O3-Type Layered Ni-Rich Oxide: A High-Capacity and Superior-Rate Cathode for Sodium-Ion Batteries.
Small. 2019 Dec; 15(52):e1905311.S

Abstract

Inspired by its high-active and open layered framework for fast Li+ extraction/insertion reactions, layered Ni-rich oxide is proposed as an outstanding Na-intercalated cathode for high-performance sodium-ion batteries. An O3-type Na0.75 Ni0.82 Co0.12 Mn0.06 O2 is achieved through a facile electrochemical ion-exchange strategy in which Li+ ions are first extracted from the LiNi0.82 Co0.12 Mn0.06 O2 cathode and Na+ ions are then inserted into a layered oxide framework. Furthermore, the reaction mechanism of layered Ni-rich oxide during Na+ extraction/insertion is investigated in detail by combining ex situ X-ray diffraction, X-ray photoelectron spectroscopy, and electron energy loss spectroscopy. As an excellent cathode for Na-ion batteries, O3-type Na0.75 Ni0.82 Co0.12 Mn0.06 O2 delivers a high reversible capacity of 171 mAh g-1 and a remarkably stable discharge voltage of 2.8 V during long-term cycling. In addition, the fast Na+ transport in the cathode enables high rate capability with 89 mAh g-1 at 9 C. The as-prepared Ni-rich oxide cathode is expected to significantly break through the limited performance of current sodium-ion batteries.
