Sodium Ion extreme discharge test!!!!

In this video I will discharge a fully charged Sodium Ion cell down to zero volts or as low as it will allow. I will fully recharge it again at the recommended maximum charge current (in this case 1C) and complete another normal (0.5C) discharge to see if any adverse affects have occurred to the cell. I will monitor the temperature of the cell as well. This test should confirm that this is truly a Sodium Ion cell and not a cheap lithium ion cell relabelled as Sodium.

Hello again, it seems the batterys can perform very well in cold conditions maybe you can try put some in the fridge - like minus 20⁰c - and test how they perform as stated 90% capacity. Good luck 🍀

This is absolutely excellent work. Can you do a few cell cycles to see how they age?

I thought about to use it for my scooter - but in my opinion the drop of voltage is a way too much during cycling. The speed of the motor will be to low in my 48V scooter with a 16S but too high with a 20S

How did you get your hands on Sodium Ion??

What you're doing would be warnly welcomed by the EV and hybrid community

How on earth can a Sodium battery deliver 4V?

[roosnothanks]

BTW how do you know they're sib's and not just lib's it doesn't state on the battery does it?

1634mAh to 1475mAh - this is about 10 percent loss
of capacity after one cycle to zero volts!
9 more tests are needed to kill the battery completely! ;-)

What is brand/product number of the electronic load and power supply? Where to order sodium batteries?

[MarkusMarkus-xz]

hi! is that a self built charger with display or a finished product ? please link if it is.

how does the voltage curve compare to NMC?

It seems only the chinese are bringing this tech to the market so it makes me doubt a lot, what is the catch? why not other companies have developed such thing? All seems too good to be true, I think this might be a Li-ion battery with a diferent chemistry and maybe some Na-ion as well, some kind of hybrid.

Does it hurt to charge a sodium ion battery to 4.3 volts? I have a DIY power bank that usually takes 2 lithium batteries so it is set to turn off at 4.2 volts but I want to use 18650 sodium ion batteries that are rated at 4.0.

aww common it could be just a be fake lithium ion battery which usually has 1000mah+ unless u puncture it with nail you could never determine if its sodium ion or fake lithium ion
