Energy revolution? Grabat introduces its graphene batteries

narrator 11y ago
These are 1000 Wh/kg while lithium batteries are 100–265 Wh/kg.

  Thanks for the comparison. I had no idea how impressive 1,000Wh/kg was!

If it does not heat when short-circuited (as stated), where does the energy go? Does it only change the chemical structure of the battery, or what?
- XorNot 11y ago
  Into the wire. A battery which stays cool when short-circuited would have a negligible internal resistance, which is a big deal in battery tech. I don't believe this article yet, but it's not a non-sense claim (though it's a bizarre way of stating it).

    Plausible claim, but remain cautiously skeptical?

How to know when to believe this?

  When you can buy it.
  - hoodoof 11y ago
    ......and it works as advertised.
- bluejekyll 11y ago
  Suspicions are high. The claims are amazing. Greater energy density, lower heat, better charging and discharging performance, will be cheaper, less pollution for the environment. I want to believe, because this could be a huge breakthrough for all IoT devices. But like the other comment said, until it can be bought, it just sounds too good to be true.

    "10x improvement!" "Graphene!" Maybe someone's shorting tech stocks, I have no idea. No chance at all the article is real. Even a 2x improvement could make the front page of the NYT.

      > Even a 2x improvement could make the front page of the NYT. A 20% improvement would make front pages in a lot of places. If this is real and manufacturable, they are certain to get a Nobel price and get really stinking rich. Something in the announcement smells wrong to me, though.

There are some articles in the Spanish press. For instance, the newspaper "El Mundo" claims that the Chinese company Chint have paid 18 millions for the 10% of the Spanish company (http://www.elmundo.es/motor/2016/02/11/56bc7d6aca4741e31e8b461f.html http://www.elmundo.es/motor/2016/02/11/56bc7d6aca4741e31e8b4...). If those batteries work as stated, it sounds really cheap. It says that in a second phase the Chinese are going to invest 350 millions. Anyway, it seems that they are really building a factory in Murcia. As always, take extraordinaries claims with a grain of salt but looks like there is really something here.

Searching the internet it's amazing how little there has been published about this. Could be a hoax indeed. I found a little video of the official product launch: http://video.news.com.au/v/433181/Spain-New-graphene-batteries-unveiled-in-Madrid http://video.news.com.au/v/433181/Spain-New-graphene-batteri... Still not sure about this thing beeing real or not :)

Is this "introduces" as in "issued press release", or as in "now shipping in volume"? They write "The production of the battery is planned in two phases. First a plant in Yecla, Murcia, will be built accounting for an investment of 30 million euro and whose first production line will be ready by the end of this month." If they're not shipping samples next month, it's bullshit.
- prewett 11y ago
  Maybe the English translation is not accurate, but there's no way you can build a factory in a month, let alone have it shipping product. The article also has weird bold highlighting to make sure you quickly catch the amazingness. Makes me wonder if this is a pump and dump attempt.

its a scam, just like last months $4 smartphones.
