Abstract
P2-type Na2/3Ni1/3Mn2/3O2 (NNM), a promising candidate cathode material for advanced sodium ion batteries, has been extensively investigated in terms of its excellent electrochemical performance, straightforward preparation process, cost-effectiveness, and similarities to well-established Li-ion counterparts. However, the specific capacity, rate capability and cycling stability are severely dragged down by irreversible phase transitions, Na+/vacancy ordering, and interface deterioration. Research progress related to modification strategies for boosting the performance of P2-NNM cathodes in SIBs is provided. The perspectives and development directions for the optimization strategies for NNM cathodes are also presented. This review systematically and comprehensively elaborates the modification strategies for NNM cathodes, furnishing a positive guideline for designing and optimizing P2-NNM cathodes for the burgeoning commercial SIBs market.
期刊介绍：
Sustainable Materials and Technologies (SM&T), an international, cross-disciplinary, fully open access journal published by Elsevier, focuses on original full-length research articles and reviews. It covers applied or fundamental science of nano-, micro-, meso-, and macro-scale aspects of materials and technologies for sustainable development. SM&T gives special attention to contributions that bridge the knowledge gap between materials and system designs.
