New Battery Tech From Japan Could Supercharge EVs 81

joe5 writes "Many experts suggest that battery technology is really the key to the future of transportation. Its certainly the key to unlocking Tesla for even further growth. Today, a Japanese startup called Power Japan Plus unveiled a new battery chemistry that could significantly improve transportation batteries. In testing, the recycle-able cell has completed more than 3,000 charge/discharge cycles with virtually no performance degradation, meaning that it could conceivably last the lifetime of a car. They company won't yet provide too many details due to pending patents, and won't even say who its first customer is — but the chemistry requires 'specific and proprietary changes to the nanostructure of the carbon crystals.'"

    PR like this claiming the next breakthrough in batteries has been coming out for years, but what actually makes it to production are basically minor tweaks to existing chemistry.

    Inevitably what happens is something keeps the technology from being mass produced, or is too expensive, or simply does not function as advertised.

    I hope I'm wrong, but I'm not holding my breath.

  • At present yours is the 4th comment and the 4th extremely skeptical comment.

    Quote from the article:

    Power Japan says a Ryden cell barely heats up during charge and discharge--it "experiences minimal thermal change" ...

    That means there is little electrical resistance, which seems impossible if both electrodes are made of carbon. Metal has low electrical resistance. The electrical resistance of carbon is much higher.

    A 2nd quote:

    ... an electric car's battery would hold its full energy over 10 years or more, ...

    That's another statement about electrical resistance. It says that there is effectively an open circuit between the battery terminals, a very high resistance. The battery would not drain itself. Seems impossible to me.

    The writer has a lack of understanding of technology:

    And equally important for practicality, the new dual-carbon anode and cathode can both be produced by existing cell manufacturing processes--and require essentially just a single material as input: carbon.

    That reduces the number of materials that must be procured for the supply chain, simplifying the entire production process.

    The BIG issue is that the battery would not use an expensive, scarce metal: Lithium. The fact that the author doesn't mention that indicates he understands extremely little.

    This is even more weird:

    Separate from the announcement of the Ryden battery, Power Japan Plus is also working on a new form of carbon that is entirely organic.

    The material, known as Carbon Complex, which is made using naturally-grown organic cotton that is then processed using special techniques to control the size of the carbon crystals formed during production.

    Early test cells are not produced with the organic carbon, but the company's goal is to create a battery cell that is not only competitive with today's lithium-ion cells but uses entirely organic input materials that can be fully recycled at the end of their life.

    That is so confused I decided not to comment on the confusion.

    Maybe the entire reason for the article is to find amazingly ignorant investors:

    Meanwhile, Power Japan Plus--which has been internally funded until now--is seeking its first investments of private funds.

    "Might" and "Could" seem to be very common words in battery development headlines.

Variables don't; constants aren't.
