Research Methodology

Independent corroboration across rolling mill operations managers, cathode procurement leads at Korean cell manufacturers, and METI battery subsidy program administrators underwrites the qualitative findings. Primary fieldwork captured plant-level production data from Jiangsu-Fujian corridor facilities alongside regulatory interpretation from compliance officers. Secondary validation drew from customs/trade data on spodumene concentrate flows, SEC filings of listed lithium producers, GB standards evolution documentation, and IEC 62660 protocol amendments. Bottom-up foil production estimates triangulated against top-down battery cell demand projections.

Rate-of-change decomposition across the projection horizon separates volume growth from specification premium capture. Segmentation modeling incorporated product type, thickness grade, end-use industry, and regional regulatory cluster dimensions. CAGRs were derived from rolling mill capacity utilization curves weighted against solid-state platform integration timelines. Forecast inputs included spodumene contract renegotiation patterns and JIS certification pipeline visibility for coil-type formats.

Underlying measurement precision varies by segment; ultra-thin foil specifications carry tighter precision than thick foil commodity grades due to prototype-scale production visibility. Forecasts reflect assumptions on METI subsidy continuation and MEE enforcement intensity that could revise materially. Stakeholders should weight assumptions against their own operating context.
