For over 100 years, zinc has been known to be a good source of energy.  Zinc batteries have been used for many decades.  Zinc-carbon batteries are the longest established primary battery type and are comDigital hearing aidmon in applications such as remote controls, flashlights, toys and electronics.   Zinc-chloride batteries are an improved version of the zinc-carbon cells; they have a longer life and a steadier voltage output.

Button cell batteries are well known.  A significant number of them are non-rechargeable zinc-air batteries, which are commonly used in hearing aids, calculators and watches.  Research is being conducted in developing rechargeable zinc-air batteries.  Recently, zinc-air has shown potential as a fuel cell providing power to electric vehicles including scooters, buses and trucks.

batt_hxbugDue to the improved shelf life and leak resistance, the demand for zinc alkaline batteries has grown significantly. Zinc-alkaline batteries are widely used in light drain and heavy drain applications including radios, flashlights, cameras and toys.

Nickel-zinc batteries, which are rechargeable, can be utilized in power tools and automotive applications.

Silver-zinc batteries are used in applications requiring high reliability and an excellent energy/weight ratio. They are used in aircraft and space applications and selected portable electronic equipment.

Advantages of Zinc Energy

Excellent cbatt_rechargeableombination of physical and electrochemical properties. Zinc is a good reducing agent with a high theoretical capacity and a low standard potential producing a high cell voltage.

High specific energy and power density. Zinc has an excellent power density and is one of the most stable metals in aqueous electrolyte solutions.batt_ev

Rechargeable. Nickel-zinc and silver-zinc batteries are rechargeable. Advances are being made to develop rechargeable zinc-air batteries.

Zero emission. Zinc energy storage systems can power hearing aids, vehicles, stationary, computers and other electronic appliances 100% free of emissions.

Recyclable. Zinc can be fully recycled without loss of properties and quality and can be re-used in applications and products.

Sustainable. Rechargeable, recyclable and clean are important aspects which contribute to a sustainable future.
