About this Research Topic
Currently, there is only 170 GW of installed storage capacity around the world. The development of efficient, low-cost, and environmentally-friendly electrochemical storage systems is, therefore, fundamental for the future of the renewable energy economy.
Batteries are considered one of the key technologies that can enable the transition to a low-carbon economy through their deployment in mobility and stationary storage systems. The most mature modern battery technology is the lithium-ion battery (LIB), which is considered the most suitable battery for electromobility and for most of the electrochemical energy market because of the high energy density. Moreover, the alternative metal-ion battery (MIB) chemistries and concepts, e.g., batteries based on Na, Ca, Mg, Al, and Zn ions have motivated due to abundant, nonflammable, and non-critical elements. When these metals are directly used as an anode, a needle-like structure, called dendrite, forms on the surface in the process of charging and discharging. These structures provide poor cycling performance and reduce the coulombic efficiency (CE) through forming an undesired solid-electrolyte interface (SEI). Therefore, adopting appropriate strategies to construct a new type of structure for MIBs to alleviate short circuit and inhibit dendrite growth has become extremely critical to achieve safe and long-term stable batteries.
Solid-state batteries that replace liquid electrolytes with solid ionic conductors can effectively eliminate the drawbacks of flammability and interface instability of liquid electrolytes. Solid electrolyte, that is a vital part of a solid-state battery, is a good choice to build a solid and stable metal interface because of its thermal, chemical and electrochemical stability, mechanical strength, and adequate interface.
Given the advances and optimizations in the studies of batteries and the procurement of energy efficient vehicle solutions, the focus of this research topic is based on advanced batteries with high specific energy for electrical vehicles.
