Nikola Corporation is excited to announce details of its new battery that has a record energy density of 1,100 watt-hours per kg on the material level and 500 watt-hours per kg on the production cell level. The Nikola prototype cell is the first battery that removes binder material and current collectors, enabling more energy storage within the cell. It is also expected to pass nail penetration standards, thus reducing potential vehicle fires.

This battery technology could increase the range of current EV passenger cars from 300 miles up to 600 miles with little or no increase to battery size and weight. The technology is also designed to operate in existing vehicle conditions. Moreover, cycling the cells over 2,000 times has shown acceptable end-of-life performance.

Nikola's new cell technology is environmentally friendly and easy to recycle. While conventional lithium-ion cells contain elements that are toxic and expensive, the new technology will have a positive impact on the earth's resources, landfills and recycling plants.

    According to that graph, then, this is nothing special.

    Unless you include that the *material* could be more dense, the actual *battery cells* (with all the packaging and gumpfh to make them work) are the same density as a top-end Li-Ion cylindrical cell.

    There are lies, damn lies, and press releases...

    Well, when I look at the graph I notice it more than doubles the gravimetric energy density. So that's no small improvement, if that's combined with other possible improvements like material costs, recycling options, ... I would even call it a jump forward.
    However, the phrasing of those additional benefits triggers my "marketing / lawyer speak" alarm. The lack of volumetric density details adds to those alarm bells. So yeah, may be not a jump.
