Yeah, that's the thing, if you exclude voltage, capacity, and efficiency there's rechargeable batteries on grocery shelves that already meet the claims they made. Though they implied performance would surpass that of a Li-Ion cell, but they didn't back it up with any specs.
You hear these next new battery claims all the time. I've been hearing them for years and have yet to see anything that beats a Lithium based cell. I tend not to believe them, but still would love to see something better.
