Designing a Safer Battery for Smartphones (That Won’t Catch Fire)
Mike Zimmerman likes to rock his guests with a hammer through solid polymer lithium metal batteries.
This is a good thing. Mr.
Zimmerman\'s battery is a new spin of lithium-
Ion batteries are widely used in smart phones, cars and other products.
As anyone concerned about Samsung\'s recent problems with flammable smartphones may know, ion batteries can be time bombs.
If there is some kind of short circuit, the liquid in them will burn.
It is absolutely not recommended to DingTalk one of them.
With that in mind, sir.
Zimmerman\'s presentation caught the attention of people.
Quality, he wo. , start-
Ion materials are cutting-edge products for designing safer batteries.
The company is developing \"solid\" lithium polymer batteries that can greatly reduce the flammable properties.
Solid lithium polymer metal battery-
When it arrives in business
It will also make electronic designers more creative as they will be able to use plastic-like materials (polymers) that allow smaller, more flexible packaging and require less complex safety mechanisms ).
\"My dream is to create the holy grail of solid batteries . \"Zimmerman said.
After four years of development, he believes he is close and hopes to start manufacturing in the next two years.
Ionic materials is one of the new wave of academic and commercial research in the United States, Europe and Asia, aiming to find safer battery technology because consumers have higher performance requirements for mobile phones and cars.
Last year, rival U. S. solid polymer battery manufacturers Seeo and Sakti were acquired by German industrial company Bosch and British vacuum manufacturer Dyson.
In September, the agency that the US Department of Energy supported the next phase of research highlighted interest in solid cells
Power generation energy technologies has announced 16 awards aimed at accelerating the development of solid cell technology, including a $3 million contract for ionic materials.
There is growing evidence that, after decades of extremely slow development, batteries are on the verge of yielding to a new generation of material science.
Historically, the battery is a clear exception to the progress index --by-
Computer processing and storage.
In fact, only a few rechargeable battery chemicals have been heavily used in the past 150.
\"This is a huge challenge,\" said Ilan Gurr, director of the rotary accelerator Road, a support energy project.

\"The improvement of the battery is very slow, and the improvement of the battery chemistry is very difficult.
\"He pointed out that the battery has been disappointing for more than a century.
Thomas Edison expressed his frustration with the technology in an interview in 1883: \"The battery is one of the special things that appeal to imagination, and it is impossible for stock scammers to be more perfect than that.
\"Modern consumer electronics designers are not optimistic.
\"The only real breakthrough battery technology I \'ve seen in my career is lithium-
Years ago, \"said Tony Fader, an electrical engineer who led the design of the iPod and the original iPhone at Apple before starting home thermostat maker Nest.
\"Sometimes it feels like a Captain Ahab --like quest. ”Lithium-
Sony\'s commercial ion battery in 1991 has a significant advantage over the existing nickel battery.
In terms of tightness and recharging, the CD rechargeable battery.
But they are also likely to have two failures that forced the consumer electronics industry to make a massive recall.
Since 2000, Sony has encountered a series of problems in the battery fire, and finally recalled 4 units.
2006 laptop battery Section 2 million-
This is by far the largest recall of consumer electronics.
Samsung\'s Galaxy Note 7 was recalled this fall.
Smartphones, bring flammable batteries back to the news.
Customers around the world say the phone is on fire.
It is not clear why this happened.
A Samsung spokesman said the company had not completed an assessment of the cause of the battery failure.
Many battery experts say they believe the fault lies in the fact that Korean electronics wants to make thinner battery packs, thus designing ultra-thin separators designed to prevent the safety of direct contact with battery electrodes.
This can cause a short circuit, causing a fire or explosion.
This use of liquid electrolyte is a potential defect inherent in lithiumion batteries.
They are based on liquid electrolyte, a material used to ensure that ions or charged particles move between electrodes during battery charging and discharge.
For more than a decade, people have been looking for an unstable alternative solid material.
People are optimistic about new solid polymers that may replace liquid electrolyte, but they are not turning to commercial --
In addition to the lithium polymer battery that French electric vehicle manufacturer bolllore is now using.
But the technology is for electric car batteries, and it doesn\'t run at room temperature.
It takes about 192 degrees to warm up.
So far, this is the case with almost all lithium metal polymer batteries.
Room temperature operation is only one of the potential advantages claimed by ionic materials.
Its new polymer is also able to efficiently shuttle ions between the battery cathode and the electrode, as the liquid electrolyte currently does, or even more efficiently. Mr.
Zimmerman\'s background is in the field of semiconductors;
He works at Bell Labs and then at a company called Quantum Leap Packaging.
Several university researchers working with the company believe that this will give him access to a technology that can be manufactured more than the competitive polymer and ceramic battery technology currently being explored.
Jay Whitacre, a physicist at Carnegie Mellon University, said: \"Mike and his family are so interesting that they are using known production technologies borrowed from the semiconductor packaging industry . \" He was involved in the research at the beginning of the ionic material, and is now the chief scientist of Aquion Energy, a manufacturer of household storage and industrial batteries based in Mt. Pleasant, Pa.
The new progress has led some technicians in the field to believe that batteries may eventually get out of the woods.
\"We are in the golden age of new chemical development, which may have not been around for 30 or 40 years since the last energy crisis,\" said Paul Albert . \", Project manager of the Department of Energy\'s senior Research Project Agency-Energy.
\"Developing energy storage technology is a very exciting time.
