Possible huge improvement in lithium cells
This is worth a look - charge to 70% in 5 minutes. Cycle life up from 3-500 cycles to 10,000.

If it over makes it out of the lab. It would seem to me that the titanium dioxide nanotubes disrupt lithium dendrite growth which is the commonest cause of death of lithium cells. If this makes it out of the lab which it might well not do.

RE: Possible huge improvement in lithium cells
There are Imren cells that claim 40A. Though they perform worse than their 38A claimed cells. Nobody seems to know whose cells are actually under the wrappers and frankly I'm dubious of claims of more than 30A continuous discharge.

These may be Imren rewraps or they may be something else. Their 35A cells on the same page are almost certainly Samsun INR18650-25R cells which do not do 35A continuous discharge.

Round cells may be close to their limits - I believe LiPo cells are the way forward. You can already buy Lipos rated to complete discharge in 20 seconds - about 400+ amps. I have a relatively low rated Lipo here that will safely do 340A and has 5800mAh capacity. It cost around $15

RE: Possible huge improvement in lithium cells
That really would be a fantastic improvement. I could see a lot of changes coming around if they do get them out. You would have laptop batteries that would outlive the laptop, manufacturers could make them built in instead of replaceable. Of course it would all depend on pricepoint.

Don, where do you get your LiPo cells, hobby king?

If the natural tendencies of mankind are so bad that it is not safe to permit people to be free, how is it that the tendencies of these organizers are always good? Do not the legislators and their appointed agents also belong to the human race? Or do they believe that they themselves are made of a finer clay than the rest of mankind?

RE: Possible huge improvement in lithium cells
They have some pretty good deals on a lot of stuff. Shipping isn't bad as long as you put together a decent sized order from them. Lot's of stuff there that is worth buying.

RE: Possible huge improvement in lithium cells
A tip with Hobby King is to keep looking at an item for a while - a box will often appear offering a better price. Worth a couple of minutes of staring at the page. Smile
