Lithium metal oxide such as NMC and NCA have been widely commercialized as electric vehicles. However, the cobalt content in the material is harmful to the environment, toxic, and expensive. This research aims to create a cathode material with a lower cost, efficient, and eco-friendly by extracting aluminum from the beverage cans waste as a cation-doping on the substitution of nickel material elements to repair material stability and electrochemistry performance. This study synthesized LNO cathode material by a solid-state method because it is low production cost and easy to synthesize. The extraction of beverage can waste successfully synthesized into alumina compounds corresponding to JCPDS card No. 29-0063. LNO cathode materials were prepared with a stoichiometric composition variation of LNO-P, LNO-Al 0.03, LNO-Al 0.07, and LNO-Al 0.1. Materials that have been successfully synthesized will be tested by X-Ray Diffraction to indicate that the material has a layered-hexagonal structure with high degree ordering. Fourier Transformed Infrared Spectroscopy tests to determine the composition of functional groups on LNO materials. The Scanning Electron Microscope analyzes the shape and morphology of surface material particles. Electrochemical testing uses cylinder batteries with a current of 0.1 C (1 C = 200 mA g-1) and a voltage of 2.6-4.3 volts, where obtained batteries LNO-P, LNO-Al 0.03, LNO-Al 0.07, and LNO-Al 0.1 with discharge capacity of 4.22 mAh g-1, 31.82 mAh g-1, 36.67 mAh g-1, and 37.48 mAh g-1

Lithium iron phosphate (LiFePO4) batteries have received much attention because they can provide higher power density with abundant raw materials, better safety, low toxicity, and high thermal stability. In general, the production of LiFePO4 cathodes uses polyvinylidene fluoride (PVDF) as a binder and N-methyl-2-pyrrolidone (NMP) as a solvent. These components are expensive, toxic, and can adversely affect the environment. Therefore, to address these shortcomings, the solvent and binder were replaced in this study. The solvent in the current study is water. The water soluble binders employed in this study are carboxymethyl cellulose (CMC) and styrene-butadiene rubber (SBR). Suitable electrode formulations were investigated to obtain high performance cylindrical Li-ion batteries. As a result, a formulation with a ratio of LiFePO4:AB:KS6:SBR:CMC equal to 90:3:3:2.677:1.333 was used. It has a high specific discharge capacity, 120 mAh/g. This NMP-based cathode can yield about 145 mAh/g, which is slightly higher than a water-based LiFePO4 cathode.
