Emerging Chemistry for Wide-Temperature Sodium-Ion Batteries

Chemical Reviews, Год журнала: 2024, Номер 124(8), С. 4778 - 4821

Опубликована: Апрель 2, 2024

The shortage of resources such as lithium and cobalt has promoted the development novel battery systems with low cost, abundance, high performance, efficient environmental adaptability. Due to abundance cost sodium, sodium-ion chemistry drawn worldwide attention in energy storage systems. It is widely considered that wide-temperature tolerance batteries (WT-SIBs) can be rapidly developed due their unique electrochemical chemical properties. However, WT-SIBs, especially for electrode materials electrolyte systems, still face various challenges harsh-temperature conditions. In this review, we focus on achievements, failure mechanisms, fundamental chemistry, scientific WT-SIBs. insights design principles, current research, safety issues are presented. Moreover, possible future research directions WT-SIBs deeply discussed. Progress toward a comprehensive understanding emerging comprehensively discussed review will accelerate practical applications rechargeable batteries.

Entropy Tuning Stabilizing P2‐Type Layered Cathodes for Sodium‐Ion Batteries

Advanced Functional Materials, Год журнала: 2024, Номер 34(24)

Опубликована: Янв. 21, 2024

Abstract The P2‐type layered transition metal oxide cathodes confront formidable challenges, including irreversible deleterious phase transitions, metals migration, and sluggish Na + diffusion kinetics, which hamper their rapid commercial application in sodium ion batteries (SIB). In this work, an entropy tuning with dual‐site substitution strategy is proposed to address the aforementioned issues. tailored [Na 0.67 Zn 0.05 ]Ni 0.22 Cu 0.06 Mn 0.66 Ti 0.01 O 2 (NZNCMTO) cathodes, strategic incorporation of ions serves occupy sites, intentionally disrupting Na/vacancy ordering establishing a reinforcing “pillar” effect within framework. Furthermore, for Ni bolsters covalent bonding lattice oxygen, thereby impeding migration leading near‐zero strain structural evolution during charge discharge process. Density functional theory calculations confirmed that entropy‐tuned NZNCMTO substantially lowered energy barrier improved electronic conductivity. Consequently, cathode exhibits impressive high practical capacity 91.54 mAh g −1 at rate 10 C, along outstanding cycling stability, maintaining near 100% retention over 500 cycles current density C. This work presents innovative blueprint designing high‐performance sodium‐ion battery materials.
