Abstract

Bahan elektroda yang digunakan dalam baterai ion lithium berbentuk lembaran komposit yang dilapiskan pada pengumpul arus. Komposit elektroda terdiri dari bahan aktif/elektroda, aditif bersifat konduktif elektronik dan matriks berbasis polimer. Performa baterai antara lain diindikasikan oleh kapasitas spesifik (mAh/g), densitas kapasitas (mAh/cm2), kemampuan tingkat/ rate capability dan tahanan dalam. Pada penelitian ini dibuat komposit bahan aktif katoda LiFePO4, aditif Acetylene Black dan matriks PVdF dengan perbandingan komposisi berat 85:10:5. Grafit dan 1 M LiPF6 dalam larutan EC dan DEC digunakan masing-masing sebagai anoda dan cairan elektrolit. Verifikasi fasa dari bahan katoda dan anoda dilakukan melalui analisis pola difraksi XRD. Morfologi lembaran elektroda dianalisis melalui SEM. Analisis performa baterai dari komposit dengan variasi ketebalan slurry (50, 100 dan 300 μm) menggunakan battery analyzer. Hasil analisis menunjukan semakin tebal lembar komposit semakin besar kapasitas spesifik (mAh/g) dan densitas kapasitas (mAh/cm2) namun rate capability menurun disebabkan tahanan dalam lembar yang meningkat.

Abstract

The effect of sintering temperature on the characteristics of sodium lithium titanate (NaLiTi3O7/NaLTO) synthesized at different solid-state reaction temperature and its performance as lithium-ion battery anode has been investigated. The precursors for the synthesis consisted of LiOH.H2O, TiO2, and NaHCO3. The synthesis was performed via solid-state reaction method. The precursors were mixed and sintered at variation temperatures of 900oC, 1000oC, and 1100oC for 2 hours under atmosphere condition. The final product was characterized using X-ray diffraction (XRD) and particle size analyzer (PSA). The XRD analysis showed the main phase of NaLTO with some impurities. PSA analysis showed that the sintering temperature has a significant effect on changes in particle size where the sample at a temperature of 1100oC has the largest particle size of 74.62 µm. The battery was fabricated by firstly mixing NaLTO powder with polyvinylidene fluoride (PVDF) and acetylene black (AB) in a ratio of 85:10:5 wt.% and the mix was then deposited onto copper foil to form NaLTO a sheet. The NaLTO sheet was cut into circular discs with a diameter of 14 mm and were arranged in a sequence of separator, metallic lithium, and electrolyte to form a coin cell in a glove box. Characterization using cyclic voltammetry (CV) and charge-discharge (CD) showed that the NaLTO sintered at 1000oC provided good electrochemical performance with the largest diffusion coefficient of 3.948 x 10-10 m2/s, Coulombic efficiency reached 100%, and a high specific capacity of 65.83 mAh/g.

Abstract

In order to fulfill the demand for high energy and capacity, an electrode with high-voltage capability, namely LiNi0.5Mn1.5O4 (LNMO) that has an operating potential of up to 4.7 V vs Li/Li+, is currently becoming popular in Li-ion battery chemistries. This research produced LNMO by using a solid-state method with only one-step synthesis route to compare its electrochemical performance with different lithium sources, including hydroxide (LNMO-LiOH), acetate (LNMO-LiAce), and carbonate (LNMO-LiCar) precursors. TGA/DSC was first performed for all three sample precursors to ensure the optimal calcination temperature, while XRD and SEM characterized the physical properties. The electrochemical measurements, including cyclic voltammetry and charge-discharge, were conducted in the half-cell configurations of LNMO//Li-metal using a standard 1 M LiPF6 electrolyte. LNMO-LiOH samples exhibited the highest purity and the smallest particle size, with values of 93.3% and 418 nm, respectively. In contrast, samples with higher impurities, such as LNMO-LiCar, mainly in the form of LixNi1-xO (LiNiO), displayed the largest particle size. The highest working voltage possessed by LNMO-LiOH samples was 4.735 V vs Li/Li+. The results showed that LNMO samples with LiNiO impurities would affect the reaction behavior that occurs at the cathode-electrolyte interface during the release of lithium-ions, resulting in high resistance at the battery operations and decreasing the specific capacity of the LNMO during discharging. The highest value, shown by LNMO-LiOH, was up to 92.75 mAh/g. On the other side, LNMO-LiCar only possessed a specific capacity of 44.57 mAh/g, indicating a significant impact of different lithium sources in the overall performances of LNMO cathode.

Abstract

Synthesis of Lithium Manganese Oxide (LiMn2O4) for Lithium Ion Battery Cathodes with Solution Method has been conducted. This experiment was carried out using the solution method. In this study, the synthesis was carried out by varying the calcination temperature. The raw materials used were Lithium Acetate (C2H3O2Li), Manganese Acetate (C4H6MnO4.4H2O), Hydrochloric Acid (HCl), and Ethanol (C2H5OH) as solvents which were dissolved to become LiMn2O4 precursors. Synthesis was carried out at calcination temperatures of 600oC, 700oC and 800oC, for 4 hours then pounded with a mortar until smooth. The characterization includes: The results of the STA test at 280oC-380oC showed a mass decrease of 11.9973% due to the release of mass of water vapor and decomposition of C4H6MnO4.4H2O raw material. XRD analysis shows that the increase in peak temperature of the LiMn2O4 phase intensity is getting sharper, the peak showing the impurity Li2O phase decreases. SEM analysis results show that the higher the calcination temperature, the larger the particle size is formed, because in the calcination process the densification process occurs.

Abstract

Rechargeable batteries have been implemented in most portable electronic devices. Lithium-ion battery (LIB), as the main power source, dominates the mobile device market due to its high energy density, long shelf life, and environmentally friendly operation. In the rechargeable lithium-ion battery, there are four main components, one of which is the anode. The anode material used is commercial graphite. Thus, this study aims to determine the effect of solid content solvents on battery performance. The main discussion in this study is to analyze the effect of solvent variations of N, N Dimethyl Acetamide (DMAC) on the characteristics of the sheet and the difference in solid content of graphite anode sheets on battery performance. Identification of the formed phase was carried out by XRD, reduction and oxidation reactions by cyclic voltammetry test, battery capacity by charge/discharge test, and study of the electrochemical characteristics of the electrode material by electrochemical impedance spectroscopy test. The best anode sheet is produced by mixing 2.5 mL DMAC solvent at a thickness of 0.07 mm with a solid content of 25%. The results of the charge-discharge test showed a specific capacity of 309.33 mAh/g in the first cycle.

Abstract

This study investigates the synthesis via solid state reaction and characterization of Li₇La₃Zr₂O₁₂ (LLZO) as a solid electrolyte doped with Al₂O₃ using a one-step heat treatment (sintering at 900°C for 4 hours). Samples were prepared with doping variations; pure LLZO (0Al-LLZO), 0.25Al-LLZO, and 0.5Al-LLZO, based on the formula  with x = 0, 0.25, and 0.5, and were mixed using ball milling for 4 hours at 25 Hz. XRD and Rietveld refinement confirmed the formation of a dominant tetragonal Li₇La₃Zr₂O₁₂ phase alongside minor secondary phases. Grain sizes ranged from 1.2 to 1.3 µm, and densification improved with increasing Al content. The 0.25Al-LLZO sample exhibited the highest ionic conductivity of 2.83 × 10⁻⁹ S/cm at room temperature, representing a 2.96-fold increase over undoped LLZO. These results indicate that Al doping significantly enhances structural stability and Li-ion transport in LLZO electrolytes processed at moderate temperatures.
