Li-ion batteries are one of the most frequently used energy storage materials, as they are utilized in a variety of applications, including electronic portable devices and electric vehicles. As one of the world's major mineral reserves (i.e., Nickel, Bauxite, Cobalt, Copper, and Manganese), Indonesia possesses enormous potential for the development of high energy LIB. Our team concentrated on the creation of a cathode with a high voltage and a large capacity, recognizing the constraint and addressing it through material modification in order to enhance the electrochemical performance of the advanced LIB. In addition, our team is devoted to assisting Indonesia in becoming one of the world's leading battery producers through the development of human resources and a significant breakthrough in the creation of Li ion batteries.

The extensive use of Li-ion batteries in electronic portable devices and electric vehicles contributes to the rapid increase of Li-ion battery end-of-life waste. Specifically, wasted LIBs include hazardous yet valuable transition metals (e.g., Ni, Co, and Mn) as well as damaging HF as a side reaction product. Utilizing organic acids and organic reducing agents to recover important metals, our team concentrated on a green and environmentally friendly cathode recycling approach based on hydrometallurgical technique. These materials can be utilized to resynthesize the cathode that will be combined with the other battery components. The resynthesized cathode has outstanding electrochemical properties comparable to those of a cathode with the same chemical composition as the original cathode. This study demonstrates that rather of relying solely on mined minerals, recycled materials can be exploited as a new source for cathode manufacturing.

Recently, supercapacitors have evolved as energy storage devices that meet the requirement for high-power storage devices. To develop a high-performance supercapacitor, substantial research has focused on expanding the material's surface area. Due to its high surface-to-volume ratio, quantum dots have attracted significant attention in the past year. Our team has created a variety of TMS Quantum Dots for use in supercapacitor applications, with superior or equivalent performance to other cutting-edge materials. Our supercapacitor is also stable up to a thousand cycles, indicating a bright future for this material in devices for sustainable energy storage.

Graphene is a carbon-based substance that has captured the interest of scientists worldwide. Due to its extraordinary qualities, which include strong electrical conductivity, a wide surface area, excellent mechanical strength, and superb flexibility, it is a remarkable material. Electrodes in energy storage devices are one of the most intriguing applications of graphene. Our study focuses on developing a simple and environmentally friendly method to manufacture graphene or graphene-derivative materials with exceptional electrical characteristics to enable the effective passage of charge in the electrode. The produced graphene is then used as the supercapacitor's active material or as an addition to enhance the performance of metal-based supercapacitor electrodes.
