Why Tesla's Pr Jeff Dahn was so excited about NVX's DPMG breakthrough!, page-2

A different perspective if we're assosciating with Tesla and from a competitive POV - Tesla's acquisition of Battery-tech / Super-capacitor company Maxwell's similar tech called Dry Electrode Technology which has already been successfully commercialised in making its supercapacitors. Google "maxwell dry electrode technology".

Maxwell’s electrode process works by fibrilizing bits of PTFE (Teflon) mixed with particles of active electrode material, resulting in a self-supporting film of anode or cathode material. The film is then laminated to a current collector foil to make an anode or cathode, which is wound up with separator film to form a battery cell.

As Carlson explains, the really cool thing about Maxwell’s process is that it makes electrodes without using solvent. His article describes the technical advantages of this in delicious detail, and battery boffins will want to read it in its entirety. Here we’ll just note that the solvents used in conventional Li-ion battery manufacturing are toxic and difficult to work with, and require the use of large and expensive electrode coating machines.

Maxwell’s dry electrode process is far simpler, and the company has already used it commercially to make its supercapacitors.
