Battery technology applications for energy storage are currently increasing. The most popular kind of battery in use today is the lithium-ion battery. However, lithium is limited. In fact, the need for batteries as energy storage devices grows over time. One alternative for replacing lithium-ion batteries is the sodium-ion battery because its characteristics are similar to lithium’s and it is very abundant. In this study, Na-NCM 532 has been successfully produced using a co-precipitation and solid-state method combination. The co-precipitation process, using oxalic acid as a precipitation agent and ammonia as a pH adjustor, can be used to create sodium ion-based cathode materials. It is clear from the characterization that the material has been formed and has a good structure. A hexagonally layered material structure can be seen in the XRD patterns. FTIR analysis revealed that the material was produced after the sintering process. The morphology of the substance, which has dimensions between 1 to 5 micrometers, was revealed by a SEM investigation. The EIS test results show a battery conductivity of 1.24 x 10-4 Scm-1. The electrochemical performance of the Na-NCM 532 cathode sodium battery and hard carbon anode was evaluated in a type 18650 cylindrical cell. The sodium battery was tested at a voltage window of 1.5-3.7 V and a current of 0.05C produced a capacity of 40 mAhg-1.

The lithium-ion battery is the most advanced battery technology widely available. Lithium rechargeable batteries have recently been used in transportation (for example, electric cars) and energy storage systems that need a lot of energy and power on a large scale. LiNi0.6Mn0.2Co0.2O2 (NMC622) is a cathode material that has a high energy density. Doping in lithium-ion battery cathode materials has become a topic of interest worldwide. In this study, NMC622 cathode synthesis was conducted with transition metal doping using co-precipitation. The co-precipitation approach was chosen for the material's production (LiNi0.6Mn0.2Co0.2O2)1-xMx (M = Fe, Ti, Zn, Ce, and Cu) because of its ability to produce particles with a high degree of atomic uniformity. Due to the high energy metal oxygen bond dissociation, Fe, Ti, Zn, Ce, and Cu were utilized as doping materials in this work. Oxalic acid was used as a precipitation agent, and ammonia was used as a chelating agent. The doping metal used was precipitated using oxalic acid. NMC622 which has been precipitated into NMC622 precursor and doped metal that has been precipitated is mixed for later solid-state processing. Under the flow of air, the obtained oxalate precursor is heated. The characterization of metal-doped NMC622 was carried out. The x-ray diffraction pattern depicts the hexagonal layered material's structure. FTIR analysis confirmed the missing C-O bonds of the obtained product. SEM (scanning electron microscope) studies show a polyhedral morphology of the material. A charge-discharge test at 1/10 C between 2.6 and 4.3 V was used to achieve the electrochemical performance. Ce doping resulted in the best specific capacity and could be compared with non-doped materials.

“…Ammonia and oxalic acid used in this process act as chelating and precipitant agents [41]. This co-precipitation reaction is obtained in the following equation [85]: xNi 2+ (aq) + yMn 2+ (aq) + zCo 2+ (aq) + NH4OH(aq) ⇌ NixMnyCoz(NH3) 2+ (aq) + H2O(l).…”

“…This is followed by the presintering process by putting the mixture into the furnace for 6 hours at 600ºC, followed by the sintering process for 12 hours at 800ºC with the inflow of oxygen. After leaving the furnace, the mixture was crushed and filtered using a 200 mesh sieve [85,86].…”

Li-ion batteries are one of the most popular energy storage devices widely applied to various kinds of equipment, such as mobile phones, medical and military equipment, etc. Therefore, due to its numerous advantages, especially on the NMC type, there is a predictable yearly increase in Li-ion batteries' demand. However, even though it is rechargeable, Li-ion batteries also have a usage time limit, thereby increasing the amount of waste disposed of in the environment. Therefore, this study aims to determine the optimum conditions and the potential and challenges from the waste Li-ion battery recycling process, which consists of pretreatment, metal extraction, and product preparation. Data were obtained by studying the literature related to Li-ion battery waste's recycling process, which was then compiled into a review. The results showed that the most optimum recycling process of Li-ion batteries consists of metal extraction by a leaching process that utilizes H2SO4 and H2O2 as leaching and reducing agents, respectively. Furthermore, it was proceeding with the manufacturing of a new Li-ion battery.
