Although there are some prototype FBs exhibited by the industry and a rapidly increasing number of publications reported by the academia, most demonstrations are shown on a laboratory scale, and it is still difficult to find real implementation of the technology in the market. This Perspective aims to discuss and analyze the key metrics, including energy density, flexibility, and safety, that is critical to pushing the FBs to a commercially viable level, with a special focus on the lithium batteries and zinc batteries that are mostly reported in the literature. We first compare the figure of merit of flexible batteries (fbFOM) of existing lithium-based and zinc-based FBs with the requirement with market applications. We then analyze the most desired cell configurations towards high flexibility, followed by systematic discussions on features and materials selection towards high-energy-density FBs. Third, we discuss strategies to enhance battery safety. An outlook of the future developments needed to address the gaps between the state-of-the-art demonstrations and the real applications is provided at the end of this article.
