Imagine a battery for your phone that will charge to 70% full in two minutes, and last for 20 years

Imagine a battery for your phone that will charge to 70% full in two minutes, and last for 20 years
Imagine having a battery inside your phone that can quickly recharge to 70% full in two minutes. Now, imagine that this cell will last 20 years before requiring a replacement. These are some of the specs of the lithium ion batteries being developed at Nanyang Technology University. This is accomplished by speeding up the chemical reactions inside the cell.

Instead of using a graphite anode, this battery uses a titanium dioxide nanotubes anode. This allows the battery to offer 10,000 charging cycles as opposed to the usual 500. And these smaller titanium tubes are cheap and easy to make. The material is found naturally in soil and is commonly used as a food additive or to absorb UV rays in sunscreens. Converting the titanium dioxide from its spherical shape into the thin nanotubes (a thousand times thinner than the diameter of a human hair) is what allows the chemical reactions to run faster.

The new cells could be ready to hit commercial markets by 2016. According to one estimate, the market for lithium ion batteries will be $23.4 billion in two years. These longer-lasting batteries should find a home in smartphones and could make it easier for you to hold on to that handset that you've had for a couple of years, that you don't want to send back to the manufacturer for a new battery.

The technology has already been licensed, and will eventually go into production.

its about time we had a good battery in a smart phone. bring it on!

new invention so it will cost too much......

it says in the article that they're cheaper to make. Or at least the tubes are

You have heard of Apple right? They will add the logo and charge double!

oh no I think they like there idevices to run flat half way though the day, probably listed as a feature

Not just feature, another patent coming.

the iflat phone, extra £100 for a smaller battery "upgrade"

And then sue NTU! It's an iBattery!

And then sue anyone who uses anything similar. I swear their stocks are worth, what they are because of their legal team.

I may sound stupid, but why haven't solar powered batteries been used, like they were done on calculators? Phones will always be charging when light is available and many problems will be eliminated that way, Again, forgive an ignorant but honest question.

no good place to put the solar panel and they out put a tiny current and voltage. just not enough to power a smart phone

The problem is, an average smartphone uses way more power than a basic calculator. The solar panel could help to recharge some of the battery, but it won't be able to keep it running. However, maybe there will be a day that the solar panel technology is so good that we don't need another kind of power source anymore. Furthermore, most people keep their phones in the pockets, bags, or purses, there isn't really any chance for the solar panel to work.

a calculator uses .000001% the energy a modern cellphone uses...

A solar panel wouldn't charge in your pocket...

there has been phones that use solar panels on their back cover but those days are the days when 3 inch phones were the norm, not 5 inches and by the way most people use phones indoor or put their phones in their pocket etc.. when it's not in use so your opinion is really just not possible

So you are saying if they develop a 5,000 mAh battery that can be charged to 70% for about 5 minutes? TAKE MY MONEY!!

No, they can't take your money unless they shut up first.

Take my money please :( I want that battery in my phone

I registered just so I can tell you that you've made my day haha. Now if I ever go to a Fry's electronics, I'm going to be thinking of Philip j. Fry.

Thats insane but the price of a phone with that battery would be pretty high i guess.

The article did mention is cheaper to produce this type of battery :D

Didn't anyone read that the battery is much cheaper to produce.

Cheaper to produce doesn't mean it will reduce retail price. It's a new and improved technology, and you can be certain that the marketing departments involved will focus on the "better" aspect instead of the "cheaper" aspect when selling you on their new phones. The cheaper part is for them, for profits.

Agreed, and as we know have removable batteries know, batteries change every year with each new phone model. The cell may last 20 years, but the cell phone won't.

The problem is IIRC they reported on this years ago. We always hear about this kind of thing, but it never seems to come to fruition.

Exactly. It's not going to happen. To much money is made in recycling the sales. No one would hardly ever have to purchase batteries again. How would the battery industry feel about this? The Fortune500 controls the world wealth. Many of these companies are part of this structure. No battery sales equals going out of business. Develope an automobile to go far more than 46mpg? My '82 toyota got 48. Here we are 30 years later with far more technology and only getting close to this? John B.

Exactly. The reason why quality has gone downhill isn't because of any freak occurrence. It was a business decision because if you make something that works without issue for long periods of time, all they get is that onetime sale. But if they engineer planned faults into the product that will need to be fixed or require replacement of the product, they get more revenue. They seem to be following the idea "Get them on the back end". Another reason is cutting manufacturing to hit a low price point. No only do they lower the production cost, but if it fails due to that, they have another device they'd be happy to sell you. But I don't necessarily see this as being on the smartphone OEMS. If they could have a battery that lasted longer, it would be a major selling point and eliminate certain issues that they can't overcome with current battery tech. I believe this lies squarely with battery manufacturers. Something like this could cut their sales by 10 times what they're getting now, assuming most batteries last 2 years, which many don't.
