Emerging Technology & The 5-Minute Charge

n97 mini

It's become clear that Li-Ion technology can't deliver a five-minute charge, otherwise the latest Samsung Galaxy would have it already.

I keep a passive eye on emerging battery technologies, but aside from Sodium batteries, which should be hugely cheaper but no quicker, I can't see any obvious candidates.

Anyone feel like backing a horse?

I dont think any such thing is clear at all

If you can tell me about a Li-Ion battery in a commercial product that can do a 90% charge in 5 minutes, at least 2000 times, I'm all ears!

My observation is that even the latest mobile phones with fast charging can't gain that significant a charge in less than 30 mins.

If we limited all possibilities to what was technically possible now, there would be no improvements anywhere. What would the world be like if someone had your viewpoint 250 years ago. We'd be bemoaning the shortage of whale oil I'd say

We're at peak whale!

Li can be charged exceedingly quickly , in the lab , we charged them in 30 seconds ( small LI )

The problem is charge termination and issues around any fault in the battery as well as heat gain , any failure results in explosion !

SO manufactures play it safe and design in controls and limits

also its a function of cost, high power charging in a mobile device would add considerable costs

so its not necessarily a technological issue per se

Oi, we moved to Nickel Metal Hydride because Nickel Cadmium wasn't good enough. NiMH has faded because Li-ion is much better. I don't believe battery evolution will stop at Li-Ion as, like the others, it's not perfect.

of course not, but battery tech is slow to materialise, rechargeable LI is around for over 30 years ( 1976 ) its not " new" tech

There are several candidates for next gen batteries solid state Li, Sodium, Silicon
but again it takes time to get the tech sorted

whats clear is that BEVs are the future, that decision has been taken, everything else is dropping by the wayside

Changing battery tech still leaves us with a BEV

we moved away from NIMH due to patent issues, and the subsequent Li advances. LI Ion batteries are around for decades. Not new tech.

The next stage is rumoured - for some time - for LI-Air "solid state" batteries. Theoretically it has the same properties as ICE as regards energy density, energy per stored wait, and recharge times. However it has been around a while and has not been made viable. Yet.

Seems like it really, the last 18-24 months have seen a massive shift both in terms of policy and also the manufacturers themselves.
