batteries: the power behind the phone - li ion battery cell

Technology develops at such an exciting pace, and sometimes it's hard to keep up-just ask the battery, the unexposed brick under our 24-year-old Hoodhour, connect-
Any society.
They did heroic work to make our touch screens shine, to make our laptops buzz, to make our phones ring, but in the race to keep up with their powered devices, the battery
"Wait a minute," you said. "My phone is running out of power.
"Ten years ago, when your old brick continued to jam for a week between charging, the phone had no power to check football scores, shoot videos or play Scrabble in Korea.
It's not surprising that these things squeeze more juice out of our batteries.
"We 've seen tremendous advances in technology-better processors, more memory, and larger disc drives," said Adam Liqi, a mobile expert at technology analyst Ovum . ".
"But the only improvement we see is the battery.
They are a big technical barrier.
"Apple is expected to release its latest tablet product next week.
The biggest question is expected: What is it doing, what is its cost-what is the battery life?
With the motorcade of electric cars quietly starting their batteries
Power engine, the demand for our batteries will only increase.
So, there are two more questions: why is it difficult for us to keep up with our power?
What are the white people in the world?
What about things with batteries? Forty-
Five years ago, at least for most people, chips were only fish, and a man named Gordon Moore wrote a paper in which he said, the number of transistors that can be compressed in an integrated circuit is about doubled every two years.
Three years later, Moore
Founded Intel, Intel's computer chips have grown almost exactly at the dizzying pace he predicted.
Today, the Intel microprocessor has more than one billion transistors, and the packages of these transistors are very dense, and you can install 2 million of the things in the complete-
Stop at the end of this sentence.
What is called Moore's law drives exponential growth in the digital revolution-the more transistors you can encapsulate into a circuit, the faster and stronger its chips can run, while maintaining
However, the batteries that keep these circuits connected are not digital and still work according to the basic principles developed more than 200 years ago.
In the 1780 s, Italian physicist Luigi Galvani found that when a dead frog used two pieces of metal, his legs would jump alive.
Galvani created a rough track that was accepted by his friend, Noble professor Alessandro Volta.
He used frogs for salt water.
An alternate stack of dipped paper and metal sheets of zinc and copper plates.
Volta created the world's first modern battery.
According to the simplest definition, the battery is still a device that converts the stored chemical energy into electric energy.
A chemical reaction occurs in a series of batteries, separating the negative electrode and the positive electrode with a conductive electrolyte.
When you connect the battery, positively charged ions "swim" from the negative pole to the positive, prompting the negatively charged electrons to power the torch bulb or iPhone screen.
This is a chemical process where you can't shrink chemistry at a certain point.
Peter Bruce, a chemistry professor at the University of St. Andrew, said that while computer performance actually doubled every two years, the energy density of the battery increased by five times in about 100.
"If you want to store more energy, you really have to develop new materials and new concepts," he said . ".
"It's not just making the same thing smaller.
"Bruce is one of the many scientists competing to get more information from modern batteries.
Not only did he owe Walta, but he owed him a favor, and his work in the 1970 s gave us modern rechargeable batteries for almost all our gadgets.
Stan Whittingham of England
Born American chemist, who studied at Oxford University in his 1960 s and worked in the research department of oil giant Exxon, when he realized excellent energy
The storage properties of the lithium element make it an ideal material for rechargeable batteries. "A lithium-
The ion battery has about five times the energy of the lead battery, "Whittingham said on a phone call from Binghamton University in New York, where he is a professor of chemistry.
"It's really a technology that excites a lot of people --changing idea.
No lithium.
If it's an ion battery, you won't have an iPod or a cell phone.
They give us a lot, but of course people want more.
Bruce is meeting the challenge with his "air"
Rechargeable lithium battery.
In short, the stair unit (
St. Andrew air force base)
Use reagents that are more complex than air in batteries than expensive chemicals.
By releasing space and taking advantage of one of the free few elements, Bruce's cells can squeeze more energy into smaller spaces at a lower cost.
"By using air in cells, we can get up to 10 times higher energy storage," Bruce said . ".
"It's exciting because it's hard to improve the lithium ion battery, except for double.
"The storage capacity of the battery is 10 times that of the battery that powers the phone and will be restored to the day when the phone is charged every week.
At the same time, other scientists are working to solve another major problem with modern batteries-the time it takes to charge.
Gerbrand Ceder at MIT (MIT)
Always thinking about improving the way lithium ions themselves move through the battery-the faster they "swim", the faster they charge the battery.
Ceder and his team manipulate the materials inside the battery to make the ion channels smoother and watch them drive at incredible speeds.
Ceder estimates that prototype batteries manufactured using the process can be charged in hours or even minutes, but can be charged in seconds.
"If we can shorten the charging time from two hours to one hour, you may also finish charging overnight," he said . ".
"But if it's a minute, you'll be standing by and waiting-it's like cheering your car or having a cup of coffee.
"Ceder also works with a team that uses genes --
Design viruses to build positive and negative ends of lithiumion battery.
The new battery will be more flexible and efficient than the existing technology, but, like MIT's fast-
Charge the battery and Bruce's stair battery, they are very much on the drawing board of the lab.
This is a measure of the greatness of modern batteries and the challenges faced by developers, as Whittingham said (
Maybe a kind of pride)
: "It's just lithium for at least the next five years.
At the same time, manufacturers are racing to launch energy --
Efficient screens and hardware with less demand for batteries.
But with the coming of the next major breakthrough, it's only a matter of time before we get the battery suitable for the next generation of gadgets and cars.
For those of us who are increasingly tied to mobile phone chargers, time is not fast enough.
More vibration from Volt: how to improve the battery, keep it clean, and save power is all about efficiency, if the cooling fan in your laptop has to work overtime because your vents are blocked by dusty cookies, don't be surprised if your battery fails at critical moments.
Being able to play games and find the nearest Pizza Hut is such a great reason for modern phones, but many apps are terrible power consumption.
The same is true of laptops.
Maintain minimum use and activate any-
App settings that can save juice.
Aircraft movement and lock-in mobile phone networks are a difficult task for mobile phones.
If you are in a place where there is no or low coverage, take your phone out of the shutdown statethe-
Grid pain, switch to airplane mode.
Closing 3g where data coverage is incomplete also helps.
It's not surprising that your gadget will consume less energy if it falls asleep.
Develop the habit of playing hibernate, and if you can, shorten the time required for the mobile phone to switch to sleep mode.
Hi, I was thinking.
To power the larger screens on mobile phones and laptops, the tech battery has stopped working.
Some screens account for more than third of power use, so reducing brightness increases battery life.
When your hard drive gets cluttered and requires more power to keep it running, it quickly becomes inefficient.
Use the defragmenting app to clean things up and improve performance and battery life again and again.
Almost every smartphone app "wants to use your current location ".
Usually it's useful, but the GPS receiver in your device requires a lot of power, so consider hitting "no thanks ".
Minimize the use of map applications.
Make small electrons upstream and downstream of your battery feel useful, so give them some love.
Continue to use your device and experience at least one full charge cycle per month.
Keeping the battery in a drawer is neither happy nor efficient.
