MG, the electric vehicle brand under SAIC Motor, has officially started deliveries of the MG4 Anxin Edition in China, marking the world’s first mass-produced EV equipped with a semi-solid-state battery. This milestone signals a major advancement in commercial EV battery technology, bridging the gap between traditional lithium-ion and future solid-state batteries.
The semi-solid-state battery promises enhanced safety, thermal stability, and performance, while remaining cost-effective for mass-market adoption.
Advanced Semi-Solid-State Battery Details
The MG4 Anxin Edition is powered by a 53.95 kWh manganese-based semi-solid-state battery co-developed with QingTao Energy. Key advantages of this battery technology include:
-
Reduced liquid electrolyte, improving thermal stability and structural integrity.
-
Enhanced safety and reliability compared to conventional lithium-ion batteries.
-
Improved cold-weather performance and rigorous compliance with national safety standards.
Performance and Charging Capabilities
The new MG4 model offers competitive performance for mainstream EV buyers:
-
CLTC-rated driving range of up to 537 km per charge.
-
140 kW DC fast-charging, delivering approximately 400 km of range in just 12 minutes.
-
Intelligent battery management systems to maintain high efficiency and longevity.
Market Positioning and Pricing
The MG4 Semi-Solid-State Anxin Edition targets the mainstream family EV segment, with a launch price of RMB 102,800 (~$14,400), and limited-time subsidies bringing the price closer to RMB 99,800 (~$14,000) in China.
It combines next-generation battery technology with modern EV features, including driver-assist systems, smart connectivity, and thermal management, offering a practical and safe solution for everyday use.
Significance for the EV Industry
Deliveries of the MG4 Anxin Edition mark a pivotal moment in battery innovation, demonstrating that semi-solid-state chemistry can be implemented at scale. This technology offers a safer, higher-performing alternative to traditional lithium-ion batteries without the high costs associated with full solid-state cells.
Industry analysts view this as a game-changing step for EV adoption, indicating that advanced battery technologies are moving from concept to mainstream production.
Outlook
With mass production now underway in China, the MG4 Anxin Edition sets a new benchmark for EV battery technology, paving the way for broader adoption of semi-solid-state batteries in other vehicle segments and international markets.
