Researchers Wang Changan, the Tsinghua University in Beijing, and Li Ju, the Massachusetts Institute of Technology, made a discovery that may allow the batteries of mobile devices of the future have a lifetime four times higher than current. To do this, recourse to chemical components that make batteries lose their charge capacities much more slowly than what happens nowadays.
Interestingly, scientists have reached these findings almost by accident . According to the Tech Radar , the duo was looking at ways to remove the coating of aluminum oxide nanoparticles. By studying nanoparticles, the researchers found that they could protect them by using conductive material titanium oxide which in this case replaces the graphite anodes which are usually found in traditional lithium-ion battery. As the graphite anodes contract and expand when the battery supplies power to the device, this process leads to battery will become less effective over time.
Wang Changan and Li Ju built based batteries the new nanoparticles and found that after 500 charge cycles, they held four times more capacity than traditional lithium-ion battery that were subject to the same tests.
It should be noted that this finding does not mean that batteries may have a four times greater autonomy, it is able to have a longer life cycle, ie, will endure longer without having to change them.
