Earlier, Elon Musk had suggested that Tesla may be able to mass-produce longer-life batteries with 50% more energy density in three to four years.
Musk may also reveal details about his company’s Roadrunner project, a proprietary battery cell manufacturing process, which debuted early this year.

No mention of maxwell there - however take a look at this

Tesla acquired Maxwell Technology about a year ago. Maxwell specializes in the production of ultracapacitors, though this is not what Tesla plans to leverage for their EVs. Maxwell offers a new way to build lithium-ion batteries. The new breakthrough is called dry battery electrode technology.
Maxwell originally developed the dry electrode fabrication process to improve production efficiency and lower manufacturing costs for its ultracapacitor products. The innovation later proved to enhance the performance of battery cells, while also having a cost advantage over existing manufacturing processes. Maxwell's dry electrode technology, applied to battery cell fabrication, has the potential to increase the range and reduce the cost of Tesla's cars, two critical success factors for any EV manufacturer.
^ that's the bit they've stolen. Hence the langague use around the Murata production line in the recent RNS
