Why aren't graphene batteries ready for mass production?

More and more enterprises join the graphene battery research and development manufacturing. Graphene batteries in a strict sense, however, has not yet entered the market, to become the new energy vehicles "heart", the dream in a short period of time is still difficult to achieve.

Is new energy to speed up the layout of Shanshan, a public announcement on the night of August 15, according to its subsidiary in Ningbo Shanshan new material technology co., LTD. Proposed investment cooperation agreement signed with the Baotou city government, will spend about $3.8 billion to invest in the construction in Baotou annual output of 100000 tons lithium ion batteries integration of the cathode base project, 50000 tons of graphite and carbide process.

Shanshan Xu Zheng shares vice President Peng said when accepting a reporter to interview, the enterprise of product more and more, graphene such as graphene in lithium ion battery cathode material as additive, can improve the electrical conductivity.However, graphene was just one of the lithium ion battery cathode materials, the market has yet to appear in the true sense of graphene batteries.Some enterprises which have can production graphene battery, it just biased.For now, the real graphene cells are too extravagant, cannot achieve production and marketing.

Another big lithium battery manufacturers of insiders reporter interview today, the current graphene battery into the market is not only the restriction of the price factor, in the production process, practicability, etc. have a long way to go.The enterprise very early research on graphene, also in graphene materials added to the lithium battery cathode material in the conductive performance, graphene is a new kind of raw materials, but about graphene power battery how to apply the temporary is still not clear.The enterprises is not optimistic about the development prospects of graphene battery, a longer period of time in the future, power battery development still in route planningThe ternary lithium battery and the lithium iron phosphate.

Gac GuHui south passenger cars, deputy general manager, gac for electric passenger car market competitiveness of careful evaluation, think that as long as the battery energy density to more than 150 Wh/kg, the price is lower than 0.6 yuan/Wh, can reasonable travel distance is 400 km.If the battery quick charging capability at the same time, such as 80%, 30 minutes is enough to cooperate with efficient filling combination screw pile, electric passenger cars alternative fuel cars at the same level will be come true.

At present, both at home and abroad in accelerating the development of new energy vehicles, push the car to the direction of electric, intelligent and interconnected."Heart" as the new energy vehicles, power battery field is blustery, large-scale influx of capital, promote the production capacity of the battery and technology rapid development, I hope as soon as possible by reducing the cost of power battery, improve the energy density and shorten the charging time, in order to promote new energy vehicles popularized.Currently, is the main lithium batteries on power battery, many enterprises will generally lithium iron phosphate and ternary lithium battery in the heart of electric vehicles, and constantly looking for new breakthrough in the technology.At the same time, there are some enterprises in the new technology research and development and reserves, technical route is more and more diversified, hydrogen fuel cells, such as graphene battery technology gradually rise.As currently found in the most thin, the intensity is the largest and strongest conductive heat conduction performance of a new type of nanometer materials, graphene is called "black gold", is "the king of new materials, scientists even predict graphene will" change "in the 21st century, is likely to set off a worldwide disruptive new technology and new industrial revolution.

Fujian province issued the graphene industry development planning of Fujian province (2017-2025) ", this is the first BuShengJi graphene special planning.Planning is put forward, by 2020, the province to build more perfect graphene materials research and development, preparation and application of industry development system;By 2025, the province graphene and its related products output value reached 50 billion yuan, drive the formation of more than 100 billion yuan output value of industry chain system.

As the world's largest new energy automobile market, China's new energy automobile sales volume rapid advances in recent years, although since this year because of new energy policy adjustment reason growth slowed, but still far outperform market the market. According to ministry of industry sales recently, July 1 - this year, new energy automobile production finished 272000 and 251000, respectively, year-on-year growth of 26.2% and 21.5% respectively. In view of the prospects of the development of new energy industry, local governments and businesses have a new opportunity.
