Never Buy another battery again

Recent announcement by the Taiwan Co-Advanced Lithium Electrochemistry Co Ltd to increase the cycle life of LifePo4 from 2000 cycles to 5400 cycles,still maintaining 80% capacity over the life.
A double layer nano carbon coating allows olivine cathode material to be coated with different carbon compounds,the structural integrity of the material is said to be considerably improved resulting in the considerable increase in cycle life. 5400 cycles could be 20 years plus usage-I think the battery could outlast the bike.
No idea of cost,performance,density,temperature tolerance etc etc but it shows that development of lithium batteries is ongoing.

Think this is the link to their website:

Fordulike>thanks. I checked that website and they are claiming a relatively high energy density-130Wh/kg...for a 16Ah battery that would yield 576 Wh with a weight of 4.43 kg. If that is correct this could be an ideal battery for longer ranges,all dependant upon cost of course.
How does that capacity/weight compare with Lithium-Ion?
They also claim an 85% recharge in 15 mins but don't say how they have achieved that.
I will e-mail them to see if they can build a sample to fit the Kudos applications.
What do the Pedelec electrical experts make of this?

The battery that Alees manufactures is known as LFP-NCO. Their website gives a full description of the technology of this battery type but I must be honest and admit that the chemistry is beyond me-any chemists out there who can make sense of their chemistry and claims.

Hi Dave
If you do ever get these for my city bike please let me know.

300 miles on my bike and still smiling

Ahh so you have seen it also yes i posted about something like this back in May but nobody had heard of it it sounds ok if it comes to fruition

While there's no doubt that research is continuous into lithium secondary battery development, I've learnt over the last half century to be a cynic about all announcements of rechargeable battery progress. Each almost invariably proves to be either only a fraction of the advance claimed, not an advance, or completely impractical.

Not only has the basic development period of lithium use been longer than for any previous battery chemistry, the failure rates of each type entering service has been greater than any other type. They've also had the worst safety record by far.

The current basic battery chemistry prospect, Lithium Iron Phosphate (LiFePO4), was claimed to be good for ten years. In practice, up to four years maximum appears to be the case, with only two to three years in some applications. As with almost all development, the rate of progress slows as development advances and the true gains from each step now tend to be very small. Therefore I'm not expecting any big breakthrough using lithium, I think only a completely new chemistry could achieve that.

Hello Dave at Kudos,
Like you I tend towards an optimistic outlook and feel heartened by this sort of news.
I genuinely hope that this claim results in real performance increases as suggested.
With my current battery situation I appreciate that battery performance and life is the Achilles heal of Ebiking and if there is a prospect as you say of a battery which will outlive the bike itself that will give a real boost to the Ebike Industry.
I long for the day when I can purchase a Battery with these capabilities.
As long as they are produced in large quantities perhaps the price can also be low enough to enable a larger uptake of Ebikes throughout the world.
All that is required then will be a green energy source to recharge them with!
I expect that flecc's interpretation is more likely to reflect the reality of any improvement but hope that a more pessimistic outlook can be shown to be unfounded!
Barry.
