Metal-ion batteries for electric vehicles: current state of the technology, issues and future perspectives
Jaya Verma, Deepak Kumar
Abstract
The batteries based on metals-ions have the potential to meet the future needs of electric vehicle (EV) applications. This article reviews the key technological developments and scientific challenges of a broad range of Li-ion, Mg-ion and Al-ion batteries for electric vehicles. The fundamental configurations and corresponding reaction mechanisms of metal-ion strategies are tangibly discussed in this review article. After a brief revision of the fundamentals, the performance is analysed among Li-ion, Mg-ion and Al-ion battery technologies. The key parameters for the present compilation are the abundance, the volumetric capacity, the gravimetric capacity, the cycling life, cost and safety. Further, it summarizes the recycling methodologies, strengths and limitations of these batteries. Finally, future directions of all these batteries are highlighted and discussed.
