China's Battery Cost Edge Triggers Lithium Price Decline

Lithium carbonate futures on the Guangzhou Futures Exchange fell to 144,000 yuan, a drop of nearly 5% after the market priced in a potential oversupply of lithium by 2027. The slide reflects the reopening of mines and expansion projects, including Australian operations, which could boost supply and erode the price premium that had supported producers.

The International Energy Agency warned that China's batteries are about 30% cheaper than those made in the United States and 35% cheaper than European equivalents in 2025. With China accounting for more than 80% of global battery production, the cost gap threatens the United States' clean‑energy transition by exposing it to supply concentration and higher costs for battery‑intensive sectors such as automotive and grid storage.
