Text on page 130
Large format li-ion battery manufacturing can be economically squeezed by low yield and low margins, the results of tight manufacturing tolerances and high-volume commodification, respectively. A general lack of rapid in-line inspection exists with some process steps having none at all. Slow feedback loops with inspectional data and iterative process improvements usually lead to multi-year production ramp periods. Large format market leaders like CATL have implemented better engineering, process control, controlled feedback loops, and benefited from standardized facility design to reduce scrap. Line Commission
