China-based Contemporary Amperex Technology Co. (CATL) has launched its new TENER energy storage product, which it describes as the world’s first mass-producible 6.25 MWh storage system, with zero …
with zero degradation in the first five years of use.
Kind of an important fact there. It's not zero degradation, but some magic new tech that makes it not degrade for a while.
Even if it’s just zero degradation in the first 5 years, that still seems like a big deal.
Totally agree. I think leaving it out of the headline made the "doubt" responses happen, though.
It's probably the same thing Tesla does, it just charges up to 80% and says that's 100%, then as it degrades it charges to a higher percent to compensate. They just give it some headroom for the degradation.
If that were true, then you probably should calculate the difference in energy density. How do they achieve that effect while increasing energy density?
That's not what they're claiming, though as someone else pointed out this article is basically a press release.
From the article:
Leveraging biomimetic solid electrolyte interphase (SEI) and self-assembled electrolyte technologies, it says that TENER enables unobstructed movement of lithium ions and achieves zero degradation for both power and capacity.
As a layman, I have no idea what this is saying, other than it's using some new thing (possibly a new material?) to achieve what the headline is claiming.
