| Material / Subfamily | Primary Engineering Functions | Environment / Interfaces | Processing / Qualification Focus | Cross-Project Links |
|---|---|---|---|---|
| Solid-State Electrolytes | Solid ion transport and separator function for safer, high-energy electrochemical cells. | Electrode contact, grain boundaries, stack pressure, temperature, moisture sensitivity and dendrite paths control performance. | Density, phase purity, conductivity, interface resistance, fracture and cycling under realistic pressure/temperature require qualification. | Batteries · Ceramics · Prototype Qualification |
| Silicon-Dominant Anodes | High-capacity negative electrodes using silicon, SiOx and composite architectures. | Large volume change, SEI evolution, binder/conductive-network integrity and electrolyte compatibility dominate fade. | Particle morphology, prelithiation where used, electrode loading, swelling, fast-charge cycling and cell-level retention must be tracked. | Batteries · Nanotechnology · Manufacturing |
| Earth-Abundant Cathodes | Positive-electrode chemistries emphasizing resource resilience, cost, safety and scalable performance. | Phase transitions, dissolution, gas evolution, moisture sensitivity and electrolyte window remain chemistry-specific. | Stoichiometry, precursor control, coating/doping, calendering, thermal safety and long-cycle validation are primary gates. | Grid Storage · Sustainable Materials · Batteries |
| Perovskite Tandems | High-efficiency photovoltaic absorber stacks combining complementary bandgaps. | Moisture, oxygen, UV, heat, ion migration, interface recombination and encapsulation govern field stability. | Deposition uniformity, composition control, contact layers, encapsulation, accelerated aging and module-scale yield must be demonstrated. | Solar · Perovskites · Space Energy |
| Thermoelectrics | Direct conversion between heat flow and electrical power for recovery and thermal management. | Temperature gradient, contact resistance, thermal cycling, oxidation and coefficient mismatch set usable efficiency. | Composition, texture, joint metallurgy, ZT-related property sets, module cycling and contact durability need coupled validation. | Thermal Recovery · Space · Industrial |
| Electrocatalysts | Surface-mediated electrochemical conversion for hydrogen, oxygen, fuel-cell and electrolyzer pathways. | Potential, pH, impurities, gas transport, support corrosion, catalyst dissolution and poisoning determine lifetime. | Surface area/state, loading, support adhesion, half-cell versus device correlation and accelerated durability must be explicit. | Hydrogen · Reactors · Sustainable Infrastructure |
| Redox-Active Organics | Molecular charge storage for flow batteries and other stationary electrochemical systems. | Solubility, crossover, solvent/electrolyte compatibility, decomposition and membrane interactions dominate retention. | Purity, redox potential, solubility window, membrane compatibility, cycling and recovery/rebalancing strategies require validation. | Grid Storage · Sustainable Materials |
| Supercapacitor Materials | Fast charge storage through double-layer and pseudocapacitive mechanisms. | Electrolyte window, pore accessibility, ESR, self-discharge, thermal behavior and current collector interfaces limit power. | Surface area alone is insufficient; electrode density, pore distribution, conductivity, cycle life and device-level energy/power must be measured. | Grid Storage · Mobile Power · Nanotechnology |
