New battery with zinc works three times longer than lithium-ion

Today, rechargeable batteries are used in a vast variety of modern devices, from computers and mobile phones to cars. In order to improve the efficiency of batteries is constantly carried out to develop new technologies that will extend battery life and improve the security of electronic devices. For a long time remained the most popular lithium ion batteries. However, this technology is far from perfect. For example, several years ago as a result of overheating batteries for laptop notebook manufacturers have been forced to recall its products, to prevent possible fire.

Currently developed a more secure technology - the so-called air-zinc batteries. They are half price and much more powerful than their predecessors. According to researchers, they provide three times more energy than lithium-ion batteries.

Zinc-air batteries were developed by the Norwegian Institute called SINTEF. Sales of batteries the company will ReVolt, which plans to release an air-zinc batteries on sale as early as next year. First, young models will be available for headphones, and later appear larger batteries for mobile phones.
