Special Issue Information

Dear Colleagues,

Breakthroughs in energy storage technology are profoundly changing the world's energy landscape, the consensus being to develop a modern energy system based on renewable energy. With the strong momentum of electrochemical energy storage devices towards the efficient use of energy in mobile and stationary applications, metal batteries play a critical role in the era of electrification and are predicted to grow with the further penetration of renewable energy into the energy market.

The main prerequisite for the future success of metal batteries is further improvements of existing and the development of novel design philosophies. In addition, the synthesis and characterization of novel electrodes and electrolytes are key factors for the rapid development of metal batteries. Therefore, a state-of-the-art summary of the design, synthesis and characterization of metal batteries is very important.

This Special Issue of Metals entitled “Design, Synthesis and Characterization of Metal Batteries—State-of-the-Art” welcomes original research articles and reviews. The papers presented in this Special Issue should provide an account of the scientific and technological state-of-the-art of metal batteries. Research areas may include (but are not limited to) the following: the design, synthesis and characterization of electrodes and electrolytes for lithium ion batteries, sodium ion batteries, potassium ion batteries and aluminum batteries. Your contribution to this Special Issue is highly valuable and appreciated, and, thus, we invite you to contribute your research work concerning the mentioned theme. We look forward to receiving your contributions.

As an important component that affects the storage performance of sodium-ion batteries (SIBs), novel anode materials still need to be well explored. Herein, CoS1.097@C core–shell fibers as anode material were designed via coaxial electrospinning, stabilization, and carbonization. Specially, CoS1.097 powders are distributed in the inner shell of carbon fibers, and sufficient pore spaces are present among themselves. The unique encapsulation structure, porous characteristics, and one-dimensional conductive carbon shell can enable the CoS1.097@C core–shell fibers’ high initial specific capacity, excellent rate capability, and long cycle life. The initial charge and discharge capacities of the electrode at 50 mA g−1 are 386.0 and 830.9 mAh g−1, respectively. After 2000 cycles at 500 mA g−1, the discharge capacity is 216.3 mAh g−1. Even at 3000 mA g−1, the rate capacity can be maintained at 83.3 mAh g−1. Full article

Potassium-ion batteries with carbon-based materials and alloy materials as anodes possess pronounced potassium storage and cycling abilities, yet they suffer from harsh synthetic processes, low initial Coulombic efficiency, and limited structure stability. Herein, we first put forward potassium vanadium fluorophosphate (KVPO4F) as a highly stable anode material for potassium-ion batteries (PIBs). KVPO4F@C composite is successfully synthesized through hydrothermal method followed by a low-temperature roasting process. An amorphous carbon film is homogeneously wrapped on the surface of the KVPO4F particles to improve electronic conductivity. As the anode for PIBs, the KVPO4F@C presents a super-high discharge capacity of 242.32 mAh g−1 and a superior cycle stability over 120 cycles at 100 mA·g−1 with 93.1% capacity retention. Additionally, it maintains 92.9% of its initial capacity of 100 mA·g−1 at 1000 mA·g−1 after cycling 2100 times, which indicates an excellent long cycling performance. The in situ X-ray Diffraction and ex situ Transmission Electron Microscopy tests prove the minimal volume variation and stable structure of KVPO4F@C. The designed KVPO4F@C provides facilitative electronic conductivity and stable structure, successfully innovating an ultra-stable and high-performance anode material for potassium-ion batteries and other energy storage application fields.
