MG Begins Deliveries of Liquid Solid Battery MG4 in China

SAIC’s MG has quietly crossed a significant technology milestone, with the first customer deliveries now underway in China for the MG4 Anxin Edition, a small electric hatchback that introduces liquid solid state battery technology to mass production. It is a big claim, and one that positions the MG4 as a global test case for next generation battery chemistry entering everyday cars rather than remaining locked in laboratories or concept vehicles.

The Anxin Edition sits within the broader MG4 lineup but brings meaningful hardware changes beneath the skin, offering improved efficiency, strong charging performance, and a driving range that comfortably competes with mainstream electric hatchbacks. While the model is currently China only, its underlying technology is likely to be watched closely by markets like Australia, where MG has built strong brand recognition through value focused EVs.

Liquid solid state battery is an industry first

The headline feature of the MG4 Anxin Edition is its manganese based lithium-ion liquid solid state battery, which reduces liquid electrolyte content by around five percent compared with conventional lithium batteries. While this is not a fully solid state battery, it represents a significant step toward higher energy density and improved thermal stability using technology that can already be manufactured at scale.

Key technical highlights include:

• 53.95 kWh liquid solid state battery pack
• Five percent lower liquid electrolyte content than conventional lithium batteries
• CLTC driving range of 530 kilometres
• Energy consumption rated at 11.9 kWh per 100 kilometres
• 2C DC fast charging capability
• 30 to 80 percent recharge time of 21 minutes

Power is delivered to the front wheels via a permanent magnet synchronous motor producing 120 kW and 250 Nm, which is more than adequate for an urban focused hatchback.

MG claims a 0 to 50 km per hour sprint of just three seconds, highlighting its punchy low speed acceleration rather than outright performance numbers.

Size, cabin tech and driver assistance

Dimensionally, the MG4 Anxin Edition stays consistent with the rest of the MG4 family, measuring 4,395 mm long with a 2,750 mm wheelbase, giving it proportions similar to other electric small cars sold in Australia. The slight increase in curb weight to 1,500 kg reflects the different battery chemistry, compared with lighter lithium iron phosphate variants already on sale in China.

Inside, MG has leaned heavily into digital tech and driver assistance hardware:

• 15.6 inch 2.5K central touchscreen
• Qualcomm Snapdragon 8155 infotainment processor
• Digital instrument cluster behind a flat bottom steering wheel
• Dual layer centre console for added storage
• Five cameras and twelve ultrasonic radars
• Horizon Robotics Journey J6e chip with 80 TOPS computing power
• Highway navigation assist and automated parking functions

Boot space is competitive for the segment, with 471 litres available as standard and up to 1,362 litres with the rear seats folded, making the MG4 practical beyond its city car brief.
