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

KEY FACTS

  • Customer programs underway in 3 continents

  • Strategic partners that are battery industry leaders, >$5B revenues

  • Supply and License business model

  • Fabless supply chain leveraging the solar industry

  • Capital efficient - updating factories at 1% the cost of a new Li factory

  • Protected by 46 patents in 23 countries

  • 100% recycling compatibility with traditional Lead Acid Batteries.
