In 1943 French professor Anry Andre has obtained the first recovery of accumulators, which had the soluble zinc electrodes and was quite incomplete. Continuing to improve a primary form of construction, in 1952 Andre proposed the method of making of silver-zinc accumulator with insoluble zinc electrodes.

One of the first space batteries was the Silver-Zinc battery, which dominated the industry in the 60's. This is a premium system with very high specific power and energy, but is quite expensive due to the use of silver. They are still used in selected applications, such as launch vehicles (rockets) and torpedoes. Mars Pathfinder also used a Silver-Zinc battery, but it was designed to be rechargeable. They have a relatively short cycle life, and are not used for multi-year missions. This type of battery is used commonly in the commercial market as hearing aid batteries.

ADVANTAGES:

High mechanical strength Capability of short-time discharge duty with heavy current Short self-discharge current, what gives the capability of long-term storage of accumulators in charged state High energy density, which exceeds energy density of lead accumulators about in three - four times The most environmentally friendly in the middle of industrial accumulators

LIMITATIONS:

High value Short number of overcharge cycles (50-100) Long charging time

Are used for military industry: aviation, satellite systems, divers and so on.
