Scientific advances are the result of intense research, complex protocols, gritty effort. And sometimes it’s a stroke of luck to question. Take Mya The Thai student in chemistry from the University of California. It is in building an experiment to improve the resistance of lithium batteries it has discovered entirely by chance a revolutionary new method

Computers, smartphones, tablets; Lithium batteries are everywhere and their life is well known: between 5000 and 7000 cycles on average. Then, the battery dies. Lengthen their lifespan is therefore a real challenge. And the University of California scientists working on nano-son of the implementation of these batteries to improve their resistance. Without success. Son because these are very fragile and do not allow truly extend the number of charge cycles.
“Mya
(…) Coated (nano-son) of a very thin layer of gel and
started (experience), “says Reginald Penner, president of the department
UCI chemistry. “She found that just using this gel
she could repeat the cycle hundreds of thousands of times without
lose capacity. “
In fact, while we move from 7000 cycles to 200 000 cycles at least. The unexpected experience without been renewed by the research team. The nanowire gold was placed in an envelope of manganese dioxide and lithium was replaced by an electrolyte gel. what realize that 200 000 cycles produce a degradation of battery performance … 5% .
further tests are underway to better understand the causes of this incredible life. “for now we do not yet have all included the operation of these batteries,” explains the head of search Reginald Penner. Always it is that these new batteries could benefit course smartphones but also for electric cars.
discovery could lead to market batteries for
computers, smartphones, electric cars or the
spacecraft.
