Beside this, polymer usually used achieve expectable properties including each component. In this study, cellulose/poly(vinylidene fluoride) (PVDF) at different weight ratios. To investigate phase binary system, thermodynamic Flory-Huggings evaluated. The X-ray diffraction spectroscopy (XRD) analysis conducted structural samples. Differential scanning calorimetry (DSC) thermogravimetric (TGA) analyses were performed study thermal behaviors. Mechanical investigated tensile test such impedance (EIS), linear sweep voltammetry (LSV), chronoamperometry studied. results morphology these showed two polymers. This volume, which transfer; therefore, conductivity obtained range 10-4 S cm-1. addition, high transfer number (0.41 < t+ 0.97), wide (> 5 V), acceptable charge capacity 200 mAh/g 0.2C), achieved.

Energy demand has become a persistent concern and high‐performance energy storage systems have increasingly undergone development. Supercapacitors batteries pose great impact on garner deal of attention from technologies researchers alike. The performance saving devices is primarily determined by the electrode material in terms high specific capacitance, excellent conductivity, remarkable natural abundance, unique electrochemical qualities, also large surface area. Cobalt (Co)‐based materials are widely used devices. Nevertheless, combination Co ferrite such as nickel, zinc, copper, or Co/nonferrite like metal–organic frameworks layered double hydroxides improved their ultimate efficiency. This review deals with applications Co‐based materials, categorizing ferrites, characterization, performance, design manufacturing intended to supercapacitors applications.
