Electrochemical performance evaluation of galvanostatically deposited Co(OH)2 on few-layered graphene electrodes
In this paper, an electrochemical performance evaluation of galvanostatically deposited Co(OH)(2) onto few-layered graphene (FLG) is presented. The electrochemical evaluation was carried out in a twoelectrode symmetric cell arrangement. Electrodes were synthesized by combining FLG made through simple instrumentation atmospheric pressure-chemical vapor deposition (AP-CVD) process onto Cu foil substrates, and galvanostatically deposited Co by chronopotentiometry deposition. Faradaic contributions of as-deposited Co(OH)(2) increase the areal capacity of the electrochemical cells (EC) with an areal capacity of 0.72 mu A h cm(-2), in comparison with the FLG EC with an areal capacity of 0.04 mu A h cm(-2) at 4 mA cm(-2). Along with the areal capacity enhancement, specific energy, as the galvanostatic charge/discharge evaluation tells, showed a boost from 0.434 to 7.79 mW h g(-1) evaluated at 4 mA …
