Positive plates for the carbon lead-acid battery (CLAB) with porous carbon grids coated with lead havebeen prepared and tested. Lead coating thickness in the range between 20 and 140 micrometers hasbeen shown to positively influence the discharging profile and the cyclic lifetime of the plates. Thickercoating improves both the cyclic life and discharge performance. The increase of battery specificenergy by 50% is expected by employing the lightweight carbon grid with 60 m lead coating forpositive plates, and 20 m for negative.
