[Phys.org]New nanostructure for batteries keeps going and going

(Phys.org) -- For more than a decade, scientists have tried to improve lithium-based batteries by replacing the graphite in one terminal with silicon, which can store 10 times more charge. But after just a few charge/discharge cycles, the silicon structure would crack and crumble, rendering the battery useless.

Now a team led by materials scientist Yi Cui of Stanford and SLAC has found a solution: a cleverly designed double-walled nanostructure that lasts more than 6,000 cycles, far more than needed by electric vehicles or mobile electronics.

The future is bright, and long lasting.

 

I had to make up my own title as the article title is rubbish.

Duracell reference... I think.

Either way, pretty cool. Cannot wait for this to start getting applied to different products.

Or hours instead of minutes in the case of some.

"lasts more than 6,000 cycles, far more than needed..."

6000 cycles is 16 years at one charge per day. Which is nice compared to anything made today, but still short of what I want stuff to last. I think I must be the only person who thinks stuff should last a good 20 years or more without breaking or wearing out.

I hate how everything is made to last as short a time as possible. It sucks having to replace stuff just as I'm getting used to it. like my mouse... it's only 5 or 6 years old and the charging connection has to be wiggled and jostled endlessly to get it to connect and the left button is starting to stick and multi-click all the time. So I'm going to need to replace it and there's no way this style that I like is still being made. It'll be impossible to find something that's laid out in the exact same way, the way that I'm used to and like. I would happily pay twice as much (or more) for electronics like mice or keyboards that are guaranteed to last 10+ years. (or razors, or clippers, or headphones, or walkmans, or flashlights, or stereos, or UPS's, or ...)

Cars are too stupidly expensive as is to justify a price increase for increased lifespan, but they should still be better built and last longer. Stupid cars.
