Organic Cotton Battery To Be Used For Racing

June 19th, 2014 by  

We’ve seen a lot of discussion in the comments of some posts about this organic cotton battery from Ryden. Now the organic cotton battery is coming to some racing cars!… well, sort of. Do go karts count?

The Organic Cotton Battery Is Going Racing (via Gas 2.0)

Perennial 24 Hours of Le Mans entrant Team TAISAN is aligning itself with Power Japan Plus, makers of the Ryden organic dual-carbon cotton battery to build a fast-charging electric go kart. The goal is to fast track this technology to production vehicles…

Check out our new 93-page EV report, based on over 2,000 surveys collected from EV drivers in 49 of 50 US states, 26 European countries, and 9 Canadian provinces.

    If this was a “game changing” battery, they would send some 8000 18650 format cells into Fremont California and let Tesla to pack it as a demonstration battery for AWD Model S. This way we could se how it performs in real life.

    But of course they won’t to do this, because they actually do not have yet a prototype that is ready for production and real world testing.

    Therefore, before this gets to markets, we have seen dozens of new lab prototypes and the cost of lithium-ion batteries has gone down so significantly that this does not have anymore markets.

      If this does live up to PJP’s claims then I think it would replace Li-ion in a lot of applications, including EV’s. Especially since it uses very common materials and should fit right in to existing production methods.

      Since one of their main researchers also worked on the Model S and Prius battery, I think they have a decent reputation and won’t be making bogus claims. Of course we’ll have to wait for august to have some concrete results I guess, but I’m very hopeful.

  • vensonata

    I’d love to believe this. Why do i not?

    • Bob_Wallace

      Perhaps it’s because by now we’ve observed many great sounding ideas fizzle?

  • Carbon supercaps with solar cells might even keep a charge over a summer holiday for domestic cars, if they’re not plugged in to help buffer the grid.

  • Kris Trader

    everyone visit the http://WWW.POWERJAPANPLUS.COM website ryden battery can recharge twice as many times as todays best batteries the Japanese scientist have saved the world from the internal combustion engine , there are many applications for the dual carbon battery technology from medical communications transport etc

    • Bob_Wallace

      You’re getting ahead of the data.

      Ryden batteries are promising. But there have been many promising technologies that never actually made it all the way to the finish line.

  • Omega Centauri

    Maybe? A battery which only lives a single charge/discharge cycle could be just great for a racecar, but useless for real world applications, where cost per mile is important.

    • Matt

      Recharges 20x faster, sounds like a rechargeable battery to me.

      • Omega Centauri

        Sure. But how many cycles can it handle? The fcat racers like it doesn’t prove it has realworld benefits.
        The recharge speed isn’t really the issue, its the amount of power required -which won’t change much with this battery. Charging from 120volts, means you are limited to roughly 1500watts -or twenty hours for a 30KWhour battery -based upon the power mains/ not the battery type.

        • Wayne Williamson

          Yeah, that drastically reduce charge time from a standard outlet is just a lie. I would probably bump it to 2kwh per hour using 110v and 20 amp fuses.(110,115,120v all the same thing;-)

        • Bob_Wallace

          One site claims 3,000 cycles. Which would make it a winner.

          3,000 cycles x 200 mile range = 600,000 mile battery.

          No data on calendar life nor independent verification of the 3k cycle claim.

          Charge time under normal use won’t be a factor. The “average” or less driver can charge up with a 120 vac outlet.

          The really high mileage drivers will need a bigger pipe.

          Working off the Nissan Leaf data – “Models with an on-board 6.6 kW charger can be fully recharged from empty in 4 hours from a 220/240-volt 40 amp supply (7.7 kW allowable draw) that can provide the on-board charger its full 6.6 kW of usable power.” (Wiki)

          If one can charge 73 miles (EPA range) in 4 hours with a 240 vac 40 amp then over 150 miles in 8 hours is possible.
          People who drive ~200 miles per day are going to be a very small portion of the fleet.

      • Benjamin Nead

        I think what Omega Centauri is implying, Matt, is that a battery which can stand up to a short and concentrated race, but then completely discarded before the next race, isn’t the same sort thing as a battery that might lead a much more leisurely daily existence, but then expected to do so for many years.

        Nothing I’ve read about the “organic cotton” battery (referred to more technically as the “dual carbon” battery on other web sites) indicates that it’s a racing-only item with a miserably short shelf life. But, yes, let’s see it exposed to an intense LeMans-style race and then lets also see some of these batteries live in a few “mom & pop” EVs placed in diverse (both super hot and super cold) climates over an extended time period. All of it is important R&D.

  • Kompani

    One to watch.

    • Jouni Valkonen

      There are dozens more promising battery technologies to watch.

      • Kompani

        There indeed are but there’s usually something that comes out of left field that can make a step change to a technology rather than evolve one. That’s why I try and read and understand as much about the ‘fringe’ (not stupid) stuff as well as the mainstream advances. Helps keep the mind open to new ideas rather than blinkered on the existing ones.
