摘要:

全固态锂电池具有优异的安全性能和能量密度,有望成为替代传统有机液态锂离子电池的下一代储能产品。固态电解质是决定全固态电池性能的关键材料,其中卤化物固态电解质,尤其是稀土溴化物固态电解质(RE-BSEs)材料近年来在离子电导率(高达mS/cm数量级)和电化学稳定性(1.5~3.4 V vs.Li+/Li)等方面取得了一系列重要的研究进展,具有可期待的应用前景。本文通过对RE-BSEs的发展历程、研究进展、技术瓶颈、发展方向和应用前景等方面进行综述和回顾,给予研究人员在RE-BSEs的合成方法、锂离子传输机理、构效关系和材料设计等方面的参考和启发。稀土是我国乃至世界的重要战略资源,RE-BSEs材料的研究和重要成果明示了稀土元素在固态离子导体和新能源领域的重大价值,因此,做好稀土在该方面的研究工作对能源结构调整、节能减排、碳达峰和碳中和具有重大意义。

Abstract:

All-solid-state lithium-ion batteries possess excellent safety performance and high energy density, and are expected to be the next generation energy storage devices to replace traditional liquid batteries. Solid-state electrolytes are definitely the key materials to achieve the real all-solid-state batteries. In recent years, considerable progress has been made in halide electrolytes, especially rare earth-containing bromide based solid electrolytes (RE-BSEs), which show good ionic conductivities (up to mS/cm order of magnitude), electrochemical stability (1.5~3.4 V vs.Li+/Li) and so on. In this article, we review the research advances focusing on the possible applications and technical bottlenecks of RE-BSEs. Hopefully, it may be enlightening and spark some inspirations in terms of synthetic strategies, lithium ion transportation mechanism, and investigating methodologies in the study of RE-BSEs. Rare earth is one of the most important strategic resources of China and even for the world. The research and important achievements made on RE-BSEs show the high value potentials of rare earth elements, especially in fields of solid ionics and energy saving and conversions. It is of great significance for structural adjustment of energy economics, and will contribute to the emission peak and carbon neutrality.

Key words: Rare earth, Bromide, Solid electrolyte, All solid state battery
