GAC GROUP

China has completed its first large-capacity all-solid-state battery production line, according to Chinese state media. The facility, built by GAC Group, is currently producing 60 Ah+ vehicle-grade cells on a small-batch test basis. These cells are projected to allow electric vehicles with current 500 km ranges to exceed 1,000 km once integrated. Mass production is planned for 2027-2030.

The term “60 Ah+” refers to the capacity of each battery cell in ampere-hours (Ah). A 60 Ah cell can theoretically supply 60 amperes for 1 hour before discharging completely. Higher Ah per cell generally means more energy

storage, which can translate into a longer driving range when multiple cells are assembled into a battery pack.

All-solid-state batteries use solid electrolytes instead of liquid ones, which improves thermal stability and safety. GAC’s production line reportedly achieves an areal capacity of up to 7.7 mAh/cm², compared with less than five mAh/cm² in traditional “wet” lithium-ion manufacturing.

GAC’s research director, Qi Hongzhong, said the energy density of the new solid-state cells is nearly double that of conventional batteries. Vehicles currently capable of 500 km (~310 miles) on a single charge could potentially reach more than 1,000 km (~620 miles) with these cells.

The company is using a “dry” anode production process that combines slurry mixing, coating, and rolling into a single step. This technique reportedly improves manufacturing efficiency and reduces energy consumption. The solid electrolyte can tolerate higher temperatures than liquid electrolytes, reportedly withstanding 300–400 °C compared with approximately 200 °C for conventional batteries.

Small-batch vehicle integration tests are planned for 2026, with a gradual ramp-up to mass production between 2027 and 2030. While the milestone represents a significant technical achievement, commercialisation will depend on investment, reliable supply of solid electrolyte materials, and validation of long-term performance and safety in vehicles.

SAIC Motor

SAIC Motor said its partner Qingtao Power’s all-solid-state battery production line in Anting has achieved full-line commissioning, and the firm expects sample cells to roll off the line by the end of this year, with prototype vehicles to undergo testing next year and commercial mass-delivery scheduled for 2027, as reported by IT-home.

SAIC has previously described technical targets for the new solid-state chemistry: a gravimetric energy density above 400 Wh/kg, a volumetric energy density above 820 Wh/L, and single-cell capacities greater than 75 Ah. Those figures were disclosed in earlier corporate communications and press briefings and have been repeated in trade outlets and SAIC’s technology summaries.

The company also provided safety performance data for the chemistry, reporting that cells passed nail-penetration tests and sustained exposure in a 200°C thermal chamber without catching fire or exploding, and that low-temperature capacity retention exceeds 90 per cent. SAIC’s published materials present these results as laboratory and validation data linked to its stated development roadmap.

SAIC’s engagement with solid-state development dates back several years and includes collaborative investment with Qingtao Energy; reporting indicates SAIC has invested in the partner and that a joint laboratory was formed to accelerate development. Industry outlets cite those earlier steps as part of a multi-year program to scale the technology from laboratory samples to vehicle use.

Analysts warn that sample-line commissioning and controlled safety tests are milestones but not proof of long-term manufacturability, cost efficiency or field reliability. Commercial success will depend on repeatable mass-production yields, supply-chain readiness and real-world durability data gathered through fleet testing. No pricing or commercialization terms were announced in the interaction; currency conversions are not applicable.

By comparison, SAIC is not alone in pursuing the commercialization of all-solid-state batteries

. GAC Group recently built China’s first large-capacity (60 Ah+) solid-state battery production line, with small-batch cells already rolling and mass production pencilled in for 2027-2030. Chery – another Chinese automaker – has unveiled a 600 Wh/kg solid-state battery module and is targeting pilot-vehicle use in 2026 and a broader rollout in 2027. Meanwhile, battery maker Sunwoda (backed by Li Auto) is developing a 400 Wh/kg cell with a 1,000 km projected range and 1,200-cycle lifespan. On the other hand, CATL has pushed back on some of the more ambitious rumours, saying mass-scale solid-state production is not expected until around 2030, despite continued R&D investment.

MG4 Anxin Edition, first mass-produced car with a semi-solid-state battery, debuts at Guangzhou Auto Show

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.

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.

Interior features a 15.6-inch central touchscreen, column-mounted shifter, and 50W wireless charging pad.

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.
