Battery technologies critical minerals demand is the defining commodity story of the energy transition. The International Energy Agency projects that battery and energy storage deployment will account for the majority of new critical mineral demand through 2040 — drawing on lithium, cobalt, nickel, manganese, vanadium, and, indirectly, rare earth elements through the electric motors that pair with every battery system. This ranking scores ten commercially deployed or near-commercial battery chemistries by current deployment scale and critical mineral intensity.
One distinction matters before the rankings: rare earth elements do not, with one exception, sit inside the battery cell itself. The REE-battery link runs through the electric motor — specifically the neodymium-iron-boron (NdFeB) permanent magnet that powers the traction drive in most battery electric vehicles. The exception is nickel-metal hydride (NiMH) batteries, which use lanthanum and cerium directly as electrode material at 20–30 grammes per kWh. Both pathways are covered below.
How We Ranked the Top 10 Battery Technologies Critical Minerals
Entries are ranked by two criteria weighted equally: current global commercial deployment (GWh installed or manufacturing capacity committed) and critical mineral intensity per kWh of storage capacity. Technologies that combine wide deployment with high mineral dependency rank highest. Emerging technologies are included where they represent confirmed large-scale investment programmes rather than laboratory results.
1. NMC Lithium-Ion — Nickel Manganese Cobalt
NMC lithium-ion is the dominant EV battery chemistry in Europe and South Korea, commanding an estimated 40–45% of global EV battery production by capacity. A typical NMC811 cathode (80% nickel, 10% manganese, 10% cobalt) requires approximately 35–40 kg of nickel, 5 kg of manganese, and 5 kg of cobalt per 75 kWh pack. CATL, Samsung SDI, LG Energy Solution, and SK On are the primary manufacturers.
The shift from NMC111 to NMC811 since 2020 has reduced cobalt intensity by roughly 65% while increasing energy density to 250–300 Wh/kg. China imposed export controls on graphite — used as the anode material across all lithium-ion variants — in late 2023, adding supply chain risk to an already concentrated input base. Critical minerals: lithium, nickel, cobalt, manganese, graphite.
2. LFP — Lithium Iron Phosphate
LFP (lithium iron phosphate) surpassed NMC in global EV battery volume in 2023, driven by CATL’s Shenxing and BYD Blade platforms. LFP eliminates cobalt and nickel entirely, relying on lithium, iron, and phosphate — all lower-risk supply chains. Energy density runs 150–200 Wh/kg at cell level, below NMC, but thermal stability and cycle life (3,000–6,000 cycles versus 1,000–2,000 for NMC) make it the chemistry of choice for commercial EVs and stationary grid storage in China.
Tesla adopted LFP for its standard-range Model 3 and Y platforms. BYD, CATL, and SVOLT control the majority of global LFP production. Critical minerals: lithium, iron, phosphate (lower intensity than NMC or NCA).
3. NCA — Nickel Cobalt Aluminium
NCA (nickel cobalt aluminium) is the chemistry behind Tesla’s legacy 2170-format cells produced with Panasonic at Gigafactory Nevada. NCA delivers high energy density — up to 300 Wh/kg at cell level — but at higher nickel and cobalt content than NMC811. A typical NCA cell uses approximately 80% nickel and 15% cobalt by cathode weight.
Tesla has progressively shifted new vehicle programmes toward LFP or its 4680 structural cell platform, which uses an NMC variant. NCA’s share of global EV battery output is declining, though Panasonic’s Wakayama and Kansas facilities remain active. Critical minerals: lithium, nickel, cobalt, aluminium.
4. Nickel-Metal Hydride (NiMH) — The Rare Earth Battery
Nickel-metal hydride (NiMH) is the one battery chemistry with direct rare earth content in the cell. The negative electrode uses a rare earth-based AB₅ alloy — typically LaNi₅ or a mixed rare earth variant — consuming 20–30 grammes of rare earth metal per kWh of capacity. Lanthanum and cerium account for the majority of this demand; neodymium is present in smaller quantities depending on the alloy formulation.
