Herein, 904L stainless steel has been successfully prepared using as the negative grid for lead-acid batteries. The morphologies and composites are investigated by field-emission scanning electron microscopy (FESEM), energy dispersive X-ray spectrometer (EDS) and powder X-ray diffraction (XRD). In addition, the electrochemical properties of the negative electrode are carried out in a three-electrode. Lead-acid batteries based on lead plate as the anode and lead-coated 904L as the cathode exhibits excellent specific capacity (179.5 mAh/g) and good cycling stability owing to high electrical conductivity and corrosion resistance of the 904L stainless steel. These results suggest that 904L stainless steel is a potential grid for lead-acid batteries.
Keywords:904L stainless steel; lead; negative grid; lead-acid batteries
