Recent Progress and Prospects on Sodium-Ion Battery and All-Solid-State Sodium Battery: A Promising Choice of Future Batteries for Energy Storage

Abstract

At present, in response to the call of the green and renewable energy industry, electrical energy storage systems have been vigorously developed and supported. Electrochemical energy storage systems are mostly comprised of energy storage batteries, which have outstanding advantages such as high energy density and high energy conversion efficiency. Among them, secondary batteries like lithium batteries, sodium batteries, and lead-acid batteries have received wide attention in recent years. Lithium-ion batteries (LIBs) have existed for a long time. However, due to limited lithium resources worldwide, uneven distribution, and worrying safety issues, the development of LIBs has been gradually hindered. Meanwhile, sodium-ion batteries (SIBs), whose working principle is similar to that of LIBs, have been gradually emphasized by researchers due to the advantages of abundant resources and low cost. Moreover, all-solid-state sodium batteries (ASSBs), which have higher energy density, simpler structure, and higher stability and safety, are also under rapid development. Thus, SIBs and ASSBs are both expected to play important roles in green and renewable energy storage applications. This Review focuses mainly on the detailed introduction of the constituent materials of SIBs and ASSBs, analyzing the development of cathode and anode materials and the solid-state electrolytes (SSEs) in the past five years. The advantages and development direction of each SSE suitable for ASSBs are listed and remarked, and the nonactive materials such as separators and collectors are briefly mentioned. Finally, a reasonable assessment and prospects of the different materials and preparation methods are put forward.

Perspective on Phase Transition in Layered Oxide Cathodes for Sodium-Ion Batteries: Mechanism, Influenced Factors, and Inhibition Strategies

“…The preceding discussion has underscored the multiple factors influencing phase transitions, thus it is highly reasonable to tailor strategies for suppressing phase transitions based on these influences. Element doping is an effective strategy, which is often considered the most efficient method for suppressing phase transitions as it fundamentally alters the intrinsic properties of the material. For instance, it can modulate the material’s electronic structure, charge/ion state, energy band structure, and crystal structure to enhance structural stability and suppress phase transitions .…”

Review and Perspectives on Preparation Strategies and Applications of Ti3C2 MXene for Li Metal Batteries/Li–S Batteries

“…MXene, as a novel two-dimensional material, has widely used in the field of energy storage. Many researchers have described it. − But the most review papers only describe one metal battery or the preparation methods about MXene are very rough, which means that it is difficult for reader to master the other metal batteries and the preparation methods about MXene. − Moreover, some review articles have been published by scholars, covering many fields such as electrocatalysis, sodium ion batteries and all solid-state sodium batteries, supercapacitors. − However, there is little work about MXene, such as MXene-based supercapacitor, which means it is difficult for readers to grasp the application of MXene in metal batteries and the preparation methods of MXene. On the contrary, this review paper provides a detailed introduction to six preparation methods of MXene, such as HF etching, HCl and LiF etching, molten salt etching, electrochemical etching, deep eutectic solvent assisted etching, and alkaline etching, and presents the characteristics of these preparation methods and precursor MAX.…”
