生物质基多孔碳制备及其在锂硫电池中的应用（综述）
摘要
随着高效、经济的储能需求的增长，硫锂电池以其理论上的能量密度和成本效益成为下一代高能可充电锂电池的理想选择。我们从硫锂电池的发展史来了解锂离子电池的电化学特性，并讨论锂离子电池的电化学活性和多硫化物的溶解等问题。针对这些关键问题，简述锂离子电池的研究进展，包括S阴极，Li阳极、电解液以及具有无锂金属阳极的硫锂电池的新设计。构建限制在到点位孔碳材料中的硫分子，以提高锂电池的可循环性，是该行业未来的发展方向。

Preparation of Biomass-based Porous Carbon and Its Application in Lithium-Sulfur Batteries (Review)
ABSTRACT
With the increasing demand for efficient and economic energy storage, Li-S batteries have become attractive candidates for the next generation high-energy rechargeable Li batteries because of their high theoretical energy density and cost effectiveness. Starting from a brief history of Li-S batteries, this Review introduces the electrochemistry of Li-S batteries, and discusses issues resulting from the electrochemistry, such as the electroactivity and the polysulfide dissolution. To address these critical issues, recent advances in Li-S batteries are summarized, including the S cathode, Li anode, electrolyte, and new designs of Li-S batteries with a metallic Li-free anode. Constructing S molecules confined in the conductive microporous carbon materials to improve the cyclability of Li-S batteries serves as a prospective strategy for the industry in the future.
Keywords: electrochemical, electrolyte, lithium-sulfur battery
