Why Solid State Batteries ?Why Solid State Batteries ?
Ceramic Battery Difference:Replace the plastics, binders, powders and liquids with durable, nanostructured films
Operating Benefits:•Long operating lives at optimal performance
•Elimination of shorts and battery failures
•50%+ reduction in cell weight & volume
•Fast recharge cycles
•Higher operating temperature ranges reduces thermal management challenges
•No liquids eliminates “thermal runaway”
Enabling new products & applications
•Battery/Capacitor hybrids

• Lipon is poor conductor •1-2 Orders of Magnitude Too Low
• Limited Cathode opportunities
Solid State MicroSolid State Micro--Batteries DonBatteries Don’’t Scalet Scale
Thin Films Have Limited Storage Capacity & Rates
Traditional Deposition Approaches are Expensive
• $100’s+ Sq M for Thin Film•Needs to be $1’s
• Slow Deposition Rates•Thin Film tough, Thick Film non-starter
• Complex Mfg. Processes & Device Designs/Packaging
