MG Motor announced that it has begun deliveries of its all-new MG4 Anxin Edition in China, touted as the world’s first mass-produced passenger vehicle equipped with a semi-solid state battery pack.
The all-new MG4 first made its debut back in September 2025 with five variants available at launch. The new Anxin Edition is priced at RMB102,800 (approx. RM60k), making it the most expensive variant in the line-up.
Specifications for the semi-solid state battery pack are centred on a 53.95 kWh unit. It comprises a manganese-based lithium-ion liquid-solid chemistry that has only 5% liquid electrolyte content within the battery pack. MG says that semi-solid-state batteries deliver better low-temperature performance and enhanced structural integrity compared to a normal LFP battery.
This battery powers a front-mounted electric motor making 163 hp (120 kW) and 250 Nm, which enables a range of 530 km (CLTC), with a claimed power efficiency of 11.9 kWh/100 km. For comparison, this is the same range managed by the non-semi-solid state battery variant, which is equipped with a standard 53.95 kWh LFP battery pack.
MG states the MG4 Anxin Edition can be recharged from 30-80% in 21 minutes under 2C fast charging. This equates to approximately 108 kW DC fast charging.
Despite semi-solid-state batteries being technically more energy dense, the Anxin Edition is actually heavier than its standard siblings. CarNewsChina reports a kerb weight of 1,500 kg, which is a slight increase over the LFP-equipped variants that weigh in at 1,415 kg and 1,485 kg.
In the realm of physics, a heavier EV requires more energy to get moving due to inertia, typically resulting in a shorter range. However, despite the added weight, the range on the Anxin Edition remains the same as the LFP-equipped variants.
As the name “Anxin” – which translates to peace of mind in English – implies, MG is likely prioritising thermal safety and cold-weather performance on here, over the power-to-weight gains usually associated with the technology.
According to MG Motor, the semi-solid-state battery has reportedly passed a series of tests, including a direct 1000°C fire for 180 seconds and a 10mm needle puncture test. MG claims that in both instances, the battery did not produce any smoke, fire, or explosion, even after two hours of testing.
Additionally, the manganese-based lithium-ion liquid-solid chemistry allows for stable discharging at temperatures as low as -30°C and maintains high-efficiency charging even at -25°C.
