Abstract

Sodium-ion batteries (SIBs) have garnered significant attention due to their abundant resources and cost advantages. Hard carbon (HC) is considered one of the most promising anode materials for SIBs. However, irreversible sodium loss caused by the unique structure of hard carbon leads to a very low initial Coulombic efficiency (ICE) in SIBs. Pre-sodiation technology can effectively enhance battery performance by pre-supplementing sodium ions into the electrode material. This review systematically examines pre-sodiation strategies for SIBs with hard carbon as the anode material, discusses the key challenges faced by pre-sodiation technology in industrialisation, and explores the future direction of pre-sodiation technology. This review aims to provide researchers with a comprehensive understanding of pre-sodiation strategies and offer theoretical insights for developing efficient, industrially compatible pre-sodiation technologies for SIBs.

硬碳阳极钠离子电池的预钠化策略：技术、挑战和未来方向

钠离子电池因其丰富的资源和成本优势而备受关注。硬碳（HC）被认为是极具潜力的sib负极材料之一。然而，由于硬碳的独特结构导致的不可逆钠损失导致sib的初始库仑效率（ICE）很低。预钠化技术通过在电极材料中预补充钠离子，可以有效地提高电池的性能。本文系统地研究了以硬碳为阳极材料的sib的预固化策略，讨论了预固化技术在工业化中面临的主要挑战，并探讨了预固化技术的未来发展方向。本文旨在为研究人员提供对预调解策略的全面了解，并为开发高效、工业兼容的sib预调解技术提供理论见解。

期刊介绍： The journal provides an international medium for the publication of theoretical and experimental studies and reviews related to the electronic, electrochemical, ionic, magnetic, optical, and biosensing properties of solid state materials in bulk, thin film and particulate forms. Papers dealing with synthesis, processing, characterization, structure, physical properties and computational aspects of nano-crystalline, crystalline, amorphous and glassy forms of ceramics, semiconductors, layered insertion compounds, low-dimensional compounds and systems, fast-ion conductors, polymers and dielectrics are viewed as suitable for publication. Articles focused on nano-structured aspects of these advanced solid-state materials will also be considered suitable.
