| Abstract | Based on the structure of lithium-ion batteries (LIBs), the electrode materials were separated from spent LIBs with aim to recycle all valuable components as possible. The spent LIBs were dismantled first, then the mechanical pulverization and sieving process was adopted in the separation of anodes. Owing to low bonding force between graphite carbon particles and copper foil, graphite carbon can easily drop off and be separated when anode materials were struck. The results showed that after shredding and sieving, most copper was concentrated in the particle size above 0.59 mm (below 30 mesh), the copper recovery rate reached 93.10 wt %, and the content of copper was 95.40 % at the condition of 3 min pulverization. Further separation of the anode scraps from 0.590 mm to 0.177 mm was carried out using fluidized bed technology. Approximately 92.30 wt % of copper in anode particles from 0.590 mm to 0.177 mm can be recovered by a gas-fluidized bed separator at the selected optimal gas velocity (1.00 $m·s^{−1}).$ |

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.
