Special Issue Information

Dear Colleagues,

The fast-paced development of science and technology has brought unprecedented advances to human society. The continued consumption of fossil fuels had led to the ever-growing demand for clean, renewable and sustainable energy source. Electrochemical energy storage systems have ushered in significant development opportunities. Among the various electrical energy systems, potassium ion batteries have been extensively explored due to their natural abundance and low cost of potassium resource, high security and environmental friendliness.

The main prerequisite for the future success of potassium ion batteries is further improvements properties of electrode materials. In addition, the new insights regarding the synthesis and characterization of new electrodes and electrolytes are the key factor of the rapid development of potassium ion batteries. Therefore, a state of the art summary of the new insights in potassium ion batteries: materials and properties is very important.

This Special Issue is entitled “New Insights in Potassium Ion Batteries: Materials and Properties”. In this Special Issue, original research articles and reviews are welcome. The papers presented in this Special Issue provide an overview of the new insights regarding potassium ion batteries about materials and properties. Research areas may include (but are not limited to) the following: the design, synthesis and characterization of electrode materials and electrolytes, and the modified properties of electrodes for potassium ion batteries. Your contribution to this Special Issue is highly valuable and appreciated. We invite you to contribute research work that explores the new insights in potassium ion batteries from a materials and properties perspective. We look forward to receiving your contributions.

Anode materials have a vital influence on the performance of sodium ion batteries. In this paper, SnSb nanoparticles were distributed uniformly in N-doped three-dimensional porous carbon (SnSb@N-PC), which effectively avoided the agglomeration of alloy nanoparticles and greatly improved the capacity retention rate of SnSb@N-PC. At the same time, the porous carbon substrate brings higher conductivity, larger specific surface area, and more sodium storage sites, which makes the material obtain excellent sodium storage properties. The first discharge-specific capacity of SnSb@N-PC was 846.3 mAh g−1 at the current density of 0.1 A g−1, and the specific capacity remained at 483 mAh g−1 after 100 cycles. Meanwhile, the specific capacity of SnSb@N-PC was kept at 323 mAh g−1 after 400 cycles at a high current density of 1.5 A g−1, which indicated that the recombination of SnSb with porous carbon played a key role in the electrochemical performance of SnSb. The contribution of capacitance contrast capacity was able to reach more than 90% by the cyclic voltammetry (CV) test at high sweep speed, and larger Na+ diffusivity was obtained by the constant current intermittent titration technique (GITT) test, which explains the good rate performance of SnSb@N-PC.
