Neuartige additive Fertigungstechniken

We aim to achieve order of magnitude improvements in battery performance by using novel visible light polymerisation in particle rich slurries. By selectively hardening photopolymerisable compounds across very large areas at resolutions of 20 microns we can rapidly create significantly greater electrode contact.

We can also do this at low cost. LCD screens enable large areas to be encoded with light cost-effectively creating polymerisation at
very high resolution. Our novel viscous material dispensing system for particle-rich slurries allows large areas to be dispensed rapidly.

Photocentric konzentriert sich darauf, die Vorteile niedriger Kosten und des Produktionsmaßstabs zu nutzen. Industrialisierung des 3D-Drucks von Batterieelektroden, um die zusätzliche Leistung zu nutzen, die durch die Freiheit der Geometrie in drei Dimensionen entsteht.

Our Horizon funded AM4BAT project

The overall objective of AM4BAT is to develop an anode-free solid-state battery (SSB), fabricated by Vat Photopolymerization 3D printing by LCD reaching energy density of 400 Wh/kg and 1000 Wh/L for Electric vehicles (EV) applications.
