Zinc air-alkaline batteries

The process is based on the oxidation of zinc at the anode and the reduction of oxygen at the cathode. This electrochemical reaction delivers a stable power supply over an extended period.

Applications: zinc air-alkaline batteries

The zinc-air alkaline technology was developed by Cegasa. The batteries are being used in various applications, including:

• railway signal lighting
• disposable signal lighting
• buoy and marine signal lighting
• telecommunication installations
• parking meters
• electric fence

Zinc air batteries by Cegasa

Elfa offers zinc-air alkaline batteries from Cegasa, including models such as the E/Z8 6/50.

This battery is well suited for applications with low power consumption and constant energy demands, where long-term operation without intervention or maintenance is required.

Benefits of Cesaga's battery chemistry

The battery chemistry developed by Cegasa offers several advantages that may benefit your application.

• High energy density: lots of energy in a small format; ideal for limited space/weight.
• Low self-discharge: long shelf life and suitable for long-term use without replacement.
• High output voltage: provides sufficient power immediately, often without additional voltage converters.
• Constant voltage (< 2% variation): stable, reliable performance down to almost empty.
• Wide temperature range (-20ºC to +50ºC): works reliably in cold and hot environments.
• Moisture resistant (25— 85% RH): continues to perform when humidity changes.
• More durable: no heavy metals such as lead or cadmium; more environmentally friendly alternative.

Disadvantages of zinc-air alkaline identified

Every battery chemistry has its limitations. That’s why we believe it’s important to highlight not only the advantages, but also the disadvantages. This ensures a well-informed assessment of whether a particular chemistry is suitable for your application.

• Non-rechargeable: in contrast to battery types such as lithium-ion batteries, zinc air-alkaline batteries are designed for single use. This can lead to higher replacement costs and more waste.
• Sensitive to extreme conditions: very high humidity or dryness may affect performance and longevity.
• Oxygen required: works on air supply; it performs less in enclosed or poorly ventilated areas.
• Less suitable for peak loads: provides relatively lower peak flows, so less ideal for devices with short, high power demand.
