삼성SDI가 월요일 서울에서 메르세데스-벤츠 그룹과 다년간의 전기차(EV) 배터리 공급 계약을 체결했다. 이는 양사 간 첫 EV 배터리 거래로, 최신 세대 EV에 고성능 NCM 배터리를 공급한다. 양사는 차세대 배터리 기술 공동 개발 등 미래 모빌리티 분야 협력을 확대하기로 했다.

Used batteries from electric vehicles could fulfill two-thirds of China's grid storage requirements by 2050, according to a study by researchers at Tsinghua University. These second-life batteries would charge during periods of abundant renewable energy and release power during peak demand. The approach could reduce costs by 2.5 percent while supporting a shift to carbon-neutral power systems.
