Abstract

Lithium lanthanum titanate, Li0.2La0.6TiO3 (LLTO) was synthesized for the manufacture of lithium-ion capacitors using the solid-state reaction method. in this study, the active ingredients were synthesized using variations of lithium and lanthanum as raw materials. The raw materials used are Li2CO3, La2O3, and TiO2. The three raw materials were mixed according to the stoichiometric calculations then added 13 ml of Ethanol solution so that the raw materials were mixed evenly during the milling process for 5 hours. Sintering was carried out for 8 hours at 800oC and then at 1150oC for 12 hours. The sintered powder was ground using a mortar and pastel and then sieved on a 400 mesh sieve. The anode sheet was made by mixing the active ingredients: PVDF: Super-P with a composition of 85:10:5 by adding 3 ml of DMAC solvents. The characterization test was carried out using XRD while the electrochemical test used CV and EIS. The XRD result shows the formation of the main phase and the impurity phase with the main phase percent of 96.4%. From the results of electrochemical testing, the percentage of capacity is 73%.

Abstract

The lithium-ion battery has gained popularity among other secondary batteries for portable electronic devices and electric vehicle applications, especially the LiNi1/3Co1/3Mn1/3O2 or NMC111, considering its well-balanced configuration resulting in stable and safe electrochemical performance. NMC111 has been successfully prepared using a coprecipitation process at calcination temperatures from 800 to 950°C. The physical characteristics were investigated using X-Ray Diffraction (XRD), Scanning Electron Microscopy-Energy Dispersive Spectroscopy (SEM-EDS), and Particle Size Analysis (PSA). The XRD patterns showed the rhombohedral single phase for all calcination temperatures. Meanwhile, higher calcination temperatures offer higher degree of crystallinity, lower intensity ratio and more undesirable cation mixing. The particles with a uniform rectangle or pyramid shape are observed at the calcination temperature range from 800 to 900°C. However, bigger submicron particles with a rectangle or pyramid shape are detected at a higher temperature (950°C). The SEM-EDS mapping shows the homogeneity composition for all variation calcination temperatures. PSA analysis showed that calcination temperature at 800 and 850°C gives the particle less than 400 nm suggesting a potential material for a cathode of lithium-ion batteries.
