At a media briefing, Quinbrook described its plans for eight hour batteries as a “world first”, which is not quite true because the state of NSW has already agreed underwritten contracts for five eight-hour battery projects as part of its efforts to build storage capacity to replace coal.
But that does not match the scale of what Quinbrook is doing, and Scaysbrook insists that CATL’s EnerQB technology is unlike any that has been proposed before.
“This the first battery technology to be specifically designed for an 8 hour charge and discharge,” Scaysbrook told Renew Economy.

yeah, still lithium based
from a google search
What is the CATL cell technology?
CATL's low-lithium consumption technology can greatly reduce the consumption of active lithium content during the usage of a cell and significantly improve the stability of anode material surface and structure. It is critical for satisfying the performance requirement of an ultra-long life.
I am still awainting the VRB technology to hit the market, it's ideal for large storage plants and an Aussie invention

The price of vernadium fluctuates a lot making it hard to get them off the ground atm.
