SILICON MATERIALS TRANSFORMING AN INDUSTRY
HIGH PERFORMANCE BATTERIES AT CONVENTIONAL BATTERY COSTS
Global Battery Market = $200 Billion by 2029
SILICON PROVIDES THE BEST OF BOTH WORLDS
BENEFITS OF LEAD…
Low cost
Safe
Sustainable (99%+ recycled)
Wide temperature range
Power density
…AND OF LITHIUM
Long cycle life
Fast charge/discharge rate
Deep depth of discharge (DoD)
Energy density
Power density
LEAD COMPONENTS UPGRADED TO SILICON WAFERS
TRADITIONAL LEAD BATTERY
Lead Current collectors:
Add weight but not performance
Electrolyte stratification limits lifetime
Hot spots from paste non-uniformity
Lead grid & strapping
Heavy!
Slow charging, short life, limited DoD
SILICON JOULE® TECHNOLOGY
Silicon current collectors:
Add performance and reduce weight
Uniform current distribution
Low impedance
Efficient thermal management
Lighter, no lead grids or strapping
Fast charging, long life, high DoD
