| Abstract | Microporous carbon materials with specific surface area as high as 2352 m2 g−1 were synthesized by the carbonization of KOH-pretreated partially carbonized water bamboo at 800 °C under a N2 atmosphere for supercapacitor application. In particular, the carbon materials synthesized at a 2 : 1 weight ratio of KOH and pre-treated carbon exhibited excellent performance with a maximum specific capacitance of 268 F g−1 at a current density of 1 A g−1 in 6 M KOH electrolyte and retained up to 222 F g−1 even at a current density of 10 A g−1. In addition, this material also showed a good capacity retention of 97.28% over 5000 cycles at a current density of 10 A g−1. The excellent electrochemical properties could be due to their high specific surface area, abundant pore volume, appropriate pore size distribution and some oxygen groups. |

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.
