Hydrothermal LiTiO2 Cathode and Polyurethane Binder of High Current Lithium Ion Batteries

Vega Fresamitia Ingried, Sri Haryati, Nirwan Syarif


This research is to prepare a lithium-ion battery using carbon-based water spinach rods as anode and LiTiO2 as a cathode. Carbon and LiTiO2 are used as electrodes to produce lithium-ion batteries on a laboratory scale. Carbon derived from water spinach produces more economic value and is easy to obtain. The electrolytes used are liquid and gel-based LiCl with 10%, 20%, and 40% concentrations. The binder used to prepare lithium-ion batteries is a polyurethane (PU) binder. Lithium-ion batteries (LIBs) are arranged as anode-separator/electrolyte-cathode. The battery was tested with a potentiostat in cyclic voltammetry and galvanostatic modes. In cyclic voltammetry measurements, the value of the current in the lithium-ion battery and the plot on the cyclic voltammetric graph can be used to calculate the value of power and energy. Galvanostatic measurement aims to determine the time it takes to charge and discharge the lithium-ion battery. The measurement of cyclic voltammetry on the performance of lithium-ion batteries shows the highest current value found in batteries with a liquid electrolyte media concentration of 40% by 0.18A, while the lowest current value is found in batteries with a 10% concentration gel electrolyte media of 0.004A. The highest power and energy values are found in batteries with a liquid electrolyte media concentration of 20%. The lowest power and energy values are found in batteries with 10% concentration gel electrolyte media. In the galvanostatic measurement, a graph of charging and discharging lithium-ion batteries is produced. The fastest charging slope is in the battery, with a liquid electrolyte media concentration of 40%. The slope discharge of liquid electrolyte media with a concentration of 40% is the fastest compared to other types of batteries. Batteries with 10% concentration gel electrolyte media become the batteries with the longest charging slope and the longest discharge slope compared to other types of batteries.
