놀이터 먹튀 launched 놀이터 먹튀 Materials in 2018 in the Yeongilman Industrial Complex in Pohang, followed by 놀이터 먹튀 Innovation and 놀이터 먹튀 AP in October 2022. It has a complete battery cathode material ecosystem (eco-friendly closed-loop system) named 'EcoBattery Pohang Campus' with an area of about 150,000 square meters. 

'Closed Loop Eco-system' is 놀이터 먹튀's only battery cathode material value chain in Korea. Lithium hydroxide (놀이터 먹튀 Innovation), precursors (놀이터 먹튀 Materials), and high-purity oxygen and nitrogen (놀이터 먹튀 AP) are delivered to 놀이터 먹튀 BM and 놀이터 먹튀 EM to produce cathode materials. This is a circular system in which raw materials such as lithium, nickel, and cobalt are extracted and delivered to cell manufacturers, and when the batteries become waste batteries, they are collected and recycled by 놀이터 먹튀 CnG.The eco-friendly ecosystem of cathode materials created by 놀이터 먹튀 will now be joined by 놀이터 먹튀 HN, a comprehensive eco-friendly solution company. The enhanced eco-friendly system minimizes the generation of pollutants such as wastewater from the existing battery Cathode material ecosystem. In addition, by advancing recycling technology, the ratio of wasted water is kept close to 0% through the infinite circulation of polluted water.
