基于生物质硬碳钠离子电池负极材料研究进展

Research Progress of Sodium Ion Batteries Anode Materials Based on Biomass Hard Carbon

  • 摘要: 随着可再生储能材料的深入研究,锂离子电池因具有比能量大、自放电小、绿色环保等优势而备受青睐。但是锂资源储量有限且分布不均,导致锂离子电池生产成本较高,频繁充放电缩减使用寿命,难以满足未来规模化应用的需求。为了解决上述问题,新型钠离子电池可作为传统锂离子电池的潜在替代品。阐述了硬碳材料的储钠机理,及生物质衍生硬碳负极的常用制备方法,并介绍了其在钠离子电池中的应用。

     

    Abstract: As a kind of renewable energy storage material, lithium ion batteries are preferred because of the advantages of large specific energy, small self-discharge and green environmental protection. However, due to the limited and unequal distribution of lithium resources, the lithium ion battery has a high cost and its life is shortened by frequent charging and discharging, which makes it difficult to meet the needs of future large-scale applications. In order to solve above problems, the new type of sodium ion battery can be used as a potential substitute for the traditional lithium ion battery. Here is mainly introduced the sodium storage mechanism of hard carbon materials, the preparation of biomass-derived hard carbon anodes by several common methods and their application in sodium ion batteries.
