Light metals have been widely used as electrode materials for batteries owing to their low standard redox potential, their low equivalent weight, large specific capacity, and great abundance. Both primary and secondary cells including light metals as electrode material have influenced all aspects of our lives, e.g., electrically operated toys, power tools, and portable electronics such as cell phones, smart pads, and laptop computers. Among all battery systems, rechargeable lithium (Li) ion cells have been used most widely in recent years owing to their high specific power, high energy density, and ambient temperature operation. However, Li‐ion cells are facing difficult challenges in satisfying the emerging market for advanced applications demanding high‐performance rechargeable batteries for applications such as electric vehicles, high‐performance portable electronics, and large‐scale electrical energy storage systems. Unfortunately, current Li‐ion cells cannot satisfy demands such as low cost, much improved safety, larger energy density, faster charge/discharge rates, and longer service life, so intensive effort is necessary to develop the next generation of cells. In this article, the limitations of current Li‐ion cells and various advanced materials for each component of the Li‐ion cell, in addition to other promising candidates for cells beyond Li ion, such as the Li/S cell and Na‐ and Mg‐based rechargeable cells, and metal/air cells are discussed.

“…Furthermore, sulfur, which is ubiquitous in nature, is environmentally benign and low-cost. [4,[8][9][10][11][12][13][14][15] Li/S cells have become one of the most promising rechargeable cell systems, showing great potential in meeting the rigorous needs for electrical vehicles and grid-scale stationary storage. Despite their advantages, Li/S cells still are affected by some intrinsic drawbacks.…”

TitleLi2S nano spheres anchored to single-layered graphene as a high-performance cathode material for lithium/sulfur cells b s t r a c tFully lithiated lithium sulfide (Li 2 S) has become a promising cathode material for Li/S cells due to its high theoretic capacity (1166 mA h g À 1 ) and specific energy (2600 W h kg À 1 ). However, low utilization of sulfur and poor rate capability still hinder the practical application of Li/S cells. In this paper, a carbon coated Li 2 S/graphene composite (Li 2 S/G@C) was developed by incorporating Li 2 S nano spheres with single-layered graphene and further forming a durable protective carbon layer on the surface of the Li 2 S particles using a facile CVD method. The high rate capability and remarkable cycle life of the Li 2 S/G@C cathode were demonstrated, which was mainly attributed to the unique structure of the Li 2 S/G@C that can significantly improve not only the electrical conductivity, but also the mechanical stability of the sulfur cathode.
