Lithium “shortage” bubble implodes again
Lithium prices have fallen sharply from their recent peaks, prompting debate over whether this represents a speculative bubble deflating or a normal commodity cycle catching up with rapidly expanded mining and refining capacity. Commenters note that lithium itself is only a modest part of total battery cost, so EV and grid-storage prices are declining but not collapsing, while alternative chemistries like lithium iron phosphate and sodium-ion loom in the background. The thread also explores China’s dominant role in refining and price benchmarks, environmental and regulatory constraints on new mining (such as in Nevada), and the outsized impact of financial speculation on commodity volatility.
Lithium price dynamics & “bubble”
- Many see the recent spike and fall as classic commodity volatility: prices overshot on hype about EV demand and then corrected as new supply and expectations caught up.
- Others argue the headline is “clickbaity” because prices, while down sharply from the peak, are still far above 2020 lows and closer to pre‑pandemic levels.
- Debate over whether this was a true “bubble” or “rational speculation” given expectations of massive future demand and initially limited supply.
Role of China & pricing in CNY
- Lithium carbonate benchmark used in the article is traded in Shanghai and quoted in CNY.
- China is a leading refiner and battery producer, so refinery costs in CNY make that a natural reference price.
- In 2022 China reportedly paid much more than US/EU; suggested reasons include trade frictions (e.g., with Australia), logistics constraints, surging domestic demand (especially for solar), and speculative trading.
Impact on batteries, EVs & storage
- Lithium is a minority share of total battery cost (estimates around 10–20% of cell materials, less of full pack).
- Even during price spikes, overall battery pack $/kWh kept declining due to manufacturing improvements and cost distribution across many materials.
- Lower lithium prices help but are not expected to dramatically drop EV prices soon, as packs/enclosures, other materials, design choices, and profit margins dominate.
- Some foresee a future glut in battery manufacturing capacity that could briefly make storage and EVs very cheap.
Battery tech, DIY, and safety
- Users report large price drops in LiFePO4 (LFP) batteries and suggest this is a good time to expand home and utility‑scale storage.
- DIY pack building is described as “very doable” but potentially dangerous, especially with fire risks; LFP and LTO are seen as safer than conventional Li‑ion, with strong emphasis on good BMS and fire‑safe installation locations.
- Some prefer commercial packs for QA and recall mechanisms, though safety can never be guaranteed.
Alternatives, resources & environment
- Sodium‑ion batteries are discussed as a promising future alternative, but not yet at scale; cheaper lithium may slow their adoption.
- Several commenters stress lithium’s overall abundance (including in seawater) and argue true long‑term shortages are unlikely; others emphasize extraction cost, ore grades, water use, and local environmental damage.
Mining policy and US deposits
- A major Nevada deposit raises questions about timing: mine now vs treat as a strategic reserve.
- Disputes center on environmental impacts, water in arid regions, tribal rights, permitting delays, and foreign ownership, versus the need for domestic, cleaner‑energy supply chains.
