Lithium
An icon so true
Lithium reigns supreme in the short-term energy storage octagon. Not found in its elemental form in nature due to its high reactivity, it can be mined from brines (accounting for nearly 70% of global Lithium resources), hard-rock deposits (w/ shorter lead times), and clays (still in infancy). Mining, however, is just the tip of the iceberg. A brief overlook of the Lithium supply chain can be found here.

Despite of supply constraints, Lithium high energy density & lightness is key i) to produce devices such as cell phones (6 billion+ in use today), tablets & notebooks, ii) to make mobility sustainable with electric vehicles (EVs), and iii) to support stationary energy storage applications (FTM & BTM).
According to the USGS 2026, the countries with the largest lithium reserves are Chile (9.2 Mt of lithium content), Australia (8.4 Mt), China (4.6 Mt), and the U.S. and Argentina (4.4 Mt each). In terms of mine production, Australia leads global output (92,000 t), followed by China (62,000 t), Chile (56,000 t), Argentina (23,000 t), and Brazil (12,000 t).
Alongside lithium, cobalt has long been a critical input in high-performance batteries, stabilizing the cathode while enhancing energy density, safety, and cycle life. The Democratic Republic of Congo is the world’s leading source of mined cobalt, accounting for an estimated 73% of global mine production, followed by Indonesia with about 14%. China remains the world’s leading producer of refined cobalt and the largest consumer, primarily for the lithium-ion battery industry.
Global lithium supply has expanded rapidly in recent years, resulting in a well-supplied market today, with no structural shortage for batteries and continued price pressure. However, investment in new mining and refining projects has slowed, while demand is expected to accelerate toward 2030, driven by electric vehicles and energy storage.
As of September 2026, battery-grade lithium carbonate prices are around USD 16,600 per ton, following a significant recovery from the low-price environment of 2025. The lithium market is tightening as demand from electric vehicles and, increasingly, energy storage systems continues to grow. Global lithium demand is expected to approach 2 Mt of LCE in 2027 and continue rising through the decade, increasing the need for substantial new supply capacity to maintain market balance.
