About this Research Topic
Widespread application of fossil fuels for energy generation and transportation purposes during the past few decades has dramatically increased the concentration of greenhouse gases in atmosphere, causing an unprecedented raise of the Earth’s temperature and acidification of the oceans. Therefore, there is an urgent need to reduce the devastating consequences of global warming, as highlighted in the Global Summit on Climate Change (Paris Agreement) as well as the European Commission. Replacing conventional fossil fuels with renewable sources of energy has been recognized as one of the crucial actions required. In this regard, a switch from internal combustion engines (ICE) to electric vehicles (EVs) has attracted great attention recently as the major portion of fossil fuels is consumed for transportation purposes.
The electric energy storage systems are at the center of universal application of renewable energy and electric transport. The revolutionary role of advanced batteries for energy storage in shaping our society was recognized by awarding the 2019 Nobel Prize in chemistry for developing the Li-ion battery technology. Li-ion battery systems have been state-of-the-art technology for energy storage in mobile applications including EVs. However, the available Li-ion technology cannot meet the requirements of the electrical transportation in terms of driving range, safety and cost. Therefore, developing new battery systems with higher energy density, enhanced performance and improved safety at lower cost is required. Several new battery systems have been extensively investigated in order to address the aforementioned challenges. This Research Topic covers some of these emerging systems – in particular, the energy storage systems beyond Li-ion intercalation systems. This Research Topic is focused on all fundamental aspects of advanced post lithium-ion energy storage systems including Na-ion, K-ion, multivalent ion-based, metal-sulfur and metal-oxygen batteries. We particularly welcome the submission of full research papers, reviews and short communications on the following themes:
- Design and development of cathode and anode electrodes for Na-ion and K-ion batteries
- Multivalent ion-based (Mg/Ca/Al/Zn-ion) batteries
- Alkali metal-chalcogen (Na/Li/K-S/Se/Te) batteries
- Metal-oxygen or air (Li/Na/K-O2/air, Mg/Ca-O2) batteries
Keywords: rechargeable batteries;, beyond intercalation;, post lithium-ion batteries;, 2D materials, nanomaterials
