In a variety of lithium battery technology to substitute, recently appeared again a new power: zinc air rechargeable batteries.

In fact, zinc air since the invention of battery technology has more than 100 years history, use adsorption the oxygen in air as positive active substances, zinc chloride or treatments in anode, for the electrolyte solution. The 1960s because the space project technical improvement, zinc air began to practical application. Now, many of the button batteries used in the hearing, is actually zinc air.

Because of zinc air structure limits, has long been unable to achieve the rechargeable battery recycling technology. But in recent years, Norway, scientific research institutions and zn electrode SINTEF through improving the internal humidity control, zinc air battery charge technology. Currently the rechargeable battery in the experiment of zinc air has achieved more than 100 times, is expected to recharge cycles can reach 200 times. Lithium battery, zinc air compared to the storage battery recharging the battery is three times, it is half the cost of lithium batteries overheating, and no explosion safety hazard.

Founded in Switzerland SINTEF ReVolt company specializing in zinc air rechargeable batteries product development and marketing. The company says, the miniature zinc air for hearing next year will start to recharge batteries can be used in mobile phone sales, and other mobile devices of zinc air will then rechargeable batteries. When the market to charge can reach to 300 life should be 500 times.

In addition, through reference to ReVolt, fuel cell structure that zinc air rechargeable batteries used in the future life of electric cars, charge, but more than 10,000 times the current is far from practical.
