CNBC & Battery Tech


Dartagnan

Featured Posts

Yesterday I saw a clip for a TV programme on CNBC which made reference to a new technology which will be able to accept a charge 1000 times faster than lithium.  It’s broadcast at 10pm on Thursday 7th June and it is called ‘The Edge’.  

May be of interest to some.

Apologies but I just realised I posted about this previously.  Proof if it were ever needed than I have exceptionally poo short term memory.  ?

Sounds like it will be capacitor based

All a bit odd really, as lithium accepts massive charge rates anyway.

 

The limit on charging lithiums is usually all to do with current capacity of the source of the charge, rather than the batteries.

 

And the same limits will apply to any other new type of battery.

In addition, I presume this is going to be aimed at cars, the infrastructure (local as well as the grid it self) won’t be able to cope with filling multiple cars at that rate unless some kind of local storage buffer was implemented.

Yes. Electric cars are not ubiquitous for want of suitable battery technology, we have that already.

 

It is the charging technology that is missing. 

 

Politicians will be the last to figure this out. 

 

Nobody here needs to watch the telly programme, now I've explained :D

Of course if it has at least the same energy density as lithium the application in devices like mobile phones and all the other gadgets will be good.

Yes. My posts in this thread pre-suppose the programme will be about electric car batteries, which is not what the OP says. You are quite right, it would be brilliant to charge my phone at 100A for 0.6 of a second instead of 0.5A for two hours.

 

Edit to add:

 

Ok ok, I got my arithmetic wrong!!

I believe that this story is based on the concept of quantum batteries. If instead of moving ions around these are replaced by electronic bits that are either charged or not. Felix Binder, quoted in New Scientist, has shown that if these bits are 'entangled' the amount of energy needed for a full charge scales with the square root of their number and not linearly as in classical batteries, including lithium ones. Apparently this means that a quantum battery with 1 million bits would be fully charged in the same time as a 1000 bit classical battery. I assume that this supposes the same charge acceptance rates. The scaling of this concept to produce a usable battery will take some years however. Regards, HughC.

That doesn’t make sense to me. It suggests that you put back less than you take out. That would be the world’s energy problem sorted overnight.

I have always believed the old adage that if you think you understand quantum mechanics then you are not studying it deeply enough. In some situations entangled particles will, I am led to believe, when returning from a higher to a lower energy state emit more energy than classical thermodynamics predicts.The difference is very slight but that is all it needs to be. In the long term this will affect every aspect of technology. This does not I think mean that the laws of thermodynamics are wrong only that they deal with the net effect of large numbers of particles. There is a new kid on the block 'quantum thermodynamics' which I find even harder to follow than the classical route. HughC.
