Project Description

Due to the high impact of energy storage devices for biological/medical devices (pacemaker, hearing aid, in vivo imaging, etc.) and self-powered microelectronics (miniature transmitters, sensors, actuators, etc.) on economics and society, the development of new materials for such applications has strong social impact providing development and availability of healthcare devices, enhancement of security and safety, rising the education and science level, and will accelerate the development of technologies and relevant industries. On the other hand, the technological development in all fields demands high energy batteries as power sources, energy backup and storage systems with high durability, stability and safety. Therefore, new high performance battery materials are urged by these demands, and play critical role in the technological developments in many fields from medical applications to high power energy storage, electric transport and portable electronics. Hence, the proposed project execution and successful accomplishment promise strong economic, social and ecological impact due to its importance, particularly for the renewable energy field and green transportation, which are one of the key attributes of sustainable development of our modern society.
Thus, the purpose of this innovative and outstanding research is preparation and electrochemical evaluation of novel 3D structured Si thin film anode material epitaxially grown on SiC buffer layer through the CVD technique, as well as synthesis and development of novel solid state electrolyte materials for high capacity, durable and safe Li-ion microbattery.
