…Science and Technology for a Better World
Applications for High Value R2R• Next Generation Batteries
– Increased Energy Density, Cycle Life, and Safety with All Solid State Lithium Batteries• Low-Cost Window Films Compatible with Retrofit
– Dynamic Electrochromic Window Coatings– Low-e Window Films with Added Function
• Separation Membranes – Water Purification– Flow Batteries– Membrane Reactors, e.g. Biofuels Synthesis
• Multifunctional Technologies– Smart, Wearables: Electronic Textiles with Sensors, Power, and Communications
Integrated in Fabric for Health Monitoring, Security, etc.– Power Integrated into Structure: BIPV, Defense & Space (Power on wing of MAV), etc.
• Next Generation Solar/Energy Harvesting– Rectenna Based Energy Harvesting of Waste Heat

Summary• Many Industries Benefit from Roll-to-Roll Processing
– Smaller Footprint Equipment for Large Area Devices– Flexible Substrates Provide Enhanced Versatility for Product Integration– Economies of Scale
• Challenges are Similar Across Technology Space– Intelligent Process Controls Provide the Required High Throughput and High
Yield to Realize Economies of Scale– Nanodimensional Control of Materials is Required for Performance
Optimization– Mechanically Stable, Durable Low-Cost, Thin Substrates– Minimizing Temperature Required to Optimize Performance– Patterning of Materials into Devices, Particularly for Reactive and
Transparent Materials
