“…The cobalt oxide powder can be readily converted to LiCoO2 material through solid-state high temperature sintering (equation 3) reservoir in the anode. However, the value of 121 mAh/g is considered high enough to be developed for large scale production of LiCoO2 [15,16]. Figure 4b shows the cycle performance of LiCoO2 at elevated current rate of 2C.…”

LiCoO2 cathode material has been continuously applied in commercial LIBs cells. It has high gravimetric and volumetric density. In this research, an economical approach to obtain LiCoO2 is proposed. Pure cobalt oxide (Co3O4) precursor was obtained via atmospheric precipitation of cobalt sulfate and thermal decomposition of the as-obtained hydroxide precursor. The next heat treatment was performed to obtain LiCoO2 powder. To investigate the characteristic of the precursor and the final product, XRD, FTIR, and SEM analysis were conducted. The final product has hexagonal structure and quasi spherical morphology. The size of the particle is in micron. The charge-discharge analysis of LiCoO2 was conducted in LiCoO2/Graphite system where the initial capacity of LiCoO2 is 120 mAh/g at the current density of 0.1 C (20 mA/g). Overall, this method can be used for large scale LiCoO2 cell production.

Electricity is the most energy demanded in this era. Energy storage devices must be able to store long-term and portable. A lithium ion battery is a type of battery that has been occupied in a secondary battery market. Lithium iron phosphate / LiFePO4 is a type of cathode material in ion lithium batteries that is very well known for its environmental friendliness and low prices. LiFePO4/C powder can be obtained from the solid state method. In this study the variables used were the types of precursors : iron sulfate (FeSO4), iron oxalate (FeC2O4) and FeSO4+charcoal. Synthesis of LiFePO4/C powder using Li:Fe:P at 1:1:1 %mol. Based on the XRD results, LiFePO4/C from FeSO4+charcoal shows the LiFePO4/C peaks according to the JCPDS Card with slight impurities when compared to other precursors. XRD results of LiFePO4/C with precursors of FeSO4 or FeC2O4 shows more impurities peaks. This LiFePO4/C cathode is paired with lithium metal anode, activated by a separator, LiPF6 as electrolyte. Then this arrangement is assembled become a coin cell battery. Based on the electrochemical results, Initial discharge capacity of LiFePO4/C from the FeSO4 precursor is 19.72 mAh/g, while LiFePO4/C with the FeC2O4 precursor can obtain initial discharge capacity of 17.99 mAh/g, and LiFePO4/C with FeSO4+charcoal exhibit initial discharge capacity of 21.36 mAh/g. This means that the presence of charcoal helps glucose and nitrogen gas as reducing agents.

“…This test was measured by galvanostatic charge-discharge using 18650-cylinder cells. The charging process was by the transfer of Li ions in the cathode material to the anode through the electrolyte and vice versa [40]. The results of the charge-discharge test at a current 0.1 C is presented in Fig.…”

The synthesis of Ni0.8Co0.15Al0.05O2 (NCA) cathode material is performed using the one-pot synthesis. This system is combined with the solution combustion method to produce ternary metal oxide (TMO). Nitric acid acts as an oxidizer and various amount of urea act as fuel for the combustion process. NCA material has a good hexagonal layer structure and the average particle size obtained was 1.17 µm. The electrochemical analysis showed that NCA cathode material obtained at a ratio NCA-OH: urea = 1: 2 has the highest specific discharge capacities of 118.617 mAh.g-1, with a stability of up to 10 cycles.
