Metal–iodine batteries (MIBs) are becoming increasingly popular due to their intrinsic advantages, such as a limited number of reaction intermediates, high electrochemical reversibility, eco-friendliness, safety, and manageable cost. This review details past attempts and breakthroughs in developing iodine cathode-based (rechargeable) metal battery technology, to arrive at a comprehensive discussion and analysis of the battery's working mechanisms and fundamental challenges. Especially, the realization of available rechargeable MIBs relies heavily on the joint action of the battery components. We therefore cover here the progress starting from electrodes, electrolytes, and separator/interlayer requirements to introduce various types of MIBs and finally a critical analysis of the status quo, allowing us to gain insight into the roadblocks that still exist in MIBs. Also, we collect and compare the electrochemical performance of MIBs by category with listing their actual active material loading species and cell fabrication parameters. Finally, we conclude with recommendations for future strategies to leverage current advances in battery engineering, characteristics, and computational designs, all of which enable MIBs to reach their full potential in the energy age ultimately.

Energy & Environmental Science
Energy & Environmental Science is an international journal dedicated to publishing exceptionally important and high quality, agenda-setting research tackling the key global and societal challenges of ensuring the provision of energy and protecting our environment for the future. The scope is intentionally broad and the journal recognises the complexity of issues and challenges relating to energy conversion and storage, alternative fuel technologies and environmental science. For work to be published it must be linked to the energy-environment nexus and be of significant general interest to our community-spanning readership. All scales of studies and analysis, from impactful fundamental advances, to interdisciplinary research across the (bio)chemical, (bio/geo)physical sciences and chemical engineering disciplines are welcomed. Topics include, but are not limited to, the following: Solar energy conversion and photovoltaics Solar fuels and artificial photosynthesis Fuel cells Hydrogen storage and (bio) hydrogen production Materials for energy systems Capture, storage and fate of CO2, including chemicals and fuels from CO2 Catalysis for a variety of feedstocks (for example, oil, gas, coal, biomass and synthesis gas) Biofuels and biorefineries Materials in extreme environments Environmental impacts of energy technologies Global atmospheric chemistry and climate change as related to energy systems Water-energy nexus Energy systems and networks Globally applicable principles of energy policy and techno-economics
