Lithium slurry flow cell, a promising device for the future energy storage

Lithium slurry flow cell (LSFC) is a novel energy storage device that combines the concept of both lithium ion batteries (LIBs) and flow batteries (FBs). Although it is hoped to inherit the advantages of both LIBs and FBs, such as high energy density, ease of fabrication, environmental friendly, independent energy and power density, to name but a few. While unfortunately, it still has many challenges to overcome before it becoming the future star in energy storage area. Here in this paper, we briefly recall its history and try to illustrate the main issues that hindering its research as well as application. As a typical interdisciplinary product, LSFC is definitely a promising candidate for large scale energy storage application, while obviously it still has a long way to go.
