MG Motor has started deliveries of its new MG4 Anxin Edition hatchback, marking a significant milestone as the first mass-produced electric vehicle equipped with semi-solid-state battery technology. The announcement comes as MG’s parent company, SAIC Motor, pushes advanced battery tech into mainstream EV markets, aiming to balance performance, safety and affordability.
The MG4 Anxin Edition officially began rolling out to customers in China this week after debuting at major auto shows earlier this year. The car is built on MG’s popular compact EV platform and represents the first production application of a manganese-based semi-solid-state lithium-ion battery developed in partnership with QingTao Energy.
The semi-solid battery has a 53.95 kWh capacity and retains a similar driving range to traditional lithium iron phosphate (LFP) packs, offering about 530 kilometres on the CLTC cycle. Despite the advanced chemistry, the battery contains roughly 5 % liquid electrolyte, making it a hybrid between traditional and full solid-state designs.
Powered by a 120 kW (163 hp) front-mounted motor with 250 Nm of torque, the MG4 delivers standard EV performance with a smooth, efficient driving profile. The semi-solid-state battery also supports fast charging, reaching from 30 % to 80 % charge in around 21 minutes under 2C charging conditions.
Manufacturers say this battery type offers improved safety and better low-temperature performance compared to traditional liquid electrolyte cells, a key focus for broader EV adoption in varied climates. MG claims the semi-solid technology enhances structural stability and thermal management without significantly increasing cost.
Despite the added tech, the Anxin Edition weighs slightly more than standard MG4 models and maintains a price point aimed at mainstream buyers. Starting prices hover in the 100,000-yuan range (about $14,600), bringing advanced EV battery technology within reach of more consumers and signalling a new phase in electrified mobility.
