SAIC’s MG brand will introduce the MG4 Anxin Edition at the Guangzhou Auto Show on November 21, positioning it as one of the first mass-production passenger cars equipped with a semi-solid-state battery. The model utilises a manganese-based lithium-ion battery pack jointly developed by SAIC and QingTao Energy, which is rated for 530 kilometres on the CLTC cycle. The current MG4 range is priced from 68,800 to 102,800 yuan (9,690 to 14,490 USD).
The MG4 Anxin Edition has not yet been unveiled in its final production form, but regulatory filings suggest that its exterior design aligns with the existing MG4 lineup. The car retains the wide-body hatchback profile, the Cyberster-inspired front fascia, and the illuminated MG badge.
Dimensions remain unchanged at 4,395 mm in length, 1,842 mm in width, and 1,551 mm in height, with a wheelbase of 2,750 mm. The rear continues to feature a full-width light bar with arrow-style position lights.
Inside, the model uses the updated MG4 interior design. The central screen grows from 12.3 inches to 15.6 inches, mechanical buttons beneath the display are removed, and the rotary shift controller is replaced with a column-mounted selector. A 50-watt wireless charging pad is added to the lower console. The car also features the MG–Oppo intelligent cockpit system, powered by a Snapdragon 8155 chip.
The battery capacity remains at 53.95 kWh, identical to the 530-km LFP variant. However, the semi-solid-state pack increases the curb weight to 1,500 kg, approximately 15 kilograms more than the standard model. The single front motor provides 120 kW and 250 Nm, with a claimed 0–50 km/h acceleration time of 3 seconds. MG reports October MG4 sales of 11,480 units, with the Anxin Edition set to join the lineup as an additional option once production commences.
Semi-solid-state batteries combine solid and liquid electrolyte components, with solid materials typically accounting for more than 90 per cent of the total electrolyte structure. This configuration enables higher energy density and improved thermal stability compared to conventional liquid-electrolyte lithium-ion cells, while remaining compatible with existing production lines.
As China moves toward standardising technical nomenclature in this field, regulators are preparing to rename semi-solid-state batteries as “solid-liquid batteries” to distinguish them from fully solid-state systems currently under development.
