FHC- to your point 1- from our website-
Products and battery material components enabled by AnteoCoat™ nano-film binders are designed to offer the industry a path to increase storage capacity and manufacturers with an easy-to-implement, scalable and low-cost solution for volume production. For this reason, our water-based chemistry is perfectly suited to slot into existing and future battery manufacturing processes, avoiding the use of expensive and problematic organic solvents.

Now I am far from being a chemist however I do have a fairly solid grasp of water chemistry from my line of work... my layman understanding is our tech is water based although I have no understanding of what it is or isn’t added, something such as the addition of NACL (sodium chloride) would make it conductive.
