If you want to buy lithium batteries, do you have any recommendations?
In fact, lithium batteries are very common. It is relatively easy to assemble a lithium battery (PAIKE) (the investment is low). If you build a fuel cell, the investment will be relatively large.
Do you have any recommendations for AA lithium batteries?Lithium batteries are new energy sources that are environmentally friendly, small in size and light in weight. As long as they are produced according to standards, the quality is good.
What is the difference between lithium batteries and 3 cell lithium batteries?Laptop batteries are filled with lithium batteries that are slightly longer and larger than common AA rechargeable batteries. This type of lithium battery is called a “battery”. cell" ". For example, a “4-cell battery” means a group of 4 cells connected en series, then 2 groups connected in parallel; a “6-cell battery” means a group of 3 cells connected in series, then 2 groups connected; in parallel. But I can't say exactly how to combine the "3 hearts".
The description of the battery configuration that you mentioned is mainly because the editor of the relevant website is not clear about the number of "cells" of the battery of the laptop, so it only shows lithium batteries.
Moreover, since a single-cell lithium battery has a voltage of about 3.6 V and a current of 2400 Ma, only a small batch of inexpensive machines now use this relatively limited number of “basic” batteries. lasts 1 hour, very poor performance. Therefore, try not to choose a machine with a relatively small number of “cellular” batteries.
In the same way, some machines present themselves as "vei"ultra long", but they are actually equipped with a "9 cell battery". The importance of the number of cells is obvious.
What is the difference between a 15400 lithium battery and an 18650 lithium battery ?18650 is the battery specification There is 3.6V lithium battery and 1.2V No. 5 nickel metal hydride battery is the common rechargeable specification. -1.2V metal hydride. There are also 3.6V lithium ion battery and 3V lithium iron battery
What is the difference between 18490 lithium battery and 18490 lithium battery? 18650 lithium batteryThe main difference between 18490 lithium battery and 18650 lithium battery is size and capacity
1. We don't talk about voltage, because if the same material. is used, the tension will be the same and different materials will have different tensions
2. The first 18 is the diam.be of the battery, which is the same.
3. 490 refers to 49mm and 650 refers to 65mm. This may be a simpler understanding.
4. The 18650 lithium battery is larger than the 18490 lithium battery.
5. Under the same material conditions, the battery capacity will be larger if it is bigger.
Extension: I have hardly ever heard of 18490 lithium batteries. The standard in the market is 18500 lithium batteries, such as IFR18500E600.
I hope Dianchizhidu's answer can help you.
What is the difference between a 3 cell lithium battery and a lithium battery?
Question: Enthusiastic netizens are satisfied with the answer: Lithium batteryThis is a type of battery. There are many types of batteries, including alkaline lithium, nickel-cadmium, nickel-metal hydride, lead-ac dry cells.ide, silver oxide and zinc-manganese. Most laptops use lithium batteries. 3 cell means that the laptop battery contains several small lithium batteries (just like several dry cells used in a flashlight). N core means N batteries are connected in parallel. Laptop battery voltage is basically around 11V, which is universal. The same battery, so the more cells connected in parallel, the greater the capacity and the longer the battery life. And the capacity is proportional to the number. Ordinary home users are recommended to use the number of cores that come standard with their computers, such as 3-cell lithium batteries, because they are mainly used at home and have a stable power supply. Ordinary office users recommend usingUse 6 and 8 cell lithium batteries because the standby time is relatively long, making your office more convenient. If you have high mobile office needs, you can consider 9 and 12 cell lithium batteries. These batteries are too heavy to carry and are not as stable as 6 and 8 cell batteries.

What is the difference between a 3-cell lithium battery and a 6-cell lithium battery?The difference between 3 and 6 cell batteries is that
One battery contains 3 batteries, which can be around 11.1V 2.2Ah due to different manufacturers.
The 6-cell type contains 6 batteries and the model is approximately 11.1 V4.4 Ah. It is generally used in laptops
The power of laptops is generally above 65W. /p>
In this way, the standby time of 6 cores is twicelonger than that of the 3 cores. Of course, the price is also more expensive.
It's very simple. The 3-cell one has 3 cells (there are 3 batteries inside), and the 6-cell one has 6 cells. From the quantity, it is not difficult to understand that the 6-core one is significantly more expensive than the three-core one. The standby time is also more than doubled
What is the impact of connecting 3V lithium batteries and 4V lithium batteries in seriesThe maximum and minimum limit voltages of different types of batteries lithium are different?
For example, some simple lithium batteries can be discharged to a minimum of around 2.9 V.
Regardless of the type of lithium battery, it is best to Do not charge it when the battery voltage reaches the lowest level.
The best method of charging is: if conditions permit; as long as the battery is discharged The recCharging immediately is the best way to extend battery life.
What is the difference between power lithium batteries and ordinary lithium batteries?There are the following differences between power lithium batteries and ordinary lithium batteries:
1. Different properties.
Power lithium batteries refer to batteries that provide power to transportation vehicles, generally compared to small batteries that provide power to portable electronic devices; Ordinary lithium batteries are made from lithium metal or lithium alloy. Aqueous electrolyte solutions as negative electrode materials are different from rechargeable batteries, lithium-ion batteries and polymer lithium-ion batteries.
