Are high-purity cathode materials truly necessary? An alternative to reduce secondary battery costs

Managing the level of magnesium impurity purification emerges as a pivotal process in regulating secondary battery cathode material productivity, longevity, and eco-friendliness. Credit: POSTECH

Manufacturers of secondary battery cells (LG Energy Solution, Samsung SDI, and SK) have been insisting on very stringent purity specifications from suppliers of cathode materials to ensure a consistent quality output.

The purity specifications for cathode materials have been closely guarded as trade secrets, with little active scrutiny on the necessity of such high specifications. In response to the demands of cell manufacturers, suppliers of cathode materials have been investing significantly in purifying raw metals, consequently …
