Till date, most lithium batteries that we use in our devices for daily use, should last to few years. As one major issue to this type of batteries is when charging and discharging them a small bit of corrosion shows up inside of them, increasing over few years time. We are reading, hearing tips and guides on the web, social networks, people who talk about that particular subject as for some major questions are:
“How do we properly treat batteries so they will last longer? Which will be the improper care and How do we evade lifespan decreasing?”
There is lot of trouble finding the right answer with all these information available, circling around.
The 40-80% rule, inadvisable to leave it fully charged.
Lithium-ion batteries are best left at around 40-80% charge. There seems to be our major issue with this factor, since we’re all occasionally leaving our lithium battery to fully charge, or in many situations, when we don’t have power output nearby leaving it below 40%
Fully discharge it once a month.
Might seem strange as it sounds but many manufacturers actually advice that discharging our battery once a month, as it can lead to correct and accurate showing.
Keep it cool.
Extensive heat as a leading factor to reducing of lithium battery lifespan. Keeping it cold while we can and is one of the things we can do to prolong the lifetime of our lithium batteries.
We would have guessed that some clever bunch of people would try and do what we ultimately want, Batteries that will last few hundred times longer with a long lifetime. A breakthrough in battery technology.
Well that seems to have happened. Researchers at the University of California figured out a way and invented a battery material that its nanowire-based with some very important factors considered as pros:
They should last around 400times as longer, can be recharged few thousands times more than that some of the best batteries can offer on our current market, and it might lead to heavy production of batteries for commercial use.
Playing with nanowire-tech and implementation in batteries has been long tried by scientists. With properties such as high conductivity and a large area available that can be used by movement of electrons and used as storage of them, nanowires are considered an ideal material for battery use, although their fragility is always considered as main issue for continuous recharging.
UCI researchers’s solution to this problem came by experimentation by one of the UCI doctoral candidates, her name Mya Le Thai as she was testing the electrode by cycling the process over few months time, with more than 200,000 retried times without detecting any loss of power nor any loss of capacity without damaging the small fragments of nanowires.
She have actually found ,not intentionally, that this system works without flaws, it is extremely longlasting , and resilient to failing.
The findings were published today in the American Chemical Society’s “Energy Letters”
The event going UCI chemist Reginald Penner’s Lab, Mya Le Thai did this test by suprise, and whats more interesting the chemists still don’t fully know how this mechanism works, and are going to further investigate this profound battery recharging technology and to come with better understanding for the manganese dioxide material properties.
It comes as a suprise that chemists still don’t know
Working in UCI chemist Reginald Penner’s lab, doctoral candidate Mya Le Thai is doing further research on the battery recharging technology to better understand the properties of the manganese dioxide materials.
“Mya was playing around as she coated this whole thing with a very thin gel layer and started to cycle it,” explained Reginald Penner, senior author of the study, in a press release. “She discovered that just by using this gel, she could cycle it hundreds of thousands of times without losing any capacity.”
“That was crazy,” he added, “because these things typically die in dramatic fashion after 5,000 or 6,000 or 7,000 cycles at most.”
“The coated electrode holds its shape much better, making it a more reliable option,” Thai said. “This research proves that a nanowire-based battery electrode can have a long lifetime and that we can make these kinds of batteries a reality.”
“We started to cycle the devices, and then realized that they weren’t going to die,” Penner told Popular Science. “We don’t understand the mechanism of that yet.” Read more
