Special Issue Information

Dear Colleagues,

Secondary batteries are rechargeable batteries that transform electrical energy into chemical energy and vice versa. These batteries are widely deployed in a wide range of applications, from miniaturized devices to high-power-driven electric vehicles. Since the inception of Li-ion batteries, remarkable progress has been made to meet the needs of the energy-starving world. However, the popular Li-ion batteries have reached a limit in their energy density and power density. Therefore, the latest developments in the other secondary-type batteries have drawn the scientific community's attention. These advancements allow inexpensive and efficient energy storage solutions. The current Special Issue aims to present and disseminate the most recent advances in battery science and engineering, the chemistry of the secondary batteries, and novel electrode and electrolyte configurations.

The scope of publication includes, but is not limited to, the following: the latest advancements in Li-ion battery, Li–S battery, Li-air battery, all-solid-state battery, redox flow battery, Na-ion battery, Li–CO2 battery, and battery waste and recycling.

Li–S batteries are promising large-scale energy storage systems but currently suffer from performance issues; a major reason is the dissolution of polysulfides in electrolytes. To this end, we report a high-energy-density Lithium–Sulfur (Li–S) battery that combines a catholyte and a sulfur-free carbon nanofiber (CNF) cathode. The cathode was synthesized by carbonizing binder-free polyacrylonitrile (PAN) nanofibers, affording a high surface area. In the catholyte, added polysulfides acted as both conductive Li salts and active materials. Investigating the electrochemical performance of this concept in both Swagelok- and pouch-type cells afforded energy densities exceeding 3 mAh cm−2 at a discharge rate of 0.1 C. This combination could also be utilized in high-capacity pouch cells with capacities of up to 250 mAh g−1. Both cell types exhibited good cycle performance. Adding LiNO3 to the electrolyte suppressed the redox shuttle reactions. Moreover, the cathode being binder-free increased the energy density and simplified cathode fabrication. Characterizing the cathode before and after cycling revealed that deposition was reversible, and that cell reactions at least partially formed sulfur as the end product, resulting in high sulfur amounts in the cell. We expect our concept to greatly aid in the development of practically applicable Li–S cells. Full article
