MG4 Anxin Edition: First Mass-Produced EV with a Semi-Solid-State Battery Cleared for Sale

A new chapter in electric vehicle history has begun. SAIC Motor’s MG4 Anxin Edition has become the first mass-produced EV to be officially cleared for sale with a semi-solid-state battery. The approval comes from China’s Ministry of Industry and Information Technology (MIIT), and it marks the first time this next-generation battery technology will reach the consumer market on a large scale.

Pre-orders for the MG4 opened earlier this month, with the standard lithium iron phosphate (LFP) variants starting at 73,800 yuan (around USD $10,000). Now, with the semi-solid-state version confirmed, excitement is building ahead of its official September 2025 launch, when SAIC will announce full specifications, range details, and final pricing.

Summary Table

What Is a Semi-Solid-State Battery?

Semi-solid-state batteries represent a middle ground between conventional lithium-ion and full solid-state designs. In this technology, most of the liquid electrolyte is replaced with a gel-like or semi-solid material  typically less than 10% of the battery content. This brings several key advantages:

• Improved Safety: Reduced risk of thermal runaway and better puncture resistance

• Enhanced Cold-Weather Performance: More consistent energy delivery in low temperatures

• Higher Energy Density: Potential for longer range within the same size battery pack

• Greater Structural Stability: Less risk of expansion or leakage over time

In the MG4 Anxin Edition, the liquid electrolyte content is around 5%, a key factor that qualifies it as a semi-solid-state battery. SAIC reports that in testing, the pack retained 13.8% more range at -7°C compared to a traditional LFP battery.

Battery Supplier and Technology

The MG4’s semi-solid-state battery is supplied by Suzhou QingTao Power Technology Co., a leader in advanced lithium battery manufacturing. This manganese-based lithium-ion battery design blends the improved performance characteristics of solid-state chemistry with the scalability of current lithium-ion production lines.

While SAIC has not yet disclosed the exact capacity for the Anxin Edition, industry sources estimate a 70 kWh pack. Based on internal testing, the model is expected to deliver a CLTC-rated range of about 537 km on a single charge.

MG4 Anxin Edition: Dimensions and Performance

Despite the battery change, the MG4 Anxin Edition maintains the same drivetrain as its LFP siblings:

• Motor: Front-mounted electric motor producing 120 kW (161 hp)

• Length: 4,395 mm

• Width: 1,842 mm

• Height: 1,551 mm

• Wheelbase: 2,750 mm

These dimensions put the MG4 slightly larger than the popular BYD Dolphin hatchback, offering more cabin space while remaining compact enough for city driving.

Trim Levels and Features

The MG4 will be available in four trims: Comfort, Ease, Freedom, and Smart. While all trims benefit from MG’s latest infotainment and safety technology, buyers can opt for several extras on the Anxin Edition:

• 360-degree camera system

• Front and rear parking radars

• Optional tinted panoramic roof

• Privacy glass

• Exclusive front badging

Inside, the MG4 will feature the brand’s modern 15.6-inch floating infotainment display, advanced driver assistance features, and a clean, minimal interior design.

Pricing and Launch Timeline

Standard MG4 models with LFP batteries are priced from 73,800 yuan (~USD $10,000), but SAIC has yet to reveal the Anxin Edition’s price. Given the advanced technology, industry analysts expect a premium over existing trims, though SAIC is aiming to keep it competitive.

Key Dates:

• August 2025: Pre-orders for MG4 range opened

• September 2025: Official pricing and specifications for Anxin Edition revealed

• Late 2025: First customer deliveries expected

Is It Really the First?

Yes  the MG4 Anxin Edition is considered the first mass-produced EV with a semi-solid-state battery to receive regulatory clearance for public sale. While some earlier prototypes and limited-edition models, such as the IM L6, experimented with semi-solid batteries, none have reached full production at scale.

Frequently Asked Questions

Q1: What makes the MG4 Anxin Edition’s battery different from standard EV batteries?

A. It uses semi-solid-state technology, replacing most liquid electrolyte with a gel-like substance. This improves safety, performance, and cold-weather range.

Q2: Is this the first time semi-solid batteries have been used in a car?

A. No  but it is the first time they have been used in a mass-produced and officially approved consumer EV.

Q3: Will the semi-solid-state MG4 be more expensive?

A. Likely yes, though SAIC aims to keep the price within reach of mainstream EV buyers. Exact pricing will be revealed in September 2025.

Q4: When can customers take delivery?

A. Deliveries are planned to begin before the end of 2025.

Q5: Who makes the battery?

A. Suzhou QingTao Power Technology Co., a Chinese company specializing in semi-solid and solid-state battery development.
