Laying a Foundation for Energy Abundance

Bedrock Materials develops and produces active materials for sodium-ion batteries, a low-cost and earth-abundant alternative to lithium-ion batteries.

Sodium-Ion Batteries are the Backbone of the New Energy Economy

Unlike modern lithium-ion batteries which rely on critical minerals like nickel, cobalt, lithium, and copper, sodium-ion batteries rely largely on manganese, iron, sodium, and aluminum. The extraordinary abundance of these materials eliminates price volatility and supply chain insecurity.

Megatons of Electrode Materials are Needed to Meet Global Demand

Sodium-ion batteries can be manufactured using the same equipment and infrastructure as lithium-ion batteries, but the engineered active materials they require are not yet produced at scale. That's where we come in.

Bedrock Materials designs, engineers, and manufactures sodium-ion cathode materials based on earth abundant metals. We specifically tailor our materials to meet the needs of underserved applications in mobility markets, such as low-voltage, starter-lighting-ignition, micromobility propulsion, and industrial traction.

As an North American supplier, we also help battery makers take advantage of tax credits such as those found in the Inflation Reduction Act.

Why Sodium-Ion Today?

Sodium-ion batteries deliver somewhat less energy density than lithium-ion, but recent advancements have finally made them competitive for entry-level markets.

Vehicle Efficiency

Today’s electric vehicles travel 35% further on the same energy as vehicles from 12 years ago.

Group 136 (4)

Fast Charging

Charging is three times faster and 10 times more ubiquitous than ten years ago, reducing range requirements

Battery Packaging

Modern battery packs use space 50% more efficiently, improving pack-level energy density regardless of chemistry choice

Technology Designed for the Mass Market

Sodium-ion batteries are a natural fit for segments of the market where cost, abundance, and safety are prioritized over premium performance.

Dependent on critical minerals

  • Lithium
  • Copper
  • Nickel
  • Cobalt
  • Phosphorous
  • Graphite

Premium energy density (500 Wh/L+)

Group 140 (4)

Few or no critical minerals

  • Iron
  • Manganese
  • Sodium
  • Aluminum
  • Carbon

Mass market energy density (300 Wh/L+)

Bottom-up Disruption

Today's best sodium-ion batteries can nearly match the energy density of LFP. As they increase in cycle life, their utility will expand to increasingly lifetime sensitive applications.
