Battery cathode with high nickel content has the advantage of high energy density and great storage capacity at a relatively low cost (Yudha et al., 2019). Thus, lithium, nickel, manganese, cobalt battery (NMC type) with high nickel content has become predominant in the market ( Tahir et al., 2021 ).
The LIBs manufactured at the KIT, especially at the BTC, are mainly pouch cells. Thus, this work is dedicated to the energy and material flows of a pouch cell. The analyzed battery is a "KIT 20" cell with a rated capacity of 20 Ah, a nominal voltage of 3.7 V, and a gravimetric energy density of 141 Wh∙kg −1.
Lithium-ion batteries (LIBs) are being improved for such use due to their high energy per unit mass output. Manufacturing of LIBs should emphasize optimizing the performance of the battery. The processes in battery manufacturing are (1) electrode preparation, (2) battery assembly, and (3) cell formation.
