Joining production needs to make sure that the lithium battery league charge is not practical. General assemble processing of power lithium battery pack only need to purchase related equipment and testing instrument, and then you can assembly lithium battery by yourself. Technology is relatively easy, and many electric vehicles are made of lithium-ion batteries. At present, a lot of training technical sales equipment manufacturers need to buy equipment, and there is no charge of the league.
You refer to the lithium battery electric vehicle expenses? Countries have to check out, and released, there are several was found out, the advantages of lithium battery technology itself is already mature many, also in popularity.
To be honest, don't join the league.
This kind of joining or the nature of the investment should be lithium battery PACK or the nature of the assembly, because the threshold is low, less input devices, as long as the simple case series parallel, easy to learn.
But, we in Shenzhen, Dongguan and other places that is, do lithium battery assembly, PACK, small and medium-sized, large-scale manufacturers, are a dime a dozen, there are a lot of manufacturers business are relatively weak. And you this simple mill processing plant, production, quality, management system is not sound, and lithium batteries belong to dangerous goods, the sales prospects is still not known, the second is if there is a safety accident, would be much trouble.
Furthermore, the perspective-taking, if it's good to sales, they have the equipment, why not recruit sewing worker directly one-stop production and sales, to master all the profits, why outbound?
From the point of these merchants to join the company's propaganda, is a scam, no doubt, should be based on its league, low-cost equipment high fees and selling inferior raw materials to cheat money. For the following reasons:
1) propaganda boasts a group of 48 v / 12 ah lithium-ion battery pack can have 300-500 yuan of profits, this is not possible, to the ex-factory price of 48 v / 12 ah now day is only less than 600, factory mass production is impossible to have such a high profit, manual mill production how can have such a high profit, if really have such high profits, these manufacturers why China merchants to join their recruits to mass production wouldn't it be better to make money by yourself?
2) lithium battery production now have mandatory national standards requirements, the production process and test requirement is high, the ministry of commerce and industry may be door-to-door sampling the product quality, mill type production is unable to guarantee the quality of products, there is the risk of the ministry of commerce and industry to ban.
3) Lithium batteries belong to dangerous goods, if mishandled, during the processing and storage is easy to produce the problem such as explosion combustion, then lose everything, can also cause casualties.
4) now whether electric bicycle, electric tricycle lithium-ion batteries, lithium-ion batteries or rechargeable batteries, treasure in the pearl river delta region at least nearly thousand small and large manufacturers, a glut on the market belongs to the basic situation, the competition is fierce, there is no joining publicity materials written vast demand.
5) if the joining process, manufacturers require you to make a initial equipment fees cost to each other's private accounts (account name not company name but personal name, even if the other side of the legal person or the names of the chief financial officer), the basic belong to the nature of fraud.
Full of Dongguan electronic technology co., LTD., with strong development strength and mature experience, using imported cylindrical 18650 lithium batteries, also is the demand for more and more customers with safe and reliable battery solutions.

What is the most fire graphene products nearly two years? Underwear, mask, and black gold batteries, Graphene battery, in particular, that black gold batteries, it don't of the fire. Recently small make up again see a graphene lithium battery project ready to put into production, and is not usually big capacity, is a 1.5 billion - watt! Today small make up through this message to everyone about graphene battery behind those cut constantly, is controversial.
1, graphene is what?
Now let's look at what is graphene. In 2004, the British game of the university of Manchester and carbon stripping out the graphene from graphite flake, the two of them therefore won the Nobel Prize in physics in 2010.Graphene, here is composed of single layer of carbon atoms honeycomb lattice two-dimensional atomic crystal, theoretical thickness of only 0.34 nm, its excellent electrical, thermal conduction, barrier property, such as material properties, so its application is a lot of people in the field of battery, is called the king of the "materials".
Academia has had a common view for graphene, namely the high cost of manufacture of graphene and technology is not perfect, if you want to achieve industrial application is still a lot of difficulties. Even now there are companies claim that there are new graphene products appeared, graphene in this kind of product also is more the role of additives, the batteries are no exception.
