摘要
沥青是原油蒸馏或煤炼焦加工过程中产生的较难处理的副产物,对其进行定向的、高效应用具有重要经济意义。目前沥青在锂离子电池负极材料领域已有相关的研究和应用,但其组成和结构复杂,基础性能与电化学性能的关联尚不明确导致应用受限。本文重点综述沥青基负极材料以及沥青作为改性负极在锂离子电池中的应用研究进展,并对沥青在新能源领域的专用开发与高效利用提供了新的研究思路和方法。
Pitch is a by-product produced in the process of crude oil distillation or coal coking,and its efficient application is important to realize the economic significance.Currently,pitch has been researched and applied in the field of anode materials for lithium-ion batteries.However,its composition and structure are complex,which induces an unclear relationship between basic properties and electrochemical performance,and leads to limited applications.This article focuses on reviewing the research progress of anode materials,which made or decorated by pitch for lithium-ion batteries,and provides new research ideas for the development and efficient utilization of pitch in the field of new energy.
