Silver Oxide Zinc batteries

In this chemistry, the Silver Oxide is the Cathode and the Zinc is the Anode. Potassium Hydroxide liquid is used as electrolyte.

Being a high energy density battery intended for high rate applications in the field of Aerospace and Underwater.

There are two distinct type of batteries manufactured by High Energy Batteries using this chemistry viz.

Rechargeable Secondary Silver Oxide Zinc Batteries and Primary Reserve type Batteries.

Silver Zinc Batteries are mainly deployed in Fighter Aircraft’s, Launch Vehicles, Missiles and Torpedoes.

Silver Chloride Magnesium Sea Water Activated Batteries

In this chemistry, the Silver Chloride electrodes are used as Cathode and Magnesium Alloy electrodes are used as Anodes. Sea Water is used as the electrolyte.

HEB deploys this chemistry mainly for underwater propulsion and Sonobuoy applications. The batteries are deployed both in War shot and Exercise torpedoes for propulsion purposes.

Cuprous Chloride Magnesium Sea Water Activated Batteries

In this chemistry, the Cuprous Chloride electrodes are used as Cathode and Magnesium Alloy electrodes are used as Anodes. Sea Water is used as the electrolyte.

HEB deploys this chemistry mainly for Heavy Weight Torpedo Propulsion applications.

Nickel Cadmium Batteries

In this chemistry, Nickel Hydroxide electrodes are used as Cathode and Cadmium Hydroxide electrodes are used as Anode. Electrolyte is diluted solution of Potassium Hydroxide.

HEB deploys the above chemistry in two different forms viz., a) Sintered Plates (b) Fiber Nickel Cadmium for Aircraft applications, for Medium rate applications such as standby power source and for Industrial applications including Thermal Power Stations.

Lead Acid Batteries

(a). Flooded Type:
In this chemistry, Lead calcium alloy is used for both Positive and negative electrodes.

Lead peroxide electrodes are used as anodes and spongy lead electrodes are used as cathodes. Dilute sulfuric acid is used as electrolyte – keeping the electrodes immersed in the electrolyte.

These batteries are widely used for automotive application (Cars, LCV & HCV) and selectively in UPS / Inverter applications.

(b). VRLA Type (Valve Regulated Lead Acid Battery):
In this chemistry, the electrodes are similar to that of flooded version explained above. However, these batteries operate with Starved Electrolyte (Sulfuric acid) – where the electrolyte is absorbed in a special type of separator known as Absorptive Glass Mat Separator (AGM separator) – without any free electrolyte as in flooded system.

This lead acid battery works on “Oxygen recombination Cycle” principle with very low (or) no water loss in service life. Hence known as “Maintenance Free Batteries”. These are used in UPS / Inverter applications.
