Comparative Studies on Graphite and Hard Carbon Negative Electrodes for Alkali Metal-Ion Batteries Using FSA-Based Ionic Liquids

摘要

Most of the non-renewable energy resources such as coal and petroleum being used all over the world, are causing serious problems of climate change. Thus, the need of the hour is to reduce the usage of these resources and increase that of renewable ones, which is realized by bringing energy storage devices into picture. Batteries are the potential candidates of energy storage devices. The development of lithium-ion battery (LIB) revolutionized the electronic industry and has impacted the vehicle industry. Although LIBs are predominant choices for many applications in day to day life, the depletion of cobalt and lithium resources is a matter of growing concern. In order to mitigate the concern, we need to find alternatives for LIBs. One of the promising ways to fulfill such demands is to analyze the practical use of other alkali metal-ion batteries, such as Na-ion battery (NIB) and K-ion battery (KIB).
