The MG4 Anxin Edition just became the world's first mass-produced passenger car with a semi-solid-state battery. Deliveries began in China on December 18, 2025, priced at 102,800 yuan ($14,600). That makes it not just a technology milestone, but a remarkably affordable one.
The battery uses a manganese-based lithium-ion chemistry with what MG describes as "5% less liquid electrolyte content than conventional lithium batteries." That phrasing is important: this is a liquid-solid hybrid, not a fully solid-state cell. The distinction matters because it tells you where the industry actually is versus where the press releases want you to think it is. Still, the pack delivers 53.95 kWh, supports 2C fast charging (30% to 80% in 21 minutes), and provides 530 km of CLTC range.
🔋 The Specs Behind the Hype
The front-mounted permanent magnet synchronous motor produces 120 kW (161 hp) and 250 Nm. Top speed is 160 km/h, with a 0-50 km/h time of 3 seconds. Curb weight lands at 1,500 kg, which is 15-85 kg heavier than the standard MG4 trims running conventional LFP cells (1,415-1,485 kg). The extra weight comes from the denser battery chemistry, but MG compensates with a claimed 11.9 kWh per 100 km consumption figure.
Dimensions are identical to the regular MG4: 4,395 mm long, 1,842 mm wide, 1,551 mm tall, on a 2,750 mm wheelbase. Cargo capacity is 471 liters standard, expanding to 1,362 liters with the rear seats folded. Body torsional rigidity hits 31,000 Nm/deg, which is competitive for the segment.
Inside, MG fitted a 15.6-inch 2.5K central display running on a Qualcomm Snapdragon 8155 chip. The ADAS suite includes five cameras and 12 ultrasonic radars, processed by a Horizon Robotics Journey J6e chip rated at 80 TOPS.
What It Means for Solid-State
The Anxin Edition is a proof of concept more than a paradigm shift. A 5% reduction in liquid electrolyte content won't transform safety profiles or energy density in any dramatic way. But it puts semi-solid-state chemistry into a production vehicle at a price point that undercuts most conventional EVs in Western markets. The technology works, it scales, and it costs $14,600. That's the real story here.
China's solid-state battery industry is moving in parallel on multiple fronts. CATL and BYD are targeting full solid-state integration by 2027. The Chinese government released its first national standard for solid-state batteries just two weeks after the MG4 Anxin started deliveries. The MG4 isn't the endgame for this technology. It's the first car off the starting line.
