Why Solid State for Batteries?Why Solid State for Batteries?Paradigm Changer

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

Game Changing Platform TechnologySolid State Energy/Monolithic Ceramic Batteries

Traditional Li-ion Battery

Planar’s – Solid State Battery

Solid State ArchitectureSolid State Architecture

• .5mAh/cm vs 20mAh/cm

• 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

Current solid state battery fabrication methods do not scale to large format batteries because of:
