The global electric vehicle (EV) market has been thrown into the spotlight following a bold announcement from Chinese automaker SAIC Motor. At the 2025 Chengdu Auto Show, SAIC’s MG brand revealed the MG4 Anxin, the world’s first mass-produced EV equipped with a semi-solid-state battery. Priced at around $14,000, the vehicle blends affordability, safety, range efficiency, and next-generation charging capabilities.
This launch is more than just a new model release it represents a significant leap in EV battery technology and a direct challenge to established Western automakers who have been slower to innovate in this area.
What is the MG4 Anxin?
The MG4 Anxin is part of the MG4 family of hatchbacks and represents a major upgrade due to its semi-solid-state battery technology. It retains the compact yet practical design of the MG4 series but integrates advanced battery chemistry that offers a better balance of safety, performance, and cost.
Key Highlights
-
Semi-solid-state battery: Uses a gel-like electrolyte with a small liquid content for stability.
-
Improved energy density: Around 180 Wh/kg, higher than standard lithium iron phosphate (LFP) packs.
-
Cold-weather efficiency: Maintains nearly 14% more range in freezing conditions compared to LFP versions.
-
Affordable entry price: Around $14,000 after introductory discounts.

Semi-Solid-State Battery: A Technological Breakthrough
While full solid-state batteries are still years away from mass production, semi-solid-state batteries act as a transitional technology. They combine the advantages of conventional lithium-ion cells with enhanced safety and higher energy density.
Benefits Over Traditional Batteries
-
Safety: Reduced fire risk due to gel-based electrolyte.
-
Range: Slightly higher driving range compared to LFP alternatives.
-
Durability: Improved charging longevity and resilience in extreme climates.
This makes the MG4 Anxin the first commercially available EV to demonstrate how semi-solid-state technology can be scaled for mass-market vehicles.
