Preparation of biomass based material as electrode's component for sodium sulfur battery operated at room and intermediate temperature

The development of low-cost energy storage technology is very urgent to follow the growing progress of renewable energy resources to provide the electricity. Compared to the lithium ion battery system, sodium-sulfur (NaS) batteries offer low-cost technology for energy storage applications because of the high capacities of sodium and sulfur as well as their abundant resources. NaS batteries operated at high temperature (300-350 °C) have been commercially applied for large scale energy storage and conversion. However, the safety concerns and high operation cost are the main constraints to prevent them for widespread applications. Hence, to operate this battery technology on the room temperature and intermediate range can lead to lower material costs, mitigate thermal management and safety issues and enhance cycle life.

In this battery system, carbon-sulfur composites are usually used as cathode materials to improve their electrochemical performances. Until now, carbon materials are commonly come from the unrenewable resources such as coals. So, the material synthesis is not sustainable to the environment and it is also expensive. For alternative, the utilization of biomass as carbon precursors of cathode materials for NaS battery can be explored to minimize the cost. Until now, only few research works are conducted for the development of biomass-based materials for electrode's materials in NaS battery.

In this context, the main aim of this project is to prepare carbon-sulfur composites as cathode materials for NaS battery derived from the biomass (microalgae). This proposed project consists of three main stages. The first stage is the preparation and characterizations of carbon materials and their composites. The second stage is the electrochemical studies of carbon-sulfur cathodes for NaS battery operated at room temperature (25-60°C) by varying the type of the electrolyte for optimized operation. The third one is related to the electrochemical studies of NaS battery at intermediate temperature range (100-200 °C).

The outcome of this project is mainly to publish in scientific journals. This project is proposed for three years. For the first year, the target journal for publication is the Journal of Electrochemical Society. As expected, the final target technological readiness level (TRL) of this project is about 2 or 3. The long-term goal of this project is to prepare low-cost electrode materials for sodium sulfur battery so it can be operated efficiently in the room and intermediate temperature range. By operating the sodium sulfur battery at lower temperature, it will reduce the operational costs as well as to guarantee the safety reasons.
