Your phone's battery might be fast drying up that a power bank was invented to aid that problem, but out of accident, a student has created a better option.
Mya Le Thai, student of the University of California, accidentally invented a smart phone battery that can last for at least 400 years.
While playing around in their lab with her team, they was able to produce a thin strip that could withstand 200,000 charging cycles in three months without deterioration.
Widely used lithium-ion batteries today apparently tear out easily after 7,000 charging cycles at most.
All they did was to enclose golden nanowire material in a special electrolyte gel to protect it from deterioration.
The accidental invention may lead us to a future without charger and powerbanks, reduced toxic battery production, lower monthly electricity consumption, and a good heirloom to your grandchildren.
The production of the new invention will be started as soon as scientists find cheaper alternatives to create a marketable one.
