Substitutes

Substitutes and Alternatives for Lithium

The availability of viable substitutes is a key factor in assessing Lithium's criticality. Across its 4 primary applications, substitution options range from commercially viable alternatives with performance trade-offs to applications where Lithium currently has no effective substitute.

Substitution Analysis by Application

The following table details available substitutes for Lithium across its primary applications, including the trade-offs involved:

Performance Trade-offs

In most applications, substituting Lithium involves measurable performance penalties. Na-ion technology eliminates lithium entirely; lower energy density (~160 vs 250 Wh/kg) but cheaper and uses abundant sodium; CATL mass-producing for low-end EVs and energy storage since 2023. In high-performance applications such as lithium-ion batteries for evs, these trade-offs can be particularly significant.

Research and Development

Active research programs are underway to develop improved substitutes and to reduce the amount of Lithium required per unit of product (thrifting). However, timelines for commercializing new alternatives typically span years to decades. The limited substitutability of Lithium is a primary driver of its high criticality rating, prompting government-funded substitution research programs.