NiMH dominated hybrid electric vehicles through the 2010s and remains standard in Toyota’s hybrid fleet, including the Prius and Camry Hybrid. Global NiMH demand for HEVs remains substantial: Toyota sold over 3.4 million electrified vehicles in 2023, the majority NiMH-powered. Shin-Etsu Chemical and TDK are among the major suppliers of the rare earth electrode alloys. For more on the rare earth elements used in this chemistry, see the neodymium profile and the top 10 uses of neodymium. Critical minerals: lanthanum, cerium, neodymium (REEs), nickel.
5. Solid-State Lithium
Solid-state lithium batteries replace the liquid electrolyte with a solid ceramic, sulphide, or polymer conductor, enabling higher energy density (projected 400–500 Wh/kg at pack level) and eliminating thermal runaway risk. Toyota has committed to commercial solid-state EV production by 2027–2028; Samsung SDI and QuantumScape have active gigafactory investment programmes.
Critical mineral demand from solid-state is not yet fully characterised at scale. Sulphide electrolytes require germanium or lithium phosphorus sulphide compounds; oxide electrolytes use rare earth dopants (typically lanthanum or yttrium) to stabilise the ceramic structure. The cathode chemistry — likely NMC or NCA — preserves existing nickel and cobalt demand. Critical minerals: lithium, nickel, cobalt, germanium (sulphide variants), rare earth dopants (oxide variants). Treat projected timelines as targets, not confirmed production dates.
6. Hydrogen Fuel Cells — Platinum Group Metals and Cerium
Hydrogen fuel cells generate electricity through an electrochemical reaction between hydrogen and oxygen, producing only water as a byproduct. Proton exchange membrane (PEM) fuel cells — used in Toyota Mirai, Hyundai Nexo, and commercial vehicle programmes from Daimler Truck — require platinum and iridium as catalyst metals at approximately 0.3–0.5 g/kW of rated output.
The rare earth connection: cerium oxide (ceria) is used as a catalyst support and electrolyte material in solid oxide fuel cells (SOFCs) and as a membrane stabiliser in PEM systems. Demand per vehicle is small — typically 5–15 grammes — but it links the hydrogen economy directly to REE supply chains. China’s export controls on critical minerals have raised supply risk for several fuel cell material inputs. Critical minerals: platinum, iridium (platinum group metals), cerium (rare earth).

7. Vanadium Flow Batteries
Vanadium redox flow batteries (VRFBs) store energy in liquid vanadium electrolyte solutions held in external tanks, enabling capacity to be scaled independently of power output. This makes them suited to multi-hour grid storage — 4–12 hour discharge durations — where lithium-ion is cost-disadvantaged. Cycle life exceeds 20,000 cycles with minimal degradation.
China controls approximately 60% of global vanadium production, concentrated in Panzhihua, Sichuan. Rongke Power, the largest VRFB manufacturer, commissioned a 100 MW / 400 MWh project in Dalian in 2022 — the world’s largest operational flow battery installation. Critical minerals: vanadium (high intensity — approximately 8–10 kg per kWh of storage capacity).
8. Sodium-Ion
Sodium-ion batteries substitute sodium for lithium in the intercalation chemistry, eliminating lithium, cobalt, and nickel from the cell entirely. CATL launched commercial sodium-ion production in 2023 for low-speed EVs and stationary storage. BYD, HiNa Battery, and SVOLT have active sodium-ion programmes.
Energy density currently runs 130–160 Wh/kg at cell level — below LFP — but the lower raw material cost and the absence of supply-constrained inputs make sodium-ion strategically significant as a lower-critical-mineral alternative for price-sensitive applications. Critical minerals: manganese (some variants), copper, aluminium — no lithium, cobalt, or nickel. Data source: USGS National Minerals Information Center.
9. Lithium-Sulphur
Lithium-sulphur (Li-S) batteries use sulphur as the cathode material, eliminating cobalt, nickel, and manganese from the cell. Theoretical energy density reaches 2,600 Wh/kg at the material level, though practical cell-level performance sits at 400–600 Wh/kg in current prototypes — still approximately double the best NMC cells. Lyten (USA) and Oxis Energy (now restructured) have led Western development efforts.
