Copper-Coated Graphite Felt as Current Collector for Li-Ion Batteries

Lithium-ion batteries (LIBs) undoubtedly are considered a viable option to meet the ever-increasing demands for portable consumer electronic devices and electric vehicles. To this requirement, intensive research is being conducted on increasing volumetric gravimetric energy density of LIBs as well developing high-capacity electrode materials LIB. In study, novel copper-coated graphite felt current collector proposed use constituent Different type Cu-coated electrodes were synthesized. They characterized by X-ray Diffractometer (XRD). test its electrochemical performance Electrochemical Impedance Spectroscopy (EIS) cyclic voltammetry (CVA) techniques used. Materials with specific capacity up 473 mAh?g?1 obtained. It was found that nature gain carbon differs from due different crystal structure. The copper coating reduces charge transfer resistance increases material. Therefore, such new anode may be successfully used in LIBs.
