| Abstract | Despite the recent advancements in iron molten air batteries, great challenges still remain to realize cycling stability, high energy efficiency and a long-term cycling life. Herein, we demonstrate a new iron molten air battery for large-scale energy storage. We replace the KCl–LiCl–LiOH eutectic electrolyte used in our previous study with a Li0.87Na0.63K0.50CO3 eutectic electrolyte with added NaOH and LiOH. A fin air electrode configuration is designed to improve the coulombic efficiency. Cycling tests for the iron molten air battery showed a stable performance through 450 cycles with nearly 100% coulombic efficiency and an average discharge potential of ∼1.08 V when charged at a constant current of 0.05 A and discharged over a constant 100 Ω load to a 0.7 V cutoff at 500 °C. Moreover, the iron molten air battery had an excellent high-rate response up to 6.4C with a high coulombic efficiency of 95.1%. These results provide critical advances in developing iron molten air batteries with high efficiency and a long-term service life. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
