Coffee Grounds

The battery is a storage medium for electrical energy for electronic devices developed effectively and efficiently. Sodium ion battery provide large-scale energy storage systems attributed to the natural existence of the sodium element on earth. The relatively inexpensive production costs and abundant sodium resources in nature make sodium ion batteries attractive to research. Currently, sodium ion batteries electrochemical performance is still less than lithium-ion batteries. The electrochemical performance of a sodium ion battery depends on the type of electrode material used in the manufacture of the batteries.. The main problem is to find a suitable electrode material with a high specific capacity and is stable. It is a struggle to increase the performance of sodium ion batteries. This literature study studied how to prepare high-performance sodium battery anodes through salt doping. The doping method is chosen to increase conductivity and electron transfer. Besides, this method still takes into account the factors of production costs and safety. The abundant coffee waste biomass in Indonesia was chosen as a precursor to preparing a sodium ion battery hard carbon anode to overcome environmental problems and increase the economic value of coffee grounds waste. Utilization of coffee grounds waste as hard carbon is an innovative solution to the accumulation of biomass waste and supports environmentally friendly renewable energy sources in Indonesia.
