Why lithium prices are rising again and what that means for battery costs

Lithium has become one of the most volatile raw materials of the energy transition. After a dramatic boom-and-bust cycle that has reshaped the battery industry, prices are rising sharply again in 2025–2026. For anyone investing in or specifying battery energy storage systems, it is becoming increasingly important to understand what drives these fluctuations and what protects against them.

From the electric truck to the grid

From an evaluation project for e-trucks of a partner company, eight large traction batteries with a nominal capacity of 560 kWh were recovered for a second life. The areas of application for these batteries are highly limited, making them unattractive for smaller applications, especially since they could only function when connected as clusters of 4 batteries. Therefore, it was clear that a large storage system should be created from this, which can stabilize the Swiss power grid.
