Sodium-ion batteries
Sodium-ion battery technology offers a promising alternative to lithium-ion systems with unique cathode and anode materials, emphasizing cost, stability, and performance in energy storage applications.

Sodium-ion batteries are electrochemical energy storage cells that substitute sodium ions for lithium as the charge-carrying species shuttling between cathode and anode during charge and discharge cycles, operating on insertion and extraction chemistry mechanistically analogous to lithium-ion but governed by sodium’s larger ionic radius, lower reduction potential, and substantially greater crustal abundance.

음극 소재 기술은 크게 세 가지 주요 계열로 나뉩니다.

  • 층상 전이 금속 산화물
  • 프러시안 블루 유사품
  • NASICON형 인산염 및 황산염을 포함하는 다음이온 화합물

각각은 특정 용량, 전압 평탄도, 반복적인 나트륨화에 따른 구조적 안정성 및 합성 비용 측면에서 뚜렷한 장단점을 나타내며, 어떤 단일 양극 화학 물질도 리튬 이온 시장에서 NMC와 LFP가 차지하는 것과 같은 시장 점유율을 확보하지 못했습니다.

양극 측면에서 흑연은 나트륨 삽입 능력이 매우 미미하여 부적합하며, 현재 실용적인 표준으로 바이오매스 또는 수지 전구체에서 유래한 경질 탄소에 대한 연구가 진행되고 있습니다. 나트륨 금속 양극은 더 높은 에너지를 제공하지만 덴드라이트 생성이 용이한 새로운 연구 분야입니다. 전해질 조성(에테르 또는 탄산염 용매에 용해된 NaPF6 또는 NaClO4 염, 이온성 액체, 또는 새롭게 개발되고 있는 고체 나트륨 전도체)은 초기 사이클 쿨롱 효율, 속도 성능 및 시간 경과에 따른 노화를 좌우하는 고체 전해질 계면 화학을 결정하는 데 매우 중요합니다.
