    Can anyone confirm that a "graphene-enhanced" battery will be used in the roadster? Stated here: http://www.wantchinatimes.com/news-subclass-cnt.aspx?id=20150104000004&cid=1202

    "A big breakthrough was achieved on Dec. 4 when the so-called super battery for electric vehicles which charges in eight minutes due to the graphene polymer technology was released by Spanish company Graphenano and the University of Cordoba in Spain.
    US electric car company Tesla Motors announced the launch of the Roadster 3.0 on Dec. 26, 2014. The 3.0 version of the car uses graphene in the production of the battery, which increases its energy storage capacity significantly. The battery range improves by 50% which enables the 3.0 version to travel 644 km on one charge, a non-stop drive from San Francisco to Los Angeles, according to Tesla."

    2 + orange = 4, apparently.

    My assumption was no... I am thinking that the Roadster 3.0 battery would be fairly conventional construction, just with the incremental improvements afforded by using current cells instead of ~2008 technology. Further, I think Roadster 3.0 may come with cells that are slightly less advanced than the Model S cells, but easier to integrate into the existing Roadster systems.

    I think I've come to the conclusion that it may be the just the same Model S cell... or slightly modified to fit in the Roadster pack dimensions.

    Model S: 85000 Wh/(3.1 Ah*3.6 V) = 7616.49 ~ 7617 cells
    Roadster 2.5: 53000 Wh/(2.2 Ah*3.7 V) = 6511.06 ~ 6511 cells

    *Roadster 3.0 (w/ Model S cell): 70000 Wh/(3.1 Ah*3.6 V) = 6272.40 ~ 6272 cells (less cells for the same space… )

    Searching on "graphene" and "tesla" in Chinese ( 石墨烯 特斯拉 ) returns very many results. It seems there is a media frenzy over graphene research, and Tesla's comments about range breakthroughs have many jumping to the conclusion that this must mean graphene cells are about to enter the market.

    One of the stories I saw:

    Wow, that article translation is all over the place. But may have some interesting nuggets. I'm gonna send this to my bro in China and see if he can dig up anything more on the two German companies supposedly producing in 2015. I love how they refer to Elon as the Godfather lol :D.

    Just moved the thread to the Battery section.

    New battery technology announcements are made on a daily basis. The majority will prove to have some killer limitation. The problem is, you have to optimize many variables at once, including energy density by volume, energy density by weight, power delivery, cycle life, temperature range, etc... all at the same time. If the cell doesn't perform on just one of these axes it will not be suitable for EV use.

    Eventually one of these announcements will pan out. But the odds seem to be like winning the lottery.

    For years we have been reading about new breakthroughs in battery tech. 500 mile range would be great. I am certain Tesla would be more than happy to have a working prototype for their research and sub-sequent implementation. Elon was quoted as saying “Just send one cell that works with all appropriate caveats”.

    The writer is just using the new journalistic rule: "Writing a boring story? Mention Tesla!"

    Hi guys!

    I've been reading you for a while, but never posted.

    I'm waiting the day when EV reach enough range (let's say real 300 miles) at an affordable cost, compared with ICE competitors. Hope M3 will be the one.

    I live in Spain where Tesla hasn't opened anything (just two superchargers), and I have a relative who is a happy (and adventorous as there isn't a tesla service point in Spain) owner of a Model S bought in the Netherlands.

    I'm writing just to say that there has been an announcement this month in Spain on the launch of the manufacturing of graphene based lithium batteries by the company grabat energy (subsidiary of graphenano).

    By now it's just an announcement... they state that the fist production lines will be working in march and they will be increasing capacity through the following years.

    They signed an agreement with a Chinese industrial partner (Chint) in order to develop their industrial plan.

    The caractheristics of those batteries are amazing (if it's right). .. increasing power density x5, reaching charging rates of 100 C (if the network stands it), or reducing volume requirements by 40%...

    Grabat introduces its graphene batteries - www.energynews.es | www.energynews.es

    In few months we'll see if this announcement is real or just smoke, but they state that have signed also agreements with German car manufacturers that are going to use their technology.

    I hope this will increase competition among manufacturers with new and better models (at a lower cost).

    In this interview he talks about charging a Tesla with a battery 5 times the KWH would require infrastructure to charge that car really thick charging cables and if everybody would charge at that rate the building power input would have to be huge

    I have this giant post on reddit about every spanish article I found about them.
