NOVELTY - Electrochemical method comprises coating a substrate material with a first metal layer and a subsequent metal layer of lead/lead alloy; and electrodepositing an organic metal on the layer obtained at the end of first step using an electrolyte to form a protective layer and to obtain the grid structure (100).    USE - For manufacture of corrosion resistant grid structure for use in lead acid batteries.    ADVANTAGE - Provides faradaic efficiency of the battery is 90%. The battery experiences 38% increase in capacity at low discharge rate of C/20 and 50% of capacity at high discharge rate of 3C in relation to its capacity at C/5 rate. The battery exhibits 25% increase in capacity at 50degreesC in relation to its capacity at 25degreesC and at temperatures below 25degreesC, decrease with 38% capacity in comparison to the capacity value observed at 25degreesC. The battery accepts 90% of charge within 1.5 hours of charge during high rate charging. The self-discharge of the battery is found to be 0.3%/Day. The capacity loss is minimal during 100 cycles (claimed). It reduces the weight of lead-acid batteries and increasing their specific energy. It provides batteries that store high energy, but weigh less.    DETAILED DESCRIPTION - INDEPENDENT CLAIMS are also included for:    (a) a corrosion resistant grid structure for use in a lead-acid battery comprising substrate material coated with a first metal layer, a second metal layer of lead/lead alloy layer deposited on the first metal layer, and an organic metal layer electrodeposited on the lead/lead alloy layer;and    (b) battery comprising a positive plate; and a negative plate containing a grid structure, the grid structure comprising a substrate; a first metal layer deposited on the substrate; a second metal layer comprising a lead/lead alloy layer deposited on the first metal layer; and an electrically conductive and corrosion-resistant organic metal layer deposited on the lead/lead alloy layer    DESCRIPTION OF DRAWING(S) - The figure shows grid/plate structure.
