Overstated Lithium Forecasts, CATL, Semi-Solid Batteries, Battery Costs, BESS | Cormac O'Laoire

42 minutes

In this December 2025 episode of the Recharge Podcast, we (Matt Fernley, editor of Battery Materials Review, and Cormac O’Laoire, MD of Electrios Energy) break down the key developments shaping the battery supply chain as we head into 2026.

(41:48) Closing

We start with why we think parts of the market may be overstating future lithium demand—particularly assumptions around lithium intensity per kWh and average EV pack size. We discuss how consumer preferences for SUVs and crossovers intersect with affordability, and why that matters for long-term demand modelling across Europe and China.

We also look at near-term supply dynamics in China, including the situation around CATL’s lithium asset and what low-grade resources mean for cost and production decisions. On technology, we use NIO’s 150 kWh semi-solid pack as a real-world case study for the current economics of semi-solid and solid-state batteries, and where those technologies may find early adoption (including aviation and low-altitude electric flight).

Finally, we review the latest signals on battery costs—including pack prices around $108/kWh and recent indications of cell price increases tied to lithium carbonate and cobalt. We then shift to BESS (battery energy storage systems): strong shipment momentum, project delays, inventory build concerns, and why we see energy storage becoming increasingly strategic infrastructure—especially as utilities, grids, and data center demand accelerate.

We close with what we’re watching for 2026: lithium price sensitivity, the economics of longer-duration storage, and when alternatives like sodium-ion and flow batteries could become more competitive.
