MG4 Becomes First EV with Semi-Solid-State Battery Approved for Sale in China

A Breakthrough in EV Battery Technology

The MG4 has officially become the first mass-produced electric vehicle to be approved for sale with a semi-solid-state battery. China’s Ministry of Industry and Information Technology (MIIT) included the model in its latest sales clearance list, marking a key step toward broader adoption of the technology.

Launch Timeline and Pricing

SAIC Motor opened pre-orders for the updated MG4 earlier this month starting at 73,800 yuan ($10,000). Pricing for the semi-solid-state version will be announced in September, with deliveries expected by the end of 2025.

Battery and Performance

The new variant keeps the same 120 kW (161 hp) single front-mounted motor as other MG4 models but replaces the lithium iron phosphate (LFP) battery with a manganese-based lithium-ion pack. This advanced battery is made by Suzhou Qingtao Power Technology, a leader in solid-state EV battery production.

Features and Options

Buyers can choose from four trims—Comfort, Ease, Freedom, and Smart—with existing battery pack options of 42.8 kWh (437 km / 272 miles CLTC range) and 53.9 kWh (530 km / 330 miles CLTC range). Optional features include:

• 360-degree camera

• Front and rear parking radars

• Distinctive front badging

• Tinted roof and privacy glass

Design and Interior

The MG4 measures 4,395 mm long, 1,842 mm wide, and 1,551 mm tall, with a 2,750 mm wheelbase—slightly larger than the BYD Dolphin. Inside, it is expected to feature the 15.6-inch floating infotainment display and smart tech found in other MG4 models.

Global First

SAIC MG says the semi-solid-state MG4 will be the first mass-produced EV of its kind to launch globally. Full specifications, including range and capacity, will be revealed in September.
