I just heard about Sulfur Selenium solid state chemistry developed by NASA, apparently in development for a few years...

Okay, did the analysis. We reboot elasticsearch ( xenforo requires it for search functionality ) every midnight because it's super...

I was thinking about putting bearings in the sprockets so they rotate independent of the shaft. The two sprockets would be joined so...

I don't know if anyone has done it but it seems as if it should work, other than possible clearance issues of fitting 2 sprockets...

So you yourself have tested the capacity? That's what I'm looking for. Cycle life in the real world is yet to be determined I guess.

I was looking for capacity and cycle life testing of the 370Wh/kg cells.

I found some testing in this video here. It's made by a Chinese ev tech news network. Their process appears to be pretty scientific, but...

Is there third party test data on these cells?

[Added to original post] Has anyone ever use the swingarm pivot axel as a jackshaft to transmit drive power? Wondering if this can be...

Welion and Qingtao now selling semi-solid batteries a la cart on Taobao Alibaba... probably on AliExpress soon. These are NCM...

Depends, if I have more range and don't need to stop and charge at all then the range is better than fast charging. Also I don't see...

I think I mentioned this on another post a while back, regarding access to forum features being different between platforms (pc, tablet...

What high performance EV has limited acceleration because of pack output instead of traction? Tesla doesn't seem to have any problem...

Except the high energy density batteries keep the weight lower and by increasing the kWh of the pack even a lower C rate chemistry can...

A 300 Wh/kg cell with 700 cycles could easily make a 500 mile EV, 700 x 500 = 350,000 miles, which is longer than most vehicles last...
