Expander ( CHEMPFIX™)

CHEMPFIX™EXPANDER, a premium product designed differently for Automotive and Industrial applications. It is well known for improving battery performance through:

  • Extended cycle life
  • Superior cold cranking capabilities
  • Increased Reserve capacity

How CHEMPFIX™ EXPANDER works.

Organic expanders are essential performance enhancing additives that are unlike bulk commodities such as sulphuric acid, lead or lead oxide. They are well known for their ability to improve the utilisation of the negative active material (NAM) and to preserve and maintain the performance of NAM over the service life of the battery.

CHEMPFIX™ EXPANDER have an influence on the deposition of lead sulphate on discharge. It affects the growth of lead sulphate and increases the electrical conductivity of the mixture. If a battery undergoes shallow charge discharge cycles there was practically no deterioration of the lead on negative plate. But if a cell was kept in deep discharged state, remarkable deterioration of the negative plate was found.

CHEMPFIX™ EXPANDER is known to prevent the deterioration of the negative plate as it keeps the lead porous, fine grained and suppresses the evolution of hydrogen and enables a negative plate to be charged easily. It improves the cycle life and ampere capacity of the negative plate.

Use of CHEMPFIX™ EXPANDER will keep on reducing the oxidation of sponge lead during drying, thus preserving the lead as sponge lead. Addition of CHEMPFIX™ EXPANDER to negative plate results in high rate discharge capability in winter climate. In hot weather or high climate, like India, it gives the plate overcharge capability due to high temperature charging. It does not allow the negative plate to shrink due to overcharge on float current charging.

Hence by using CHEMPFIX™ EXPANDER cycle life, capacity and utilization of active material is increased with better performance all the year round.

Batteries are engineered with optimised ratios of positive active material, negative active material and electrolyte. To meet standards of reserve capacity, cold crank ability, and especially battery life, engineers need to get maximum efficiency out of the negative active material, otherwise the under-utilised mass is simply unproductive weight and expense. It is well established that the investment in CHEMPFIX™ EXPANDER as an organic expander returns in performance its cost many times over. Simply put, lead-acid batteries do not function optimally without the use of CHEMPFIX EXPANDER.

Energizer (CHEMPFIX™)

Very few lead acid batteries are replaced because they stop working. In almost every case the battery is replaced because it doesn't work well enough anymore. What is not generally realized is that something can be done at this stage which may prolong the useful life of the battery - quite often by many years, and that the treatment carried out earlier in the battery's life may well have stopped the symptoms from occurring in the first place.

The reason for a battery failing is due to the chemical processes which take place in each cell when the battery is not fully charged. Even the slightest discharge condition allows both plates to react slowly with the sulphuric acid electrolyte to form lead ions. It is these lead ions which cause problems; they combine with sulphate ions in sulphuric acid to form highly insoluble lead sulphate. When this coats the plates of the battery, it fails to deliver enough power to be of use. The battery may well be serviceable every other way – only the "sulphating" stops the battery from delivering enough power to be of use.

The sulphating can effectively be removed, or prevented, by adding CHEMPFIX ENERGIZER to each cell. This chemical forms co-ordination compounds with lead ions formed in the discharge cycle of a battery. The compound formed by lead ions and the CHEMPFIX ENERGIZER ion is not particularly stable in the acid medium of a battery, but when it breaks down again any lead sulphate regenerated tends to drop to the bottom of the cell where it lays harmlessly since it doesn't conduct electricity. Any regenerated CHEMPFIX ENERGIZER ions are free to continue their work.

CHEMPFIX ENERGIZER is used to dissolve sulphate deposits from lead acid batteries. The net effect is to lower the cost of battery based electricity by recovering otherwise unusable batteries. You can prolong the life of batteries by using CHEMPFIX ENERGIZER that prevents sulphation. Supposed to be particularly good for batteries subjected to infrequent use, short trips, or inefficient charging system.

Mix the required amount of CHEMPFIX ENERGIZER to the battery cells so that the cells get the required amount. The amount to use depends on the size of the battery and on how much sulphate it has.

Charging or equalizing the battery after adding the CHEMPFIX ENERGIZER will help circulate the chemical and start the cleaning process.

ST (Additive for negative paste)

CHEMPFIX™- ST is used as a negative plate additive in the manufacture of lead-acid batteries. It is added at the rate of 0.2%of the oxide while preparing the paste. It is believed to enhance the hydrophobicity of the negative plate, particularly during dry-charging process. It reduces the extension of oxidation of the freshly formed lead (negative active material) when the plates are kept for drying in the open atmosphere after the process of tank formation. As a consequence, the charging time of a dry uncharged battery during initial filling and charging (IFC) is comparatively lower, as compared to a battery assembled with plates which do not contain CHEMPFIX™-ST additive.

Geltech (CHEMPFIX™)

One of the major failure mechanisms with VRLA cells used primarily is premature loss of the electrolyte within the cell, or accelerated water loss. This often results in a dry out condition within the cell which can lead to thermal runaway in extreme events if not detected prior to the event.

A major advantage for the “Gel” is the extra water in the battery. As long as recombination is good, the extra water simply translates to extra life. Dry out can be a major failure mode in VRLA batteries and can be countered by good recombination efficiency and adding water to the battery. Unfortunately, just adding water to the battery will lower the efficiency of recombination so that it approaches that of flooded batteries. The gel facilitates recombination, since it crack sand provides pathways for the oxygen to reach the negatives.

Measuring the polarizations in VRLA batteries is difficult, but it was found that the values in Gel showed a very small decrease in positive polarization (3 mV) that would point to a decreased corrosion rate and, thus, if the polarization difference remains, then the growth rate would also slightly favour increased life. 

The gel components does not participate in the electrochemical reactions and can be viewed as a dilutant for the sulphuric acid. The lower the concentration of gel, the higher is the battery capacity.

The heat capacity of a VRLA battery resides mostly in the electrolyte, and this provides an opportunity to increase the overall heat capacity by using gel. The electrolyte has over 65 % of the heat capacity and that can be increased, since the gel can be added in differing quantities. This extra heat capacity can help the battery survive fluctuating outdoor temperatures, since the excursions will be minimized and the battery temperature moderated.

The gelling time depends on the particle size and concentration of the colloid along with the concentration of the acid present and their resulting temperature. The gelling times can range from seconds to many tens of hours. Temperature has a rate effect .there is also an appreciable heat of mixing with the sulphuric acid. Cooling the sulphuric acid can slow the gelling, but, generally, the colloid cannot be frozen and this limits the increased time achievable.

The goal of permeating the active materials with gel can be achieved by choosing combinations that gel very slowly. Thus, diffusion has time to work, and the increase of acid concentration at the end of formation actually finishes the gelling. This provides a uniform gel that, since it permeates the battery, provides protection against acid stratification.

Since the gel permeates the active material and separator of the battery, its structure will decrease the acid stratification. The gel behaves like a very fine fibre glass separator and thus, the battery can cycle more effectively.
