Huawei announces new technology for Li-ion batteries
Watt Laboratory is an organization under Huawei's Central Research Institute. The company took part in the 57th Battery Symposium in Japan and made a curious announcement today.
Watt Laboratory unveiled the first graphene-assisted Li-ion battery. Graphene is a carbon material with a thickness of one atom, in which individual atoms are arranged in a honeycomb shape. The material is about 100 times stronger than the strongest steel and has great properties, when it comes to conducting heat and electricity. Therefore, graphene makes an excellent heat shield.
This is also its application in Huawei's new battery. The power pack unveiled by Watt Laboratory can withstand up to 60°C, which is 10°C higher than the currently existing upper limit. According to its creators, the graphene-assisted Li-ion power pack should have a battery life that's two times longer than that of a regular Li-ion battery with the same capacity.
Dr. Yangxing Li, Chief Scientist at Watt Laboratory, also mentioned some tests and their respective results.
For comparison, most Li-ion batteries degrade rapidly after two to three years, no matter if they're used or not. And high-temperature conditions make them age even faster. If the numbers quoted above are correct, Huawei's graphene-assissted battery should withstand 60°C temperatures for over 4 years before dying completely.
The new type of battery will not be making it into commercial handsets just yet. But another technology by Huawei will be getting its debut late this month. Namely, a super-quick charging Li-ion battery unveiled at the same symposium last year. We're certainly curious to see just how quick it will be.

Huawei is the 15th largest patent applicant in the world, and number one largest user of WIPO-PCT facility.
It's a bold move to venture into Li-ion, here Huawei has to go against dominance of big three: LG Chemical, Panasonic and Samsung SDI. Good luck to Huawei guys!

China taking graphene to the mass market by making it with ... corn
By Carlton Reid
Thursday, May 18th 2017 at 10:05AM BST
Chinese scientists have started to manufacture graphene from corn, they announced at a press conference held at Heilongjiang University on Friday.
This breakthrough means that graphene could now be made more cheaply, greatly expanding the supply of the material which has until now remained relatively small, reports China's Global Times.
Previously, the main source of graphene was graphite.
There are plenty of strong claims made for the use of graphene in the bike industry but, to date, only Vittoria, Catlike and Dassi have graphene-linked products on the market.
Catlike uses graphene in its high-end Mixino helmet. Vittoria’s 2017 tyre range majors on the inclusion of graphene in its list of ingredients. Vittoria claims that adding a one-atom-thick layer of graphene allows its tyres to remain hard on the straights but soften during braking or cornering. The Graphene+ tyres are also longer-lasting and more puncture resistant, says the Italian company, and they dissipate heat more efficiently.
Graphene was first isolated at Manchester University, and the city of Manchester aims to capitalise on its connection with the [URL='http://www.bikebiz.com/index.php/news/read/graphene-born-in-manchester-and-taking-on-the-world/020131']National Graphene Institute which is based in a futuristic new building just off Oxford Road, one of Manchester’s key thoroughfares, and which is currently being dug up for the installation of protected cycleways.[/URL]
The material was isolated – using Sellotape – by two Manchester University physicists, Andre Geim and Kostya Novoselov: winning them the 2010 Nobel prize for physics (and knighthoods). “Usually when you make materials thinner and thinner, their properties deteriorate,” said Sir Andre. “But with graphene we found things only got better.”
Graphene been hailed as the strongest and most conductive material in the world, with a huge range of electronic and medical appplications.
Sporting goods companies were among the first to make graphene-enhanced products – aside from bike frames and tyres, there are graphene-enriched tennis rackets from Head.
Graphene has a tensile strength of 130 gigapascals (Gpa), and, on a molecular level, is claimed to be the strongest known material in the world, 2000 percent stronger the toughest carbon fibre (Toray T1000 has a tensile strength of 6.3 GPa) and nearly percent stronger than diamond.
While we’ll never see a full frame made from graphene, it’s likely we’ll see more wheels and wheel brake tracks using the material, specifically because of its heat-dissipation properties.
Graphene is also a superlative electrical conductor and could be used to in electronic drivetrains, power meters, computers, and lights.
Vittoria has been working with graphene for nearly six years, in association with Directa Plus, a graphene factory. Directa Plus supplies graphene to Vittoria as three-to-seven-atoms thick “nano-platelets”.
A Qurano wheel made with graphene, says Vittoria, has 50 percent more lateral stiffness, 10 percent better heat dissipation, 18 percent more impact strength and yet is 15 percent lighter. Vittoria is an investor in Directa Plu, which was founded in 2005 and is based in Italy.
China has invested £3m in the National Graphene Institute via a five-year research partnership with the Beijing Institute of Aeronautical Materials.

China set to revolutionize graphene market with corn production technique
2017-05-18 09:33
Global Times Editor: Li Yan
Chinese scientists have become the first to manufacture graphene from corn, they announced at a press conference held at Heilongjiang University, Northeast China's Heilongjiang Province, on Friday.
Graphene is a rare type of carbon that has found practical applications in the semiconductor, electronics and battery industries. The super-light material is 200 times stronger than steel, an excellent conductor of heat and electricity and nearly transparent.
This breakthrough means that scientists will now be able to produce graphene more cheaply, greatly expanding the supply of the material which has until now remained relatively small.
Previously, the main source of graphene was graphite, another carbon variant that is often used in pencils. Fu Honggang, deputy dean at the School of Chemistry and Materials Sciences of Heilongjiang University began research into biological sources of graphene to chip away the expense and enormous pollution of traditional production methods.
The estimated output value of graphene produced from corn exceeds 300 million yuan ($42.9 million), news portal Science and Technology Daily reported on Tuesday.
The university cooperated on this research with the Shengquan Group, a Jinan-based chemicals firm, and set up the word's first manufacturing line dedicated to producing graphene from biological sources in 2014. It produced 20 tons of graphene from corn fibers in its first year and later expanded its annual output to 100 tons in 2016.
This breakthrough will help Heilongjiang put its agricultural waste to good use, said Yu Lihe, deputy director of Heilongjiang's Science and Technology Department.

I remember watching a documentary about graphite mining and the low yield of graphene from such sources. Making it out of biological sources is a breakthrough.
