SPST Professor Publishes Lithium Battery Review


School of Physical Science and Technology Assistant Professor Liu Wei’s research group recently published a review tilted “Practical challenges and future perspectives of all-solid-state lithium metal batteries” in the internationally famous journal Chem.

As energy storage devices, lithium-ion batteries have become fundamental building blocks of modern society for their high energy density, superior cycling stability and light weight. However, state-of-the-art lithium-ion batteries cannot satisfy the increasing demand for higher energy density in large-scale energy storage applications. As a result, with new chemistries of both electrode and electrolyte materials, advanced lithium-based batteries with higher energy density, longer cycle life and higher safety should be developed urgently. Particularly, developing all-solid-state lithium metal batteries is a hot research topics. The application of solid state electrolytes by replacing liquid electrolyte in the lithium batteries could fundamentally eliminate the safety concerns. However, the sluggish Li-ion transport of solid state electrolytes as well as the high impedances at the solid-state electrolytes and electrode interface are the main factors impeding the commercialization process of all-solid-state lithium metal batteries.

The authors review the most recent progress and well-developed strategies to address the sluggish Li-ion transport of solid state electrolytes as well as the high impedance at the solid-state electrolytes/electrode interface. Furthermore, they give an overview of the recent advances and critical challenges for all-solid-state lithium metal batteries based on Li-intercalation compounds, sulfur and oxygen cathode share prospects of their future developments for next-generation energy storages. This review provides valuable reference for the commercialization of all-solid-state lithium metal batteries.

Postdoc Xia Shuixin of Liu group is the first author and undergraduate Wu Xinsheng is the co-first author. Assistant Professor Liu Wei and Adjunct Professor Cui Yi are the corresponding authors. ShanghaiTech University is the first responsible institution.
