Next-generation graphene battery The phone is fully charged in five minutes

At the 2016 Mobile World Congress (MWC) Shanghai exhibition, the newly opened graphene exhibition area was extremely popular
.
The graphene exhibition area set up for the first time became a highlight, attracting well-known enterprises and experts such as Carbon Valley Group, Sixth Element and Nobel Prize winners in physics to participate in the exhibition with the latest products and technologies, including many innovative products derived from the characteristics of graphene, such as flexible mobile phones, fast-charging batteries, ultra-thin sensors, etc
.

At present, graphene mainly exists
in two forms: powder and film.
Graphene powder is mainly used in the field of new materials and energy fields, such as anti-corrosion coatings, heat dissipation materials, lithium-ion batteries, etc
.
Graphene film is used in electronics, environmental and pharmaceutical fields, such as touch screens, electronic components, etc
.

Ivan Buckley, project leader from the National Graphene Institute at the University of Manchester in the UK, said: "We have been almost non-stop for two days, and there is an endless
stream of people coming to inquire.
People are very curious about graphene, they may not understand the principle behind this material, but we will tell them that light bulbs made of graphene are more energy-efficient and can emit light for thousands of hours
continuously.
”

In the exhibition area of the University of Manchester, dimmable graphene bulbs were displayed, with filament-shaped LED lamps inside the bulbs, and the outer layer of the LED lamps was coated with graphene, which has strong conductivity and can reduce energy consumption
by 10%.
Buckley introduced: "Recently, the National Graphene Institute of the University of Manchester in the United Kingdom has developed a new graphene bulb, which has a stronger structure and lower price than LED bulbs, and a bulb may be about 10 pounds and can be used for a long time
.
”

Just when incandescent lamps are gradually replaced by LED bulbs, this new graphene bulb is about to bring another revolution
to lighting technology.
The National Graphene Institute at the University of Manchester in the United Kingdom began commercializing
graphene bulbs last year.
British Chancellor of the Exchequer John Osborne also praised the project
.
This new graphene bulb is still based on LED technology, which greatly enhances its performance and longevity
through magical graphene molecules.

Graphene with different molecular structures can provide raw materials
for downstream products for different uses.
The reporter saw that the booth of China Carbon Valley displayed graphene molecules with different morphological structures, including PE fiber, polyamide fiber, anti-corrosion coatings, lithium-ion batteries, separation composite materials and catalytic materials
.
Dai Jialong, chief scientist of China Carbon Valley, said: "According to the needs of the structure, it can be matched
to downstream producers.
For example, anti-corrosion coatings, which are being applied by the National Institute of Oceanography, can make the hull rust-free for at least 20 years
.
Another example is graphene-modified lithium-ion batteries, which can achieve fast charging
.
After sponge plus graphene, oil-water separation can be achieved, and graphene can also become a raw material for 3D printing, which is also being used
by the National Nano Center.
”

According to Dai Jialong, the trend of complete docking of the upstream and downstream industrial chain of graphene has just emerged, although the current industrial application is still rare, and the products are almost nothing, but the future business prospects are considerable
.

The ZapGocharger charger from Oxford uses a graphene lithium-ion battery, which can achieve a fast charge
of 5 minutes.
In 2013, the company received funding from the UK government and changed its name from "London Graphene" to ZapGoCharger
.
The company obtained a patent authorization for graphene battery technology from the Department of Materials Science of the University of Oxford and began to conduct research and commercial applications
of new energy batteries.
Simon Harris, investment director at ZapGoCharger, said: "Our ultimate goal is to be able to make graphene lithium-ion batteries into mobile phones, so we are going to start talking to companies like Huawei in China, but this may be four or five years from now, and now our technology is not mature
enough.
" ”

At present, the battery 5 minutes fast charge is only enough for 10% of an iPhone, the company has a clear 5th generation product plan, so that the third generation, can basically meet the 5
minutes of charging a mobile phone.

A Chinese investor in ZapGoCharger said: "We entered the company very early, and if the technology develops quickly, mass production
will be achieved in the next six months to a year.
" We are still very confident in the
graphene industry.
”

The products at the Graphene Centre at the University of Cambridge are even cooler
.
They applied graphene ink to cardboard paper to make a band on paper that people could play
by tapping their fingers on the pattern of instruments on the paper.
Its principle is through the characteristics of graphene ink environmental protection and high conductivity, which is used in water-based ink printing electronic products
.
Dr Stephen Hodge, a researcher at the Graphene Research Centre at the University of Cambridge, said: "This new method is a big step
forward in achieving mass production of highly conductive graphene inks on the market and creating competitive prices.
Cambridge Graphene is selling these new inks to build business with customers while offering inks and development solutions
to customers.
It is revealed that the graphene environmentally friendly ink has applied for a patent
.

The reporter also saw the flexible display bracelet
displayed at the Barcelona Mobile Communication Exhibition in February this year in the graphene exhibition area.
FlexEnable showcased a variety of flexible displays
that can be bent.
Simon Jones, Commercial Director of FlexEnable, said: "We offer a variety of technical possibilities, but ultimately it depends on customer demand for the product, and we are also working with some electronics manufacturers to hope to use it in different electronic products in
the future.
”

Just two months ago, a company in Chongqing called Moxi Technology announced that it was about to release a bendable bracelet-shaped smartphone, which means that the competition for flexible screen technology has risen to a new level
.
When the phone is rolled into a bracelet, its touch screen still works, and you can also unfold the phone into a rectangle, just like a normal smartphone, but this phone is thinner and longer
than a regular phone.

Yu Chongsheng, head of Moxi Technology Application Center, said: "The bendable smartphone products that will be mass-produced can only display black and white, and the color version prototype has been launched, and mass production is expected to be available
in 2018.
Technically, black and white is much
easier than color.
In this regard, FlexEnable's Jones said: "We are looking forward to seeing the launch of Moxi's flexible screen mobile phone, which will also prove more uses and functions
of graphene.
" ”

Nobel laureate Konstantin Novoselov of the University of Manchester also appeared in the graphene exhibition area
.
For the current application value of graphene, Novoselov said: "Graphene technology should be applied, more applications should be explored in two-dimensional materials, and RFID (radio frequency identification) sensors should be combined to develop and manufacture multifunctional products
on these foundations.
