Toshiba SCiB cells due out in March

[ChrisBarron]

Apologies if someone esle reported on this.

A couple of years ago Toshiba released a statement about a high capacity cell, which looked in the photo like a tagged PP3 battery.

It seems they are now all set to sell these into non-CE applications from March, into hybrids and so on.

5,000+ recharge cycles, and a 90% charge in under 5 mins.

The cells are beign sold as individual 2.4V 4.2Ah cells or, better still, as a packs of ten to make 24V 4.2Ah packs, measuring 300mmX100mmX45mm, with built in BMS, weighing 2kg

I doubt they will go retail in the near future but there is always hope !

Hi Chris

A 90% charge in 5 minutes sounds great, but the problem is finding a charger or mains supply that can deliver that rate for a decent-sized pack.

The energy density isn't brilliant even if it does include a BMS: 24V and 4.2Ah at a weight of 2 kilos is about 50 Wh/kg. That compares with around 80 Wh/kg for LiFePO4 (A123, LifeBatt and some Thundersky) and even higher figures for lithium polymer (Kokam).

Yes it was already reported over on the main site (Click to see here ) There's another posting about another new battery which looks destined for hybrids on the home page now too. You see there's always little gems of news on the main site you can bookmark the home page or subscribe to the RSS feed and then you're always up to date on news thanks to the BVS website contributors

Yeah I know about those, but was taken by the lifetime claims more than anything. Maybe as much as ten times the life of lithium means I think it could find a few applications where size isn't the largest of issues.

The one I'm really looking forward to is the new Stanford Lithium cell based on nanotech fibres, I might be a fair bit greyer when they come out though, as previously reported on the main page http://tinyurl.com/2slvyq
I just hope they aren't in one fo those inter-university development one-upmanship battles, it would be a shame if that were the case but it looks at first glance to be a respactable claim

I see that Schwinn are now using the Toshiba Super Charge (SCiB) battery on their e-bike. Interesting to see how long (or do I mean how quick?) these things take from announcement to the market now.
