The performance of Pb/C battery are evaluated and the stability of graphite sheet for negative electrode are confirmed . The crystallinity and surface morphology of graphite sheet are confirmed by XRD and SEM analysis before and after the operation of Pb/C battery. Pb / C battery with graphite sheet for negative electrode can be successfully operated at constant discharge voltage. This is because amorphous activated carbon layer on the surface of graphite sheet enhance adsoption/desorption reactions of hydrogen. This can also lead the superiority of charge acceptance compared with conventional Pb/C battery. As a result, it can be conclued that graphite sheets can be applied to Pb / C battery for the higher power and better charge acceptance. |
