Inventing a smartphone battery that recharges in one minute

<p style=";text-align:left;direction:ltr">ArabiaWeather.com - Scientists from Stanford University in California have created a battery made of aluminum for use in smartphones. They&#39;re cheap, long-lasting, flexible, and recharge in just one minute.</p><p style=";text-align:left;direction:ltr"></p><p style=";text-align:left;direction:ltr"> The scientific journal &quot;Nature&quot; published the details of the new invention, and indicated that the new &quot;aluminum-ion&quot; battery will replace the &quot;lithium-ion&quot; batteries used in millions of personal computers and mobile phones.</p><p style=";text-align:left;direction:ltr"></p><p style=";text-align:left;direction:ltr"> Chemistry professor Hong Ji Dai, who supervised the research, confirmed that the new battery is fast charging and safer than the currently used lithium-ion batteries, which sometimes explode.</p><p style=";text-align:left;direction:ltr"></p><p style=";text-align:left;direction:ltr"> It is noteworthy that scientists have tried for a long time to make batteries out of aluminum, which is a relatively cheap and lightweight metal characterized by a high charging capacity, but they were unsuccessful, until the scientist &quot;Day&quot; was able to discover that graphite was the opposite pole of aluminum.</p><p style=";text-align:left;direction:ltr"> In the prototype of the new battery, aluminum represents the negatively charged electrode, or anode, while graphite is the positively charged electrode, or cathode.</p><p style=";text-align:left;direction:ltr"></p><p style=";text-align:left;direction:ltr"> <strong>See more:</strong></p><p style=";text-align:left;direction:ltr"></p><p style=";text-align:left;direction:ltr"> <a href="http://www.arabiaweather.com/content/كيف-تصنع-قطاراً-كهربائياً-باستخدام-مغناطيس-وسلك-نحاسي؟"><strong>How to make an electric train using a magnet and copper wire?</strong></a></p><p style=";text-align:left;direction:ltr"></p><p style=";text-align:left;direction:ltr"><a href="http://www.arabiaweather.com/content/كيف-تحافظ-على-بطارية-الهاتف؟"><strong>How do you maintain the phone battery?</strong></a></p><p style=";text-align:left;direction:ltr"></p><p style=";text-align:left;direction:ltr"> <strong><a href="http://www.arabiaweather.com/content/طريقة-مبتكرة-لإشعال-النار-دون-استخدام-الكبريت-أو-الغاز">An innovative way to start a fire without the use of matches or gas</a></strong></p><p style=";text-align:left;direction:ltr"></p>
