| Abstract | A SnO$_{2}$−RuO$_{2}$ composite (SnRuO) thin film possesses unique electrochemical properties for a hybrid between batteries and supercapacitors due to the fact that the SnRuO system shows battery and supercapacitor characteristics simultaneously. SnRuO thin films were prepared through the magnetron co-sputtering method in order to investigate the feasibility of a monolithic thin film hybrid battery. The SnRuO thin film as an anode film for a secondary battery demonstrated a first discharge capacity of 1557 μAh/cm$^{2}$·μm; the second discharge capacity was 52% of the first discharge capacity. The degree of capacity fade of the SnRuO thin film was almost the same as that of the SnO$_{2}$ thin film, even though the capacity of the SnRuO thin film was larger than that of the pure SnO$_{2}$. In addition, the SnRuO thin film showed a supercapacitor behavior and exhibited a specific capacitance of 14 mF/cm$^{2}$ μm during 1000 cycles. These results suggest that SnRuO thin film could be used as a thin film supercapacitor as well as a thin film battery. Furthermore, this composite thin film holds promise for the fabrication of a monolithic thin film high power hybrid battery based on micro-processes. |

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.
