of performance: if they are all low-temperature special batteries, polymerization silver banquet lithium batteries are better than lithium iron phosphate batteries; If it is used at room temperature, the high-current discharge capacity polymer lithium battery is better than the lithium iron battery, but in terms of safety performance, the lithium iron battery is safer than the lithium battery. At the same time, high-temperature sex socks can be better than lithium iron batteries.

Summary. Hello dear, it's a pleasure to serve you. Lithium battery with the same capacity, for the same model of the same capacity of lithium battery, the weight of the weight is of course better than the light quality, the weight of the heavy means that the active ingredient of the battery is sufficient, the stored power must be more, and the light weight may be a false standard.

Good dear to you, very stupid, happy to serve you. Lithium battery with the same capacity, for the same model of the same capacity of lithium battery, the weight of the weight is of course better than the light quality, the weight of the battery indicates that the active ingredient of the battery is sufficient, the stored power is set more, and the light weight may be false.

In addition, it is necessary to consider the outer packaging of lithium battery rolling. Some lithium batteries have outer packaging. These outer packaging also occupy a certain amount of weight.

So when weighing your lithium battery into the chain acre row. Be sure to remove the outer packaging from above. Weigh the actual weight of the lithium battery.

Can you use a lithium battery with the same capacity that is twice as much in weight.

The weight difference is doubled. Indicates that there must be something wrong with that light battery. It is definitely usable, but it is not recommended.

I have clearly told you above. The weight difference is large, indicating that the light battery has a false standard. If you use it for a long time, it may cause damage to the battery.

Dry cell battery. Dry batteries, also known as voltaic batteries. It is made up of multiple sets of round boards that appear in pairs and are stacked in a certain order.

The inside can be either a paste-like substance or gelatin. This type of battery is a primary battery, which means that it cannot be recharged and used after discharge. This is also the biggest difference between dry batteries and lithium batteries.

The No. 5 and No. 7 batteries that we often see in wireless mice, alarm clocks, calculators, radios, etc. are dry batteries, and once they are used and run out of power, they will completely announce the end of their life.

Lithium battery. Compared with dry batteries, lithium batteries are secondary batteries, which are the kind of batteries that can continue to be charged and reused after the power is used up. The feature of recycling has become a watershed between secondary batteries and dry batteries.

Lithium batteries are generally divided into lithium-ion batteries and lithium polymer batteries, which are widely used in mobile phones, electric vehicles, small household appliances, notebooks, electric shavers, etc. It is more widely used than dry batteries.

Summary of the differences. Dry batteries are non-cyclic batteries, while lithium batteries are recyclic rechargeable batteries. It can be charged and used at any time.

Dry batteries generally contain heavy metals such as mercury and lead, because they are primary batteries, they will be discarded after use, which is easy to cause battery pollution. Whereas, lithium batteries are free of harmful metals.

The lithium battery itself has a fast charging function and a high cycle life, which is a height that dry batteries cannot reach. Moreover, in terms of safety, lithium batteries also have measures to protect the circuit.

Lithium battery rechargeable recyclable [expensive].

Dry battery is disposable and disposable for easy use [cheap].

In addition, from the top of the battery capacity density, lithium batteries are better.

Dry batteries belong to primary batteries in chemical power sources and are a type of disposable battery. Because the electrolyte of this chemical power device is a paste that cannot flow, it is called a dry battery, which is relative to a battery with a flowing electrolyte. Lithium battery is a type of battery that uses lithium metal or lithium alloy as the anode material and uses a non-aqueous electrolyte solution.

Lithium batteries for low-speed electric vehicles.

It must be a lithium battery that is good and has a long range, but at the same time it is more expensive. Before buying a lithium battery, see if the battery cell used is a product, the quality of the battery determines the quality of the battery, such as capacity and energy density, etc., and then find a lithium battery produced by a large manufacturer, the production process is mature, the after-sales service is guaranteed, and the lithium battery market reference price is 1250 yuan. If you need to run long distances, it is best to install a range extender, with which you are not afraid of running out of power halfway, it can help you gallop without worry.

Recommendations for the use of range extenders:

It is not recommended to start the range extender when the battery is full, and it is generally recommended to start it when the battery is only 30%-40%. There is no particularly good effect when starting when the battery is full, in order to be environmentally friendly, it is recommended to start the range extender when needed, battery pollution is more serious than exhaust gas pollution, and protecting the battery is to protect the environment. It is not recommended to use it when the battery is not a little charged, the range extender is electric when it starts, and it may not catch fire when the battery is not charged at all.

Dry batteries are generally lead-acid batteries.

With the same capacity and voltage, lead-acid batteries are 3 times heavier than lithium batteries.

Lead-acid batteries also have a short lifespan, and the current lead-acid batteries basically can't run far in two years, while lithium batteries can last for 5 years.

Due to its own weight, the battery life cannot be compared with lithium batteries.

But dry batteries** are cheaper.

It depends on how you choose. What's right for you is good.

Lithium battery electric vehicles:

Advantages: high efficiency. The body is light, the mileage is long, and the requirements for user use and maintenance are not strict.

Disadvantages: **High, domestic lithium battery technology is uneven, and lithium battery used in electric vehicles has potential safety hazards.

