A KIER analysis workforce led by Dr. Yu-Jin Han and Dr. Sang-Hoon Park has developed a core expertise to refine industrial graphite byproducts into high-purity anode supplies for lithium-ion batteries, a breakthrough that might significantly reduce reliance on imported graphite.
Graphite, the important uncooked materials for lithium-ion battery anodes in electrical automobiles, makes up about 30% of cell weight and 10% of manufacturing price. But Korea depends on China for over 90% of its provide, creating dangers of value surges and unstable availability amid world uncertainties.
Uncertainty turned evident final July, when the U.S. Division of Commerce imposed steep tariffs on Chinese language graphite utilized in anode supplies, heightening considerations about future provide stability.
In response, the workforce developed a core expertise to rework home industrial byproducts into high-value anode supplies. Their new impurity-removal methodology simplifies typical steps and allows the manufacturing of graphite anodes with price competitiveness on par with industrial supplies. The analysis is printed within the Chemical Engineering Journal.
Producing high-purity anodes from graphite byproducts requires the whole elimination of metallic impurities. Present strategies depend on harsh acid remedy and warmth processing above 2,000 °C, resulting…