Commercial deployment remains limited by the polysulphide dissolution problem, which causes rapid capacity fade over cycling. Lithium demand remains high — roughly similar to NMC on a per-kWh basis — but the elimination of cobalt and nickel represents a meaningful reduction in supply chain concentration risk. Critical minerals: lithium (high), sulphur (abundant, low-risk).
10. Zinc-Air
Zinc-air batteries use zinc oxidation at the anode and ambient oxygen at the cathode, achieving energy densities of 400–500 Wh/kg at the material level. Manganese dioxide is commonly used as a catalyst. Form Hydro and EOS Energy are developing zinc-air systems for multi-day grid storage applications where low cost per kWh matters more than power density.
The critical mineral footprint is the lowest of any chemistry in this ranking — zinc and manganese are both abundant, widely mined outside China, and not subject to export control regimes. Rechargeability remains a technical challenge at scale, limiting current commercial use to primary (single-use) applications and early-stage grid pilots. Critical minerals: zinc, manganese (low intensity, low supply risk).

The Outlook for Battery Technologies Critical Minerals
The mineral intensity of global battery deployment is shifting rather than simply growing. The rise of LFP and sodium-ion is reducing cobalt and nickel demand per vehicle; the rise of solid-state lithium may reintroduce rare earth dopants at scale. The most durable REE demand signal sits not in the cell but in the motor: every battery electric vehicle that uses an NdFeB permanent magnet motor is a rare earth offtake event regardless of which battery chemistry it carries. That motor demand — anchored by neodymium and dysprosium — is the REE sector’s most direct exposure to the battery transition.
Supply chain concentration remains the common risk across all battery technologies critical minerals. China dominates processing of lithium, cobalt, graphite, and rare earths; controls the majority of vanadium output; and has demonstrated willingness to deploy export controls when strategic priorities demand it. See the rare earth applications in the energy transition for a broader analysis of how these dependencies are being addressed by Western supply chain programmes.

Which battery technologies use the most critical minerals?
NMC lithium-ion has the broadest critical mineral footprint, requiring lithium, nickel, cobalt, manganese, and graphite per cell. NCA shares a similar profile. Vanadium flow batteries use the highest concentration of a single critical mineral — approximately 8–10 kg of vanadium per kWh of storage capacity.
Do rare earth elements appear in EV batteries?
Not directly in most EV battery cells. The primary rare earth link in electric vehicles runs through the NdFeB permanent magnet motor that pairs with the battery pack — consuming neodymium, praseodymium, and dysprosium. The exception is nickel-metal hydride (NiMH) batteries, widely used in hybrid vehicles, which contain 20–30 grammes of rare earth metals (primarily lanthanum and cerium) per kWh in the electrode alloy.
What critical minerals are in lithium-ion batteries?
Lithium-ion batteries use lithium and graphite across all variants, plus chemistry-specific cathode metals: cobalt, nickel, and manganese in NMC; nickel, cobalt, and aluminium in NCA; iron and phosphate in LFP (no cobalt or nickel). Graphite used in anodes is subject to Chinese export controls introduced in late 2023.
Are solid-state batteries less reliant on critical minerals?
Solid-state batteries retain high lithium demand and, depending on cathode chemistry, continue to use nickel and cobalt. Sulphide-based electrolytes may require germanium; oxide-based electrolytes use rare earth dopants such as lanthanum or yttrium to stabilise the ceramic structure. Solid-state is not lower in mineral intensity than lithium-ion — it redistributes the critical mineral mix.
Which battery technology uses rare earth elements directly?
Nickel-metal hydride (NiMH) batteries are the only mainstream rechargeable battery chemistry with direct rare earth content in the cell. The negative electrode uses a lanthanum-nickel or mixed rare earth AB₅ alloy. NiMH remains the dominant chemistry in Toyota hybrid vehicles. Hydrogen fuel cells also use cerium oxide as a catalyst support, representing a smaller but consistent rare earth demand source.
