First real solid-state battery EV range tests cover 650 miles on a charge with a 150 kWh pack

[Redaktion]

The 150 kWh battery pack with 95% solid electrolyte of the refreshed NIO ET7 was able to propel it to more than 600 miles on a charge in three separate test scenarios.

The title is disingenuous in relation to the content.

360Wh/Kg is less than you'd expect from a real solid-state battery; regular batteries with a higher proportion of silicon could already reach this gravimetric energy density

Where did you get the 0.36 kWh/Kg spec? It's not listed.
In any case, 0.36 kWh/Kg is better compared to today's Li-Ion batteries. In 2026, we should expect 0.40 kWh/Kg solid-state batteries, and in 2027 0.50 kWh/Kg is to be expected, according to Toyota.
However, the full-potential of solid-state batteries is 1.00 kWh/Kg. Looking forward for that!

I could not find any into on life expectancy for this semi-solid state battery. Many articles that NIO and CATL are developing other batteries to address short battery life span but no specific info on what could be expected from this one.
Besides manufacturing life expectancy is the biggest hurdle for solid state batteries. And likely the reason we don't see them in smartphones and other small devices.
