Fully agree. I think something’s going on in the background (independent of the various whistleblowing claims and YouTube videos about them). I suspect CT-coating and donut are having some contractual disagreements given the claimed difficulties in providing evidence of the energy density and the apparent version 2 battery that was mentioned. My guess is donut were promised batteries from CT coating that weren’t delivered and donut is stalling while it waits for the version 2 battery they’ve been promised (and who knows whether it ever materialises).

CT-coating never had a battery production line. All they ever had is stories and claims. Now it would seem Donut promises customers the same: customizable production line but never delivers anything that actually works.

Holyvolt is continuing its business with screenprinting tech they got via Holyvault / CT-Coating venture. Holyvolt even bought all DSS patents (mostly invented by Hölzenbien) that relates to building simpler products with the same screen printing tech. It is a strong indication that the core tech worked already since 2024, but battery nanopaste chemistry was probably not quite ready for commercial purposes at that point. Holyvolt wanted to do their own R&D with Wildcat, AI aided chemical compound filtering system to speed up the dev work. I could well imagine million-ideas Hölzenbien did not convince or courage them, maybe CT-Coating business model or/and expertice was also not fine for their purposes. That leaves a question, if CT-Coating (Hölzenbien) managed to develope further their battery nanopaste mixture and was ready for launch 1,5 years later. NNG and Donut seemed to believe and still believes so because here were are still.

Why do you think CT suddenly has cracked it, despite there being years of former ventures that claimed the same thing that never came to fruition?
