Discovery could open the door to cellphone and car batteries that last five times longer

For example, at one-fifth the cost and weight of those presently on the market, a lithium-air battery would allow an electric car to drive 400 miles on a single charge and a mobile phone to last a week without recharging.............................

...and hopefully laptops. My Sony Vaio which I otherwise really like, lasts less than two hours...

Five to ten years? What’s the point?...

[Red Badger]

They always say that, but if it is a real breakthrough, it will accelerate rapidly.....................

Great discovery. Of course it will take a while to use this commercially, but still, it is very encouraging.

Great, but where are the laser guns and the flying cars?

Sixteen years ago I found a small radio, 9x5inches, it had already been sitting in the garage for six years, but it turned on and worked. Its been sitting at my desk for 16years, every few months I turn it on, the batteries have Never Been Changed?

It shows that the problem is not insurmountable, and could lead other researchers into a new direction.....................

Is it solar powered?...................

We already know Dlithium crystals are the answer, why don’t they go ahead and use them? Protectionist racket by the litihium ion guild is my guess.

It will happen around the time the pill that you put in your gas tank to increase mileage really works.

No, not Solar. The brand is a “Sound Sonic”, it runs on 3 Duracell batteries.

Good quality alkalines, haven’t leaked. Shelf life often given as ten years. The small radio doesn’t draw much current which helps.

I still have some truck/marine batteries 11 years old that still test good (used in a solar bank). A few have failed in the same bank although all were subject to the same conditions.

#8 Have you noticed a very old hamster on a wheel inside the radio? : )

[SunkenCiv]

And how many times has there been such a discovery in, say, the past five years? That explains why all our batteries last so much longer now. /s Thanks Red Badger.

Yeah, I know. Its actually fun, this thing will outlive me...

Interesting info.

I hear they're quite common on some planets:
