Overview

• Date: 3rd May, 2024
• Presenter: Ulf Krohn, VP Research & Development at Polarium

Key Points

Importance of Lithium-ion Batteries

• Increasingly vital with the shift to electric vehicles and renewable energy integration.
• Significant technological advancements have positioned lithium-ion batteries as essential for a battery-powered world.

Transitioning Battery Markets

• The move from lead to lithium in the stationary battery market.
• Emerging materials like solid-state batteries furthering lithium's dominance.
• Sodium-ion batteries as a cost-effective, safe, and sustainable complement to lithium-ion batteries.

Chemistry of Lithium-ion Batteries

• Not a single chemistry but a family of chemistries using intercalation.
• Two dominant chemistries:
  1. Nickel-based:
     • NMC (nickel manganese cobalt oxide)
     • NCA (nickel cobalt aluminum oxide)
  2. Iron-based:
     • LFP (lithium iron phosphate)
• These serve as positive electrodes, often referred to as cathodes.

Replacement of Lead by Lithium

• Lead-acid batteries have low gravimetric energy density (~30 Wh/kg).
• Lithium-ion batteries offer approximately ten times the energy density.
• Cost reduction in lithium-ion batteries facilitating industry-wide adoption over lead for stationary applications.
• Benefits include lower total cost of ownership, reduced space and weight, increased cycle life, and reduced self-discharge.

Potential of Solid-state Lithium-ion Batteries

• Expected incremental improvements in energy density.
• Future major advancements with the introduction of lithium metal negative electrodes.
  • Anticipated energy density increase of 30-50%.
• Solid-state batteries replace liquid electrolytes with solid-state materials, enhancing safety.
• Commercialization within the next 5-10 years.

Sodium-ion Batteries as a Complement

• Operate similarly to lithium-ion batteries but use sodium ions (Na+).
• Cost-effective due to sodium's abundance and sustainability.
• Lower energy density than lithium-ion but suitable for stationary storage.
• Significant resources invested in improving sodium-ion battery performance.
• Partnership between Polarium and Altris for developing sodium-ion based solutions.
