| Abstract | Hollow SnO2 microspheres were synthesised through a hydrothermal process with post-calcination in air. Compared with commercial SnO2 nanoparticles, this organised and hollow SnO2 microspheres show a 3.3–3.6 times higher charge/discharge capacity, a superior cycling stability and a higher Coulomb efficiency when used as an anode material for sodium ion batteries (SIBs). The superior performance of hollow SnO2 microspheres was mainly attributed to the hollow structure with number of smaller nanoparticles. Compared with the disordered commercial SnO2 nanoparticles, the organised and hollow SnO2 microspheres with mesopores and micropores not only can facilitate charge transfer between the electrode and electrolyte, improve electronic and ionic transports, but also can accommodate the volume change to enhance the cycling stability of SnO2-based SIB anodes. This work also demonstrates that the unique hollow structures can be broadly used to construct electrode nanomaterials. |

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.
