Product Development Pathway
(5 R&D Concepts – Sulfide Glass Track)
Melt-drawn freestanding vitreous sulfide separator, formed so that neither major surface contacts tooling and the sheet carries none of the inter-particle boundaries that act as dendrite initiation sites in electrolytes pressed from powder.
Lithium-free moisture barrier film that seals the hydrolysis-sensitive glass during handling and converts in place into a conducting interphase once lithium is deposited onto it, with a liquid-wetted transfer route as a parallel handling option. Further concepts address stable lithium contact without external stack pressure, continuous ion transport through thick positive electrodes at high areal capacity, and defect control throughout continuous separator production.
Key Synergies
A single glass chemistry potentially spanning separator and positive electrode, joined to lithium by two independent interface routes – parallel de-risking of dendrite resistance, moisture handling and areal capacity for a manufacturable lithium-metal cell.
