This new battery charges to 70% in two minutes, and lasts for 20 years

Researchers have developed a groundbreaking new lithium ion battery that charges super quickly and lasts 10 times longer than today’s batteries. It’ll be on the market within two years.

Sick of waiting an hour for your phone to charge before you leave the house? Researchers at Nanyang Technological University in Singapore have come up with the best solution yet - a lithium ion battery that charges to 70 percent in just two minutes. 

Even better, it also lasts for 20 years, and will reportedly be available to the public within two years.

Rechargeable lithium ion batteries are already common in our mobile phones, tablets and laptops - but most only last around 500 recharge cycles, which is around two to three years of typical use. And at the moment batteries take around two hours to fully charge.

The new battery drastically improves this process, and will allow you to charge your phone while you look for your keys on the way out the door. It would also help make electric vehicles a more viable alternative to fossil-fuel-powered cars, by reducing battery replacement costs and allowing drivers to recharge their cars in minutes. 

“Electric cars will be able to increase their range dramatically, with just five minutes of charging, which is on par with the time needed to pump petrol for current cars,” said Professor Chen Xiaodong who led the study, in a press release. “Equally important, we can now drastically cut down the toxic waste generated by disposed batteries, since our batteries last 10 times longer than the current generation of lithium-ion batteries.”

The breakthrough came after the scientists replaced the traditional graphite that makes up the anode (the negative pole of the battery) in lithium-ion batteries with a new gel material made from titanium dioxide nanotubes that they created themselves.

These nanotubes are a thousand times thinner than a human hair, and they speed up the rate at which electrons and ions can transfer in and out of the batteries, allowing for super-fast charging. They also allow more energy to be packed into the batteries. This means that the battery can now offer 10,000 charging cycles, instead of the usual 500.

Even better, the new batteries will be relatively cheap, as titanium dioxide is inexpensive and already readily available in soil. The team has published details on how they formed the titanium dioxide gel in Advanced Materials, and have already had the technology licensed to eventually produce the devices. They expect they’ll be on the market within two years.

Da sigur ,in 20 de ani multe se pot schimba.....

Useless. Consumerismul în ziua de azi se bazeaz? se bazeaz? foarte mult pe uzura moral? planificat?. Dac? ai timp ?i chef te po?i uita ?i la acest documentar care trateaz? acest subiect:

De?i pare ceva ce ?ine de teorii ale conspira?iilor, în esen?? prezint? un adev?r mai mult decât evident.

 

Nu cred c? vreunui produc?tor de telefoane mobile & accesorii i-ar conveni faptul ca un consumator s? poat? beneficia de o baterie care s? ?in? 20 de ani. Totul se rezum? la vânz?ri.

Nexus 6 > turbo charging.

15 min la incarcat si tine 6h. Cel putin asa ne anunta Google si Motorola.

Destul de ok, dar cred ca bateria aia o sa-si piarda din calitate destul de repede si ajungem de unde am plecat

Foarte adevarat johnake. Ar insemna ca vanzarile de telefoane mobile sa scada drastic, ceea ce nu convine deloc producatorilor.

Nu mai fiti asa paranoici, daca v-ati cumparat telefoane SH nu cred ca v-ati plans vreodata de baterii stricate. La cat de repede se dezvolta tehnologia, uzura bateriei nu prea mai are relevanta in acest "planned obsolescence" de care vorbiti voi aici. Pot sa le faca sa fie uzate moral mult mai usor prin software si prin lipsa suportului. Uitati-va la Galaxy S3: e aparut acum 2 ani si in cazul extrem de rar in care te tine o ora poti sa-ti iei o baterie noua pentru el cu 40-50 RON, o nimica toata. "La baieti" gasesti cam in aceeasi bani pe el si Moto G, care e o investitie mult mai buna, doar din cauza softului. Majoritatea S3-urilor pe care le-am vazut acum merg extrem de prost.

 

Si nu e numai vina producatorilor de telefoane. Qualcomm, care produce procesoare pentru 90% din Androizii vanduti in vest, inceteaza suportul activ al aproape tuturor chipseturilor dupa ~2 ani. Asta inseamna ca dupa aceasta perioada, nici macar cei mai benevoli producatori (Sony/Motorola) nu ar putea sa aduca update-uri pentru modelele respective.

 

Cam asta e o parte din povestea uzurii morale. Dupa cei 2 ani, hai sa zicem 3 cel mult, devine hardware-ul obsolete, si nu planificat. Doar in cazuri foarte rare sa apare un model atat de bun incat sa tina 3 ani si sa tina pasul cu low-end-ul din anul curent. Un astfel de exemplu e Galaxy S2. Daca va uitati la celelalte varfuri de gama aparute in anul respectiv sau chiar si mai tarziu (HTC Sensation, Xperia Arc, iPhone 4) sunt complet depasite in ziua de azi. Nici macar daca s-ar vrea, nu s-ar putea face ceva in privinta modului in care ruleaza.