2. The battery capacity is different.
When all the batteries arehave new ones, use a discharge meter to test the battery capacity. Generally, the capacity of lithium batteries is about 1000-1500 mAh, while that of ordinary lithium batteries. The battery capacity is more than 2000 mAh, and some can reach 3400 mAh.
3. The discharge power is different.
A lithium battery with a power of 4200 mAh can discharge in just a few minutes, but ordinary lithium batteries cannot do this at all. Therefore, the discharge capacity of ordinary lithium batteries cannot be compared with that of power lithium batteries. . The biggest difference between power lithium batteries and ordinary lithium batteries is their large discharge power and high specific energy. Since power lithium batteries are mainly used to power vehiclesicles in energy, they must have a higher discharge power than ordinary batteries.
4. Different applications
Batteries that provide motive power for electric vehicles are called lithium power batteries, including traditional lead-acid batteries, nickel-hydride batteries metal and emerging lithium-ion batteries. Power batteries. Lithium batteries are divided into power batteries (hybrid vehicles) and energy batteries (pure electric vehicles). Lithium batteries used in consumer electronics such as cell phones and laptops are generally called lithium batteries to distinguish them from those used in electric vehicles. Powered by lithium battery.
Lithium batteries are a type of battery that uses lithium metal or lithium alloy as material.with a negative electrode and uses a non-aqueous electrolyte solution.
Lithium metal batteries were first proposed and studied by Gilbert N. Lewis in 1912. In the 1970s, M. S. Whittingham proposed and began studying lithium-ion batteries. Since the chemical properties of lithium metal are very active, the processing, storage and use of lithium metal are subject to very high environmental requirements. Therefore, lithium batteries have not been used for a long time. With the development of science and technology, lithium batteries have now become mainstream.

Electric vehicles Evolution is fundamentalentally obvious to all our friends, and automotive editors can only say that the prospects are infinitely good. So what do friends know about electric vehicles? For electric vehicles, it is more important to be environmentally friendly and save money than other new energy vehicle models, because electric vehicles can reduce fuel price. Then you can't afford to buy batteries for new energy vehicles. Today, let's share it with our friends.
New energy vehicle batteries cannot be replaced: current situation
According to various websites such as Lithium Battery Network, the current production cost of power batteries is 1,300 yuan/kWh, and the vehicle installation price is 1,700 yuan! Why is there this 400 yuan price difference? The price that the manufacturer sells to the ch companyThe money is: production cost + gross profit of the product. In 2016, the supply of automobile batteries was fundamentally insufficient and the gross profit margin of the products was high. Personally, I think that the gross profit of electric battery manufacturers will definitely be 30%. Otherwise, why would manufacturers launch battery projects? I think the price difference of 400 yuan is just the battery manufacturer's gross profit!
The current battery replacement price of BYD Tang: Looking at the quotation, the battery replacement price of Tang is more than 50,000 yuan. The price of Tang's 18.5 degree battery is calculated based on the price of the surface mounted vehicle. of 1700*18.5 = 31,405 yuan, why is the quote for battery replacement of 30,000 batteries 50,000 or 60,000? In principle, everyone knows that automobile parts have a so-called zero ratio, most of which are 300%. Why is there a zero ratio? Even the automotive aftermarket sector has to make money. Although auto parts have an average zero ratio, the more expensive the parts, the lower the zero ratio. Batteries are high-value components, and the zero ratio should be around 200%, or even less. Based on Tang's replacement of 55,000 batteries, I think the battery zero ratio is 50,000/31,405 = 160%, which is considered a conscientious zero ratio among auto parts.
New energy vehicle batteries cannot be replaced: lithium-ion batteries
As a new type of high-voltage, high-energy-density rechargeable battery, Secondary lithium-ion batteries have unique characteristics. physical and electrical characteristics. Chemical properties, has broad application prospects in civil fieldsls and defense. Its outstanding characteristics are: light weight, large energy storage, no pollution, no memory effect and long service life. With the same volume and weight, the storage capacity of lithium batteries is 1.6 times that of nickel-metal hydride batteries., is 4 times that of nickel-cadmium batteries, but man n uses only 20 to 30% of its theoretical development capacity, the development prospects are therefore very promising. At the same time, it is a truly green battery that does not pollute the environment and is the best battery currently available for electric vehicles. Since the 1990s, China began to develop and use lithium-ion batteries, made breakthrough progress, and developed lithium-ion batteries with independent intellectual property rights.
I can't afford to buy batteries fornew energy vehicles. The automotive editor shared two batteries with its friends, namely Wei Chao, Tianneng and Sail. These three battery brands are basically all famous, but friends may be more familiar with Wei Chao, which is also the result of Wei Chao brand often appearing in our field of vision. So friends, after reading the sharing of automobile series, what do you know?
