| Abstract | Lithium-rich layered oxide 0.3Li2MnO3·0.7LiNi1/3Co1/3Mn1/3O2 nanorods have been prepared by a KCl molten salt-assisted template route. The nanorods can well retain the rod-like structure of a β-MnO2 template, and have the length of several hundred nanometres and diameters of about one hundred nanometres. In comparison with the sample obtained from immediate solid-state reaction, the molten salt treatment can help improve the phase purity and decrease the particle size. As a lithium-ion battery cathode, the KCl-treated nanorods deliver an initial discharge capacity of 242.9 mAh g−1 with a high Coulombic efficiency of 83.6% at a current density of 20 mA g−1 within 2.0–4.7 V. After 60 cycles, a discharge capacity of 150.8 mAh g−1 can be retained at 0.5 C. Even at a high charge–discharge rate of 4 C (800 mA g−1), a stable capacity of 104.2 mAh g−1 can be reached, while the sample obtained from solid-state reaction only delivers an initial discharge capacity of 179.1 mAh g−1at 20 mA g−1. |

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.
