Abstract

Abstract: Research and development of advanced rechargeable battery technologies is dominated by application‐specific targets, which predominantly focus on cost and performance targets, including high gravimetric energy, volumetric energy, and related power densities, while ensuring a high safety and long lifetime. The need for high‐performance and low‐cost batteries is driven by the growing market of electromobility, in order to fulfill key requirements, such as a sufficient driving range and fast charging ability, for achieving broad consumer acceptance. Currently, the lithium ion battery (LIB) is one of the state‐of‐the‐art technologies able to meet most of these key requirements at a reasonable cost. In addition to performance and costs, the environmental impact, i.e., the sustainability of the battery and in particular of the battery cell over the whole life cycle—i.e., from raw material extraction and battery material production, to cell and battery pack production, battery utilization, and to possibilities for second life usage and recycling—does receive continuously increasing attention. Within this review, different approaches for the development of "greener" batteries are introduced with a view on the complete battery life cycle, while focusing on the LIB technology. Moreover, alternative battery technologies are critically evaluated regarding their sustainability aspects and competitiveness. Abstract : The continually increasing consumption of energy and scarce raw materials for the global growth of battery production raises concerns about the carbon footprint and the sustainability of current battery technologies and materials. New material approaches, improved production and recycling processes, as well as novel battery chemistries can offer a greener solution for future energy storage devices.