Lead-acid battery electric vehicles:

Advantages: cost-effective. The battery is relatively cheap, has a large capacity, many brands of batteries can be selected, and the technology is mature.

Disadvantages: Not efficient. The battery pack is bulky, resulting in the weight of the body, the driving range is short, and the battery needs to be maintained on schedule.

The differences between lithium batteries and dry batteries are as follows:

1. Lithium battery: the positive plate is ductile carbon, the negative electrode is a lithium-ion compound, there are currently two kinds, lithium cobalt oxide and lithium iron phosphate, and there are roughly two kinds of structures, one is winding type, and the other is laminated type.

2. Dry batteries are chemical batteries that generate direct current with paste-like electrolytes (wet batteries are chemical batteries that use liquid electrolytes), which are roughly divided into primary batteries and internal batteries, which are commonly used in daily life and lightweight batteries.

Lithium battery is a kind of battery that uses lithium metal or lithium alloy as positive and negative electrode materials and uses non-aqueous electrolyte solution. In 1912, lithium metal batteries were first proposed and studied. In the 70s of the 20th century, lithium-ion batteries were proposed and began to be studied.

Due to the very active chemical properties of lithium metal, the processing, storage and use of lithium metal have very high environmental requirements. With the development of science and technology, lithium batteries have become the mainstream.

Lithium batteries can be broadly divided into two categories: lithium metal batteries and lithium-ion batteries. Lithium-ion batteries do not contain lithium in a metallic state and are rechargeable.

The fifth-generation product of rechargeable batteries, lithium metal batteries, was born in 1996, and its safety, specific capacity, self-discharge rate and performance** ratio are better than those of lithium-ion batteries. Due to its own high technical requirements, only a few companies in a few countries produce this lithium metal battery.

Brand model: Nanfu battery.

System: No. 5 battery.

1. The principle is different: the carbon rod of the dry battery is the positive electrode, and the zinc cylinder is the negative electrode, which converts the chemical energy into electrical energy and supplies the external circuit. In chemical reactions, since zinc is more active than manganese, zinc loses electrons and is oxidized, while manganese gets electrons and is reduced.

The lithium battery adopts a spiral winding structure, and is made of a very fine and highly permeable polyethylene film separator car core material between the positive and negative electrodes.

2. Different materials: Dry battery is a voltaic battery, which uses a certain absorbent (such as sawdust or gelatin) to make the contents into a paste that will not spill out. Lithium batteries are batteries that use manganese dioxide as the cathode material, lithium metal as the anode material, and non-aqueous electrolyte solution.

3. Different uses: dry batteries are suitable for flashlights, semiconductor radios, tape recorders, cameras, electronic clocks, toys, etc., and are also suitable for national defense, scientific research, telecommunications, navigation, aviation, medicine and other fields in the national economy. Lithium batteries are widely used in mobile phones, laptops, power tools, Rang Zhao electric vehicles, street lamp backup power supply, navigation lights, and small household appliances.

The differences between dry batteries and lithium batteries are as follows:

1. Dry batteries are disposable batteries; Lithium battery is a rechargeable battery, which can be charged in multiple hail cycles, and has no memory, and does not need to be charged and used according to the amount of power.

2. Dry batteries are very polluting, many batteries used to contain heavy metals such as mercury and lead, which are seriously polluting to the environment, because they are disposable batteries, and they are quickly used up and thrown away, but lithium batteries do not contain harmful metals.

3. Lithium batteries also have a fast charging function, and the cycle life of Hunger Lu is also very high, which is beyond the reach of dry batteries, and now many lithium batteries will have protection circuits inside.

4. Lithium batteries can be recharged repeatedly, like mobile phones, the batteries in the camera are lithium batteries, and the dry batteries cannot be charged, as long as the electricity in the battery is used up, they can no longer be used, like the No. 5 and No. 7 batteries sold in the store are dry batteries.

The difference between dry batteries and lithium batteries is mainly in the raw materials for manufacturing and production, which creates the difference in their electrochemical properties.

In general, the electrochemical performance of lithium batteries is much better than that of dry batteries, but in terms of manufacturing costs, it is much more expensive. The main working principle of dry cell batteries is the redox reaction, which is realized in a closed loop.

It is very similar to the galvanic battery, which converts chemical energy into electrical energy. The common dry battery is a zinc-manganese battery, with a positive carbon rod between the middle cracks, a mixture of graphite and manganese dioxide, and a layer of fiber web.

between the ingredients

The net is coated with a thick electrolytic paste, which is composed of ammonia chloride solution and starch, and a small amount of preservative. The outermost layer is a cylinder made of metal zinc skin, which is the negative electrode. Dry batteries also become voltaic batteries, which are made up of multiple sets of round plates that appear in pairs and are stacked in a certain order.

There are two different metal plates on the round plate, and there is a layer of cloth between the layers that acts as a conductive force.

Dry batteries are very polluting, and many batteries used to contain heavy metals such as mercury and lead, which caused serious pollution to the environment. Because it is a disposable battery, it is quickly discarded when it runs out, but lithium batteries do not contain harmful metals. Lithium batteries also have a fast charging function, and the cycle life is also very high, which is beyond the reach of dry batteries, and now many lithium batteries will have protection circuits inside.
