The absence of liquid electrolyte allows the power supply to operate even if the case is completely damaged

With the participation of RT-Project Technologies, a Rostec State Corporation holding company, import-substituting power supplies have been developed that are resistant not only to Arctic frosts and strong vibrations, but also to bullets. Unlike conventional electrolytic batteries, the new products can be mounted in any position. This solution could be used to start the engines of heavy military vehicles, as well as in uninterruptible power supply systems for command posts and communications centers.

The new batteries have a special design: they contain no liquid electrolyte; it is absorbed by special fiberglass "sponges." Therefore, even if the casing is damaged, the electrolyte does not leak, and the power supply continues to operate. This also allows the batteries to be mounted in any position, ensuring uninterrupted operation even during severe vibrations typical of tracked platforms moving over rough terrain. Power supplies using this technology have not previously been produced for military purposes in Russia.

"Issues of energy security and troop autonomy are today directly related to the quality of secondary power sources." "Combat and special-purpose vehicles must be able to operate in Arctic temperatures and maintain their capacity when the armored capsule overheats. The product line, developed in collaboration with NPP Impulse, has proven its effectiveness in extensive testing in extreme temperatures ranging from minus 50 to plus 50 degrees Celsius, with any battery orientation during installation, and under the most severe vibrations, as well as during hull penetrations. The service life of these products is measured in decades, and our production capacity allows us to produce 2 million such batteries annually, without relying on foreign components," noted Alexander Nazarov, Deputy Director General of Rostec State Corporation.
