Local Indonesian biomass based hard carbons as low cost and promising electrodes for sodium ion batteries : laporan penelitian
Currently, one crucial issue in the development of rechargeable batteries is to find an alternative battery system to replace lithium-ion battery (LIB) in order to solve the issue of safety and scarcity of lithium. Sodium ion battery (SIB) can be taken as one of the most interesting options for it due to the abundance of sodium sources and low prices. In this battery system, hard carbons are usually utilized as anode materials due to their excellent electrochemical performances. However, such kinds of carbon materials are derived from fossil sources such as coals. Hence, the production process is not sustainable to the environment and it is also expensive. To solve these problems, the utilization of biomass wastes as hard carbon precursors of anode materials can be taken into account based on the cost and environmental aspects. Until now, there is only few research works focused on the development of biomass based materials for electrode's materials in 518.
In this context, the main aim of this proposed project is to produce hard carbons as anode materials for SIB from the local Indonesian biomass (starch) and mapping the correlation among biomass characteristics (cellulose, lignin, hemicellulose contents), process conditions and resulting carbon quality regarding the electrochemical application (surface area, porosity, crystallinity, degree of disorder carbons). This proposed project can be divided into four main stages. Firstly, the preparation of hard carbons will be conducted by simple hydrothermal and followed by the activation process. Secondly, the structural and physical characterizations of the carbon products will be investigated by several instruments such as Scanning Electron Microscope (SEM), X-Ray Diffraction (XRD), Transmission Electron Microscope (TEM) or Raman Spectroscopy. Thirdly, the electrochemical characterizations of hard carbon anodes for SIB will be conducted to assess battery performance. Finally, based on the experimental results, specific model correlating carbon quality versus biomass composition and operating conditions will be proposed.
The outcome of this project is mainly to publish in scientific journals. This project is proposed for three years. We have now the remaining two years. For the second and third year, the target journal for publication is the Journal of Materials Chemistry and Physics (Elsevier) or Applied Electrochemistry (Springer). 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 ion batteries by a simple process so it can be developed to the cost-effective mass production. The mass production of low
cost electrode materials will contribute to the development of renewable energy technology in the future.
