Elektrofahrzeug mit Semi-Solid-State-Akku mit 1000 km, 620 Meilen Reichweite und Schnellladung auf 40 % in 12 Minuten. (Hohe Energiedichte von Festkörperbatterien von 500 Wh/kg, geeignet für die Luftfahrt.)

MG’s parent company is about to release an electric sedan in China. Regulatory approval documents claim it will have a 123 kWh semi-solid state battery pack, and 1002 km (620 mile) range on a single charge when measured on the CLTC cycle. Expected Australian price $A74,400. Fast charging for 12 minutes to add 400 km of range. The semi-solid-state battery pack was developed by Qungtao Energy.

Other recent solid-state battery developments: [Solid state batteries from Samsung featured at the battery expo in Seoul](https://www.notebookcheck.net/Samsung-delivers-solid-state-battery-for-EVs-with-600-mile-range-as-it-teases-9-minute-charging-and-20-year-lifespan-tech.867768.0.html) with a claimed energy density of 500 Wh/kg, approximately double the density of mainstream EV batteries. [According to CATL this energy density makes them suitable for aviation purposes](https://batteryindustry.net/catl-a-new-battery-will-enable-an-8-tonne-electric-plane-to-travel-1800-miles/) by allowing longer range flights.

Notably, though, the Chinese MPG/range testing cycle is very lenient. A more realistic estimate for range would probably look like a kilometers-to-miles conversion by comparison!