Solid-state ion learning team leader huang, institute of physics, Chinese academy of sciences, says professor now add a small amount of graphene in the anode can increase the positive electron conductance ratio and improve the battery discharge characteristics, but generally add less than one percent, can't say that with a bit of graphene lithium ion batteries becomes a graphene batteries.
What's more, the current graphene batteries were simply added some called multilayer graphene layers of graphite piece of composition. Theoretically speaking, single-layer graphene conductivity, best used for battery charging time is short, and the layer number of the more conductive the worse, the longer for the battery. There's almost no enterprise can claim to be using single-layer graphene made battery, more just using a mixture of graphene, specifically, contain a small amount of graphene composition of tiny multi-layer graphite.
Are some rigorous research institutions also dare not easily when authority papers published on graphene batteries. In the middle of December, 2015, the Chinese academy of sciences Shanghai silicate research team at the head of the science articles, points out that it developed a high-performance super capacitor electrode materials, some media praised: "the material has excellent electrochemical energy storage characteristics, can be used as a 'super battery electric vehicle, the highlight of the battery is charging 7 minutes, 35 kilometers. "Then graphene battery concept is quick.
But the message is given on the official website of Shanghai silicate by: "huang, a researcher at the Chinese academy of sciences Shanghai institute of silicate, rich and strong (powerful) led the research team with the Beijing university, researchers at the university of Pennsylvania, an ordered mesoporous synthesized (hole) in the less carbon layer of new material." And the journal science, this paper also made no mention of graphene, but carbon materials.
In academic circles, it seems, are hyped graphene cells is a false concept, rhetorics of graphene battery does not exist at present. Layout graphene has dozens of listed companies in China power battery field, but really can get almost no mass production machine products. It is within the scope of the world, can now mass production of graphene and no battery.
Now a lot of hype the concept of its stunt has significance than the practical value. Graphene material itself has high specific surface area and other properties of nano materials and current lithium ion battery industry technical system is not compatible, so the application of hope is very slim. This, the current applications of graphene in battery, the mainly is combined with silicon battery cathode inside instead of the original graphite, so they can absorb more than charged, improve the conductivity of the battery, reduce the resistance of the charge and discharge, performance improvement effect is limited. In fact, in the field of new energy battery, battery graphene so-called disruptive theory has never been in the industry recognition. Although graphene can be conductive agent, promote the fast charge lithium battery, can improve the rate performance in theory, but if the dispersion process does not reach the designated position, uneven mixing, is still hard work.
According to the current development situation, the new type flexible batteries, devices, display, catalysts, graphene could be promising. But in terms of storage battery, do not look good.
2, graphene is too expensive, even made the batteries, ordinary people also can't afford to consumption
Used in lithium batteries, graphene is mainly plays the role of, is a conductive agent, the two is likely to do embedded lithium electrode materials. In fact, these two points, are compete with traditional conductive carbon/graphite." Then the problem is coming, do you know the conductive carbon/graphite how cheap? Are sold by tons, sold by grams of graphene which day can to this price? Now lithium-ion batteries use a variety of materials, are all about a ton of tens of thousands, hundreds of things, and every day under price pressure, using graphene completely unrealistic." This is primarily a graphene is too expensive. A gram of thousands of prices, this is not a general enterprise to bear. And a couple of years ago, the price of graphene was as high as 5000 yuan per gram, far more than the price of gold. In addition, this is made out batteries, consumer also unbearable.
Recently, there is a market analysts said that at present our country graphene products and efficient battery project has formed a complete industrial chain, in fact, the current our country graphene materials are now in a critical period, from the laboratory to industrialization of the production technology is not high, the maturity of industrialization application of long path and other factors, graphene mass production has not yet been fully realized. Somebody thinks, this process is not implemented, they said our graphene battery can realize large-scale industrialized production is totally insane.
As a result, some lucid and industry insiders think, said China was born the graphene battery, too.
