摘要

摘要基于硬碳负极材料的重点研究领域的电池,和bio-hard碳是最重要的材料之一。本研究以入侵物种互花米草为原料，掺杂纳米石墨制备高性能阳极材料。其第一库仑效率可达67%，比未掺杂纳米石墨的互花米草提高近10%。在20ma g−1电流下，比容量接近300ma h g−1。通过比较，我们发现经改性的互花米草具有很大的储钠能力，研究也证明了互花米草材料可以改性为具有较高经济价值的高性能阳极材料。

Nano graphite-doped Spartina alterniflora-based hard carbon as high performance anode for sodium-ion batteries

Abstract Anode materials based on hard carbon are the focus of research in the field of batteries, and bio-hard carbon is one of the most important materials. In this study, we use the invasive species Spartina alterniflora as raw material and doped with nano-graphite to produce high-performance anode materials. It can achieve a first coulomb efficiency of 67%, which is nearly 10% higher than Spartina alterniflora without nano-graphite doped. The specific capacity is close to 300 mA h g−1 under the current of 20 mA g−1. By comparison, we found that the modified Spartina alterniflora has great sodium storage capacity, and the study also proved that Spartina alterniflora material can be modified into a high-performance anode material with high economic value.
