TECHNICAL DETAILS OF PAM EFFICIENCY
ACTIVATOR
The Lead Acid Battery having many applications, these include
high specific power and power density, high volumetric energy
density & specific energy (energy per unit weight)
The need for improved energy storage devices to handle the
increased load & capacity has followed the incremental usage of
electrical power devices in automobiles. Larger engines, higher
crank speed, and increasing customer expectation have
motivated the industry to provide higher specific energy and
longer service life.

PAM EFFICIENCY ACTIVATOR is incorporated in the
composite electrochemically active material carried on the lead
plates of a lead-acid storage battery. In the case of the positive
electrodes, the result is to lengthen the service life of more
than 20%.
PAM EFFICIENCY ACTIVATOR offers a battery plate that virtually
eliminates flaking and shedding of positive plate active materials
i.e. the main reason for battery failure. The PAM EFFICIENCY
ACTIVATOR forms fibers, and these fibers create a complex
matrix that traps and binds the active material together. The result
of shedding and flaking are virtually eliminated, the lead paste
remains cohesive, and contact with the positive grid remains in
place for a longer period.

During the charge and discharge cycle, a paste type positive
electrode plate repeatedly expands and shrinks and eventually
swells by producing fine particles so that the active material is
dropped out from the grid, thus resulting in shortening of the
cycle life.PAM EFFICIENCY ACTIVATOR forms a mesh-type
network involving active material particles, so as to avoid
dropping out.

PAM EFFICIENCY ACTIVATOR is made of a carbon
backbone chain, and each carbon has two fluorine
atoms attached to it.

PAM EFFICIENCY ACTIVATOR has shown that the ampere-hour
capacity of lead-acid batteries increases, i.e. the efficiency of the
electrically formed active material raises, with an increase in the
amount of sulfuric acid and/or water used in the preparation of the
paste. This increases the porosity and thus the surface area of the
positive electrode active mass.

How the Positive Active Material Works in a Lead Acid Batteries.
Pb(IV)O2 + SO42- + 4H+ + 2e- = Pb(II)SO4 + 2H2O Ion conductivity
-Sulfuric acid is a reactant
-Reaction limited by diffusion at fast discharge Electrical
conductivity
-PbO2 is a conductor, PbSO4 is not
-Reaction limited by paste conductivity at slow discharge
At fast discharge rates, the hydrogen sulfate is consumed faster than
it can diffuse into the plate, limiting the overall PAM EFFICIENCY
ACTIVATOR increase in utilization at a fast discharge rate. PAM
EFFICIENCY ACTIVATOR significantly protects grids from corrosion
& increases mechanical strength of the plate.

PAM efficiency Activator increases specific energy and porosity of
the plates. If the porosity of the positive active material is
increased, the diffusion of electrolyte into the plate is enhanced
and thus more of the active material will react, which again
increases the specific energy. The magnitude of both these effect
depends on both the discharge rate & the battery design.
The maximum increase in utilization is reached with addition of
PAM Efficiency Activator. The positive grid is subject to corrosion,
the rate of this debilitating process is influenced by grid
composition & microstructure, Plate potential, electrolyte
composition, temperature. The corrosion is generally more
electrically resistive than the grid & thus diminishes the output of
the battery in extreme cases, corrosion results in disintegration of
the grid & collapse of the plate.

PAM Efficiency Activator provides binding protective shell to
paste while charge and discharge mechanism, thus it provides
long lasting reinforcement to the paste on the battery plate. By
use of this positive plates have long cycle life and high
coefficient of utilization. High charge retention at long storage
time in wet condition.
Therefore, PAM EFFICIENCY ACTIVATOR provides all types of
electrode plates for the lead-acid battery having a wide range of
applications and great value in industry.
