China battery exports were 144GWh in the first 5 months of 2025 (of which only 3.4 GWh were destined for the USA). So we are probably looking at exports of 350GWh in 2025.
Year on year growth was 436%. It won't take many of those before they are exporting 1TWh / year.
A steady price of < USD 40/kWh by 2030 is looking pretty plausible right now.
