Abstract
A precursor chemical compound is applied to a surface sought to be coated, and subjected to a rapid thermally activated chemical reaction process (RTACRP) in which the temperature is quickly raised and lowered. The desired coating is formed from the precursor chemical compound by a chemical reaction at the elevated temperature. The structural/chemical integrity of the surface is preserved due to the use of RTACRP. The approach may be used to manufacture a high-energy density lead-acid battery.
