## Summary

The demand for mobile devices, electric vehicles, and energy storage systems is driving the rapid expansion of the battery market. As a result, there is a need to develop beyond Li-ion batteries that can adapt to the specific requirements of each application. This review-study by A. El Kharbachi et al. explores some of the relevant post-Li ion issues and battery technologies that are crucial in following these multiple-speed changes. The study discusses several alternative battery technologies such as Na-ion batteries, Mg batteries, Ca-ion batteries, Zn-ion batteries, Al-ion batteries and anionic (F- and Cl-) shuttle batteries. The authors also present MH-based batteries with emphasis on NiMH batteries and novel MH-accommodated Li-ion batteries. Furthermore, the study highlights future research trends and directions based on a comparison of different battery systems with respect to Li-ion battery assumptions. The authors note that aqueous systems are likely to be reconsidered for intensive, cost effective and safer production of batteries which could be utilized in (quasi)-stationary energy storage applications. Overall, this review study provides valuable insights into current developments in the field of battery technology beyond Li ion. It offers an excellent resource for researchers working on developing new battery technologies that can meet the demands of emerging applications while being cost effective and safe for use.
