UBS hosted a two-day Virtual Solid State Battery Day featuring presentations from leading companies. The overarching theme indicates that next-generation battery technology is transitioning from pure hype toward quantifiable milestones centered on cost, manufacturability, scalability, and performance. A key consensus emerged: pressure-free or low-pressure solid-state architectures, including hybrid and semi-solid platforms, represent the ultimate industry goal.
Several technological pathways are showing tangible progress. ProLogium's ceramic platform targets an energy density of 470 Wh/kg without requiring the extreme 3,000-6,000 atm pressure typical of sulfide alternatives. Golden Feather is commercializing semi-solid batteries for niche markets, generating RMB 120 million in revenue for 2025, with projections reaching RMB 400-500 million in 2026. Manufacturing innovations are also advancing rapidly. AM Batteries' dry battery electrode process promises a 40% reduction in electrode capital expenditure, a claim bolstered by Tesla's adoption of similar technology in its 4680 cells.
Conversely, UBS maintains skepticism regarding the commercial viability of fully liquid-free solid-state batteries within the next decade. Sulfide-based paths pursued by leading Asian battery manufacturers continue to face unresolved extreme pressure bottlenecks. Consequently, UBS views hybrid and semi-solid platforms as possessing the most promising near-term commercialization prospects, offering superior manufacturability and cost efficiency. Innovations in vacuum roll-to-roll lithium films and advanced liquid systems containing silicon will likely dominate the decade.
