Technology Assessment: Can an architecture retaining compatibility with conventional liquid electrolyte cell production overcome the 'escalating capacity loss' pattern inherent in lithium metal cycling? The chapter examines how SES's spatially differentiated electrolyte approach positions against the central cycle life barrier, how near-term drone/UAM commercialization complements longer-term EV development, and how public statements align with what the patent portfolio reveals about development priorities.
Product Development Pathway
(5 R&D Concepts)
Dual-polymer composite protective layer system for lithium metal dendrite suppression at the anode interface. Co-salt electrolyte architecture with sulfonyl-containing solvents for plating/stripping efficiency. Further concepts address mixed cathode architectures for thermal runaway mitigation, conductive adhesive coatings for large-format anode fabrication, and in-situ gel polymer electrolytes.
Potential Synergies to Deliver Well-Rounded Cells for Application
Anode stability, electrolyte optimization, and thermal safety addressed through independent but complementary concept pathways – enabling parallel de-risking of cycle life, safety, and manufacturability.
