Sodium-Ion: Can it Challenge the Lithium-Ion Reign?

Deconstructing the Price Dynamics: Learning Curves and Price Floors

Understanding the cost trajectory of new battery technologies is crucial for assessing their potential market impact. Traditionally, analysts have relied on learning curves, which demonstrate how the cost of a technology decreases as cumulative production increases. The typical Wright’s learning curve follows the form
$$Y=A{x}^{-b}$$ (1)
where the price of a technology Y at a given cumulative experience x is described by the price of the first unit A and a rate of price reduction b. Here the learning rate (or experience rate) is defined as the percentage price reduction after every doubling of cumulative experience, given by
$${\rm{LR}}=1-{2}^{-b}$$ (2)

While learning curves effectively capture historical price trends, they can overestimate future cost reductions when technologies approach their physical limits. This is where the concept of “price floors” comes into play. Price floors represent the minimum cost at which a technology can be produced due to limitations imposed by material availability, manufacturing processes, or other factors.

This paper incorporates dynamically varying minerals price floors to capture the price evolution of individual component costs of a battery. This enables us to capture individual learning rates, market growth rates and price floors between material components, which are unlikely to always be the same.

Engineering the Future: Modeling Material Intensities and Cell Performance

To accurately model the potential of sodium-ion batteries, it’s essential to consider not just cost but also cell performance, which is directly influenced by material choices and design. This involves understanding how material improvements translate into real-world performance gains.

We adapt Moore’s Law principles to track material advancements in battery cell designs, using a modified equation to capture improvements as a function of time. This approach allows us to simulate how material innovations impact cell performance by analyzing the relationship between material intensity and cell-level specific energy.

Utilizing detailed component-level data, we employ a bottom-up cell design analysis to simulate the impact of material innovations on cell performance. This approach allows for a granular understanding of how changes in individual components affect the overall battery characteristics.

Finally, we identify theoretical and practical constraints on material usage and explore their implications for future battery technology. Understanding these engineering limits is crucial for setting realistic expectations and identifying potential breakthroughs.

Sodium-Ion vs Lithium-Ion: A Techno-Economic Showdown

A comprehensive assessment of sodium-ion technology requires a head-to-head comparison with the incumbent lithium-ion technology. We forecast the cost trajectory of sodium-ion batteries and compare it to lithium-ion, considering capacity growth and market penetration.

The analysis also delves into the resource availability and sustainability implications of both technologies. Sodium is significantly more abundant than lithium, raising questions about the long-term resource security and environmental footprint of each technology.

Furthermore, we identify key technological roadblocks and opportunities for sodium-ion technology to achieve competitive advantage. Overcoming challenges such as cycle life, energy density, and cost parity with lithium-ion will be crucial for sodium-ion batteries to gain widespread adoption.
