Tesla has a battery breakthrough in the wings to power the Roadster 2020 model and Semi. It's not known the exact technological breakthrough but a huge number of signs point to this including unspecified plans for new battery cells.

Maxwell had been talking about a potential “strategic partnership” in the works for a few months regarding its dry electrode technology.

(The S and X models of Tesla have not updated to the new battery 2170 and this may be why.)

pdf on the technology

Besides making pseudocapacitors, a component that falls between a battery cell and a supercapacitor, it has developed a dry battery electrode with impressive energy storage potential. According to a slide (above) from the company’s recent presentation (PDF), the tech has been demonstrated the ability to hold over 300 Wh per kilogram and could possibly go as high as 500 Wh/kg. That’s a significant improvement over chemistries in today’s top lithium batteries which are in the 250 Wh/kg neighborhood. The cobalt-free formulation could ease the way for Tesla to develop a solid-state battery.

This type of technology partnership with Tesla would be good enough to reach Roadster/Semi design goals.

Little underwhelmed, they need supercapacitors for regenerative braking that isn't just braking, and better acceleration. Maxwell aren't fantastic manufacturer but presumably they think they've got something.

This makes little sense.
Tesla partner Jeff Dahn recently made a breakthrough in batteries with cobalt using additives in the electrolyte.

Yeah tesla busting out 200 million dollars to purchase this company at this point in economic cycle is a huge sign of a big change.

They also laid off employees but just spent big.
