Default Thin Film Batteries??

Anyone seen these? I stumbled across them doing some research and I thought they were quite interesting.
Excellatron.com
Super light weight
4V cells
60C continuous discharge
1000C burst capable
40,000 cycles possible
Operates in temperatures from -104F to 302F
SAFE-no gassing or venting or exploding
At 300*F after 200 cycles expect 20% loss of capacity

If these numbers are accurate this will be sick. I just hope some of the technology will trickle down to us pee-ons in the battery world.

Interesting. Wonder how well it scales up?

I only saw capacities of 0.1 to 10mAh mentioned. From the size listed for the 1mAh if my ‘rithmetic is close you could only get about 115mAh in a typical 2S 1/10 pack. But who knows, lithiums sure have improved a lot in a few years, other types before that too.

In any event there is certainly a lot of money & brains chasing better batteries for a lot of reasons/uses, I have little doubt that we will continue to see advances. The future of electric RC will be interesting I’m sure.

Me, I’m betting on dilithium crystals!

I think your math is correct for the thickness of 100cells + or - a few, but the length is only 5cm so I guess if we use a 2s300p pack we can get a little higher! And like you said it is very new so there is lots of room to improve.

Did you catch the lithium air batteries on there as well? Those look pretty neat. The active cathode is actually ambient air! I can see it now, future racecars with superchargers forcing air into the battery to make it produce more power!

What chemistry is this?

Looks like they are using lithium with different metals. No polymers
