    Reading the article they got the info from, there still is a lot of work to be done. Different electrolytes to test as well as different SEI barrier thicknesses. Not to mention how they affect charging (still limited to .8C charge rate?) and discharge (still limited to 2 to 3C discharge rate?). Their research will produce their hoped for LiO2 battery but I'd say 4-5 years of research left on this one.

    However, I am impressed with this:
    Green Car Congress: PNNL team develops hybrid Mg-Li battery; excellent rate performance, safety and stability
    3000 cycles at 100 % DoD at 10C charge/discharge. 5% fade after 3000 cycles. 82% retention at 15C.
    And its a hybrid battery so it should be reported on Priuschat. Magnesium anode with magnesium electrolyte and Li ion intercalation cathode with lithium and magnesium electrolyte. Lets not get too excited because they are looking at using it for large static storage.

    It seems the batteries that Toyota is researching as the next big thing, solid state batteries, is further along than I thought and solid state batteries allows different players into the R&D field.

    Long-Lasting Solid-State Batteries Are Nearing Production | MIT Technology Review

    The key points to this design are:

    The people that actually make the equipment to make these batteries are actually making the equipment and developing the technology. This would make them much farther ahead than any of the other "holy grail" battery designs.

    The batteries they can make are much cheaper because they are made with the same semiconducting equipment that mass produce integrated circuits.

    Applied Materials is one of the largest semiconductor equipment suppliers in the world and to get them involved with battery R&D shows the industry high capacity battery manufacturing is not just a Tesla/Panasonic idea.

    The initial target is wearable technology, but they hope to move into EV market as well.

    They are probably at least a decade away for automotive. The air batteries (zinc air, aluminum air, lithium air) are probably much closer to comercialization Toyota is also working hard on lithium air. The waranty requirments on these solid state lithium batteries means years of tests for automotive after they make it to wearables.

    CEO of a certain solid state battery company has said 2 years and she will get her battery into cars. Consumer products this year.

    Li-O2 batteries are still 10 years away if ever. They have issues.

    She is dreaming. no car company is going to only test a battery for 2 years and replace the panasonic, samsung, or lg that is working. Waranty is too long, and aging is too hard.

    I think the first air batteries will be aluminum air or zinc air, not lithium air.
