Some additional keywords on the tech behind this extended range capability:

… self-generated anode battery technology (which no longer uses traditional graphite anode material but allows elements to deposit on the current collector in metallic form, increasing volumetric energy density by 60% and gravimetric energy density by 50%)

…

Additionally, CATL’s self-generated anode technology can be adapted to multiple material systems. For example, when paired with sodium-ion systems, the energy density can reach 350Wh/L; with phosphate systems, it can reach 680-780Wh/L; and with ternary systems, it can exceed 1000Wh/L.

The source cites CATL, but this self-generating anode tech has apparently been studied for a while by more than CATL.
