Porous graphene and antimony interfaces on solid electrolyte layers, CNT-length optimization for silicon-carbon anodes, and compression-molded cathode materials with enlarged grain sizes
Key advances include solid-state interface engineering with porous graphene mechanical barriers, asymmetric lithium salts enabling roll-to-roll processing, and antimony-coated LLZO layers achieving 70 mA/cm² critical current density at 75°C. Silicon anode manufacturing advances through CO-enabled low-temperature CVD (365-380°C), multi-staged magnesiothermic reduction with 50% throughput improvements, and CNT fiber length optimization for network integrity. Cathode synthesis innovation progresses via compression-molding with vessel-free sintering for large grain sizes, direct metal to cathode active material manufacturing processes, and ferromanganese-based LMFP routes.
