Research progresses in O3-type Ni/Fe/Mn based layered cathode materials for sodium ion batteries

Abstract

Sodium ion batteries (SIBs) have attracted great interest as candidates in stationary energy storage systems relying on low cost, high abundance and outstanding electrochemical properties. The foremost challenge in advanced NIBs lies in developing high-performance and low-cost electrode materials. To accelerate the commercialization of sodium ion batteries, various types of materials are being developed to meet the increasing energy demand. O3-type layered oxide cathode materials show great potential for commercial applications due to their high reversible capacity, moderate operating voltage and easy synthesis, while allowing direct matching of the negative electrode to assemble a full battery. Here, representative progress for Ni/Fe/Mn based O3-type cathode materials have been summarized, and existing problems, challenges and solutions are presented. In addition, the effects of irreversible phase transitions, air stability, structural distortion and ion migration on electrochemical performance are systematically discussed. We hope to provide new design ideas or solutions to advance the commercialization of sodium ion batteries.

Designing low-strain cathode materials for long-life all-solid-state batteries

“…40 Additionally, we delve into the mechanical properties of CAMs within cathode composites, highlighting their critical relevance to the electrochemical performance of ASSBs during the insertion and extraction of lithium ions. 41 Finally, the review culminates with a brief summary and outlines potential avenues for future research on low-strain CAMs with high energy and mechanically optimized ASSBs that need a minimum stack pressure for stable long-term operation.…”

Suppression of Adverse Phase Transition of Layered Oxide Cathode via Local Electronic Structure Regulation for High-Capacity Sodium-Ion Batteries

“…Sodium-ion batteries (SIBs), a candidate for the future energy storage system, have been extensively investigated due to the abundant sodium resources and lower cost, offering a potential solution to the resource scarcity issues associated with lithium-ion battery (LIB) technologies. − However, a prominent challenge encountered by SIBs in their practical applications lies in their comparatively lower energy density than the LIBs, presenting a constraint that limits their market competitiveness. , …”

Ni-rich layered cathodes in sodium-ion batteries: perspectives or déjà vu?

“…3 Besides, many previous reviews extensively discussed the progress and trends on layered oxides for SIBs. For instance, some recent works summarize progress towards specific phases and compositions as cathodes for SIBs such as P2-Na 2/3 Ni 1/3 Mn 2/3 O 2 , 6 O3-type Na x Ni y Fe z Mn 1− y − z O 2 , 7 NaNi x Mn y Co z O 2 , 8 etc. On the other hand, many other comprehensive reviews highlight recent research, development, challenges, and strategies toward the practical application of NaTMO cathodes for SIBs.…”
