What does Elon Musk say about lithium batteries?
Elon Musk has consistently emphasized the strategic importance of lithium batteries in the global energy transition, framing them as critical to energy security and technological advancement. He famously stated, “Lithium batteries are the new oil,” highlighting their role in replacing fossil fuels for electric vehicles (EVs) and energy storage. Musk underscores lithium-ion technology’s centrality to Tesla’s mission, particularly its ability to reduce cobalt dependency—a metal with ethical mining concerns—while optimizing nickel utilization despite supply chain challenges.

Why does Musk equate lithium batteries to “new oil”?
Musk’s analogy positions lithium batteries as the cornerstone of energy independence, mirroring oil’s historical dominance. He argues that scalable battery production determines geopolitical competitiveness, much like oil reserves shaped 20th-century economies. Practically speaking, lithium-ion batteries enable renewable energy storage and EV adoption, reducing reliance on volatile hydrocarbon markets. For example, Tesla’s Gigafactories aim to secure battery supply chains as strategically as nations once guarded oil fields. Pro Tip: Battery cost volatility (e.g., 2021-2022 lithium carbonate prices surging 9x) necessitates vertical integration—a lesson Musk applied via Tesla’s mining partnerships.
How has Tesla addressed cobalt and nickel challenges?
Tesla reduced cobalt in batteries to near-zero levels by 2018 using nickel-rich NCA chemistries, addressing ethical and cost concerns. However, Musk identified nickel as the “biggest concern” for scaling production in 2021, prompting a shift to lithium iron phosphate (LFP) batteries for standard-range vehicles. LFP’s iron abundance mitigates nickel supply risks but trades energy density for stability. Pro Tip: Multi-chemistry strategies (NCA for performance models, LFP for mass-market EVs) balance scalability and performance—Tesla’s Model 3 exemplifies this approach.
| Chemistry | Cobalt Content | Energy Density |
|---|---|---|
| NCA | ~9% | 260-290 Wh/kg |
| LFP | 0% | 150-200 Wh/kg |

FAQs
Explosive EV demand outpaced mining output, while geopolitical tensions disrupted supply. Musk warned this volatility makes vertical integration essential for automakers.
Does Tesla still use cobalt in its batteries?
Tesla’s LFP batteries use zero cobalt, while high-performance models use NCA with ≤9% cobalt—down from 60% in early lithium-ion designs.
