CATL makes breakthrough on battery density

[nottyboi]

Now at 500w.kg. That is just a staggering leap Normally it doubles every 8 years but this is more the 2x in 1 year

Lithium ion and lipo already are close to 500wh/kg. Sodium and lfp are in the low 200wh/kg range. If the "breakthrough" is for sodium or lfp then it is legit, otherwise it is not worth mentioning.

Highest cell density in Teslas today is 272w /kg so you are full of crap. Sodium in production is about 160wh.

That is like saying driverless cars will never happen because Tesla can not do it. Why you use Tesla as a yardstick for anything is beyond me.

Edit: Also, the correct unit is wh/kg as it is energy density, w/kg is power density.

Tesla buys batteries from the best and most advanced Chinse battery makers, so what Tesla can and cannot do is not limited by their technology. They sell cars in China as well. The highest energy density is 250-300 wh/kg for cars in production. So if you consider that we are a year away from 500wh/kg. that is a HUGE leap.

Has it occurred to you that this breakthrough is not for cars? Do you know that the energy density of the battery in your phone, laptop, drone, ebike, etc... is significantly higher than the energy density of the batteries in an EV?

They are not higher, phones just use a higher percentage of the capacity of the cell as they don't have to last as long. EVs put a buffer range of about 10% min and 80% max to preserve battery life. If you operate in this range you get much less degradation of the cell with each cycle.
