摘要：

普通锂离子电池在高电压下的氧化分解限制了高压锂离子电池的发展，为了解决这一问题，可以设计、合成新型的耐高压电解液；寻找合适的电解液添加剂，然而从经济效益考虑，发展合适的电解液添加剂来稳定电极/电解液界面更加受到研究者们的青睐。本文综述了最近几年在高压锂离子电池电解液添加剂方面的研究进展，并按照添加剂的种类将其分为6部分进行探讨：含硼类添加剂、有机磷类添加剂、碳酸酯类添加剂、含硫添加剂、离子液体添加剂及其它类型添加剂。分别对这些添加剂的作用机理、作用效果进行了阐述，展望了添加剂在高压锂离子电池中的发展前景及未来研究方向。

Abstract:

The decomposition of traditional lithium-ion batteries at high voltage limit the development of high voltage lithium-ion batteries. Approaches to circumvent these challenges include (1) the design and synthesis of intrinsically stable electrolytes to tolerate high voltages, and (2) looking for suitable electrolyte additives. The latter approach is particularly appealing from the techno-economic perspective to stabilize the electrode/electrolyte interphase. This review summarizes the latest research progress on electrolyte additives for high voltage lithium-ion batteries. According to their types, the additives can be divided into six categories: boron-based additives, organophosphorus additives, carbonate additives, sulfur-based additives, ionic liquid additives, and other additives. The effect and working mechanism of the additives are generally described and discussed. The prospect of the high voltage electrolyte additives used in the future were also analyzed.
