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.
