Did you noticed that over time the battery capacity of smartphones and tablets begins to decrease? What happens is that most of the batteries are lithium batteries, that after a certain number of recharges the capacity of the battery begins to drop.
However, almost unintentionally, researchers at the University of California have developed a battery capable of supporting more recharge cycles. The original experiment idea was to create a more secure and stable battery, as traditional lithium batteries can be highly flammable because of its components – is not so absurd to hear stories about smartphones exploded, acting as if they were real bombs.
Thinking about it, the team of researchers has developed a battery with gold nanowires to store electricity, coated with manganese oxide and then protected with an electrolyte gel. This junction prevents corrosion and allows the metal layer to become more resistant, in addition to maintaining stable temperature, the results were surprising. The developed battery is capable of supporting 200,000 recharges without affecting its battery life.
This figure suggests a capacity 400 times higher compared to the use of traditional batteries. Scientists still do not understand exactly why the increased resistance and there is no provision for the development of battery for commercial purposes, one reason being the use of gold nanowire that despite being tiny can be a more expensive product. On the subject, Reginald Penner, leader of the research team suggests it can be possible to use other materials, such as nickel if the technology will be expanded to become a product on the market.
