| Abstract | Ferroferric oxide, Fe3O4, is a highly promising anode material for lithium-ion batteries (LIBs) owing to its excellent electrochemical properties. High resolution transmission electron microscopy (HRTEM) was used to correlate the morphological features of the Fe3O4 nanoparticles (NPs) with their electrochemical properties. The co-precipitately synthesized Fe3O4 NPs were composed of 14-facet truncated octahedrons containing 6 {100} and 8 {111} planes, and 26-facet polyhedrons containing 6 {100}, 12 {110} and 8 {111} planes, indicating that the shape of NPs is changeable from 14-facet truncated octahedrons to 26-facet polyhedrons. As the anode for LIBs, the NPs delivered a high initial discharge capacity of 1067 mA h g−1, which could be attributed to their small size and abundant exposure of edges and corners in the multi-faceted polyhedral structures, offering low-coordinated atoms that act as active sites for lithium storage. |

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.
