What is black gold battery?

As we all know that black gold battery, namely graphene battery, spread out on battery industry after the exhibition in March 2016 in Tianjin.

At that time, a few industry giants have launched their own black gold series, in China's battery enterprises graphene applications, give a person walking in the forefront of the industry an illusion.

Then announced several enterprises have developed their own graphene products, high-profile graphene to join the club!

Small make up again see a graphene recently the lithium battery project ready to put into production, and is not usually big capacity, is a 1.5 billion - watt! At that time, small make up smile!

Graphene is what? What is black? Small make up today about the graphene batteries through the message to you talk about the cut constantly, Richard also story behind.

1, graphene is what?

Thirteen years ago, in 2004, two professors at the university of Manchester, England, geim and carbon stripping out the graphene from graphite flake, consisting of a single layer of carbon atoms honeycomb lattice two-dimensional atomic crystal.

This single crystals, is a kind of thickness of only 0.34 nm, with excellent electrical, thermal conduction, barrier property, such as the performance of new materials, has been sent to the infinite hope.

Has even been called the "king of the material", because its price than gold, and many people call it "black gold"!

While China's graphene research relative to the west, is lagging behind. Straight in December 2015, the Chinese academy of sciences Shanghai silicate is in the journal science by post that your related team recently developed a high-performance super capacitor electrode!

Remember, this is just the results of laboratory.

"According to its official website gives Shanghai silicate research institute, Chinese academy of sciences...Synthesized by an ordered mesoporous (hole) in the less carbon layer of new material." And in the journal science, this paper also made no mention of graphene, but carbon materials.

2, what is the graphene battery?

Then this new material was born, some media started to innuendo, extremely use up hype!

This be considered a "excellent electrochemical energy storage properties, can be used for electric vehicles' super battery of new materials, once used in batteries, will bring new breakthrough to battery behavior. It may even be "charge 7 minutes, 35 km."

Some thought that this concept is eager to get breakthrough in the technology of battery used by the enterprise. Then the concept of graphene battery was used by some people, just didn't think, just three months later, is show in Tianjin.

If high-performance graphene battery production comes out, and get the application, can bring great convenience for people's production and life, we have to for Chinese companies moved by a strong research and development and manufacturing capability.

3, actually have graphene battery?

However, China's enterprises large-scale application of graphene in battery, really true?It really like what?

We noticed a detail, in order to avoid future passive, hyped on oral graphene at the same time, these claims from already mastered the graphene production technology and application of large-scale market, on paper, try to use "graphene" therefore, "black gold"!

In unknown, however, as a industry media rounds after impact, the industry is clear, the enterprise's black gold batteries, graphene is in fact the battery! And the batteries in all aspects are better than normal ones.

But there are a few people know, until now, no matter domestic or foreign, graphene production of raw materials, on the technology is not perfect, have not yet fully entered the stage of industrialization, the manufacturing cost is too high, in the aspect of industrial application has not been promoted!

Although there are some industry claims that their products are "graphene" or "black gold" attribute, even released from already have "graphene" or "black gold" of the related products come out!

But from the point of the status quo of graphene, this kind of product is basically concept. If rose to the aspect of law, this product is fake, and the propaganda is false advertising!

Graphene application in the field of battery is also this kind of situation!

4, academic knowledge of graphene battery

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 electronic conductivity of the anode to improve discharge ratio characteristics of the battery.

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.

It was revealed that the graphene batteries were simply added some called multilayer graphene layers of graphite piece of composition.

And the reality is, there's almost no enterprise can claim to be using single-layer graphene made battery, use more is a mixture of graphene. Specifically, it contains a small amount of graphene composition of tiny multi-layer graphite.

And even if the graphene can be conductive agent, promote the fast charge batteries, can improve the rate performance in theory, but if the spread process does not reach the designated position, uneven mixing, still works hard.

If add an even less than one percent in the anode of graphene graphene batteries battery, you add a little bit of beef Fried radish and seasoning powder, then this is Fried radish can call beef radish?

At present, in any rigorous research institutions or academic journal, also cannot find on graphene battery.

In academic circles, it seems, are hyped graphene cells is a false concept, the current brand ink ENE battery does not exist. Graphene related some subversive theory has never been in the industry recognition.

5, graphene is too expensive, even made the batteries, ordinary people also can't afford to consumption

Used in battery, main play the role of graphene, 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."

So the question comes, do you know how cheap conductive carbon/graphite? Are sold by g! Otherwise known as black gold?

Speak a little bit ugly, even if the battery out, who can consumption have excuse me? Especially big battery price war, even as Grosvenor LTD handsome black gold battery, the price is also a dive!

Please remember, graphene far more than the price of gold.

6, graphene battery is really like

In fact, as soon as in graphene, has the media revealed that the battery is only increased the plate of the weight of batteries.

Has even been pointed out that at present on market 12 when Ann and 20 ampere hour black gold batteries, actually just 14 and 22 when Ann when batteries.

Seeking truth from facts, the graphene products and efficient battery project currently has not formed a complete industrial chain.

As a matter of fact, the current our country graphene material is in the stage from the key of research and breakthrough, production technology is mature, rapid industrialization application is still a long way to go.

If someone says your graphene battery or the battery is not gold, really not 14 or 22 PuPin, then, will you please take out your purchase by most of graphene can!

How much did you produce black gold battery? how much did you buy raw materials, you bought these raw materials from which production enterprises, the company is doing, let everybody see don't understand!

Black gold exactly how many dealers pit, it is estimated that up to now still not come out. On the Internet, however, for black out, since the batteries in black gold, seem to never stop!

If you used to hype, be reversed transmission or threaten by the market, the public won't pursue furthur. Actually more people still want battery industry of China to go ahead.
