SAIC rolls out semi-solid-state batteries across vehicle range

The Chinese automaker SAIC, confirmed on 3 April 2026 that it will equip production models from multiple brands with semi-solid-state packs this year while holding its target for full solid-state cells at 2027. The move points to how quickly battery chemistry is advancing from laboratory promise to factory reality and what it means for cost control, safety protocols and range competitiveness in volume EV manufacturing.

SAIC Motor Corporation told investors via the Shanghai Stock Exchange platform on 3 April 2026 that it would progressively introduce semi-solid-state batteries across its various marques during the current year. Full solid-state production remains scheduled for 2027. The announcement sat alongside group targets of five million vehicles wholesaled and revenue above 700 billion CNY ($101.7 billion) for 2026.

SAIC's semi-solid-state battery strategy

The group is no stranger to the technology. Its global passenger-car brand MG, has already delivered the world's first mass-produced semi-solid-state pack. The MG4 Anxin Edition was delivered to customer hands in China on 18 December 2025. Its 53.95 kWh manganese-based unit contains only five per cent liquid electrolyte against roughly 20 per cent in standard cells. That slimmed-down chemistry yields a CLTC (China Light-Duty Vehicle Test Cycle) range of 530 km and allows DC fast-charging from 30 per cent to 80 per cent in about 20 minutes.

On 10 March 2026 SAIC unveiled the MG 4X compact crossover which will use the identical battery across all variants with production ramp-up set for the end of the second quarter. Premium sub-brand IM Motors fielded an earlier version in the 2024 IM L6 sedan delivering a 130 kWh pack and a claimed 1 000 km CLTC range.

This latest, April statement now extends the chemistry across the wider group on a brand-by-brand schedule.

The technical backbone is a polymer-inorganic composite electrolyte developed with Shanghai start-up QingTao Energy Development in which SAIC holds a significant stake. The same partner runs the Anting production line that completed full-process commissioning in late 2025.

Safety and manufacturing advantages

For plant engineers, the lower liquid content brings immediate operational gains, as SAIC reports that the cells have passed nail-penetration and 200 °C thermal-box tests without ignition or explosion. This reduced thermal-runaway risk simplifies pack architecture, trims cooling-system demands and eases factory fire-suppression requirements. It also paves the way for lighter structural battery integration without relaxing production-line safety standards.

With automotive production still mindful of occasional high-profile incidents, the proven abuse tolerance translates directly into more flexible line layouts, ad well as smoother regulatory approval and lower insurance costs.

China's Geely redraws global engineering map with Geely Tech Europe

By merging its Gothenburg and Frankfurt engineering centres into Geely Technology Europe, the Chinese auto giant is making a calculated wager that embedding European expertise from day one will sharpen its vehicles for every market on the planet.

Rivals race to catch up

Scaling will decide whether the advantage holds. China's solid-state battery shipments reached 5.9 GWh in 2025 and are forecast to hit 11.9 GWh by 2027. Yet China’s domestic competitors are moving fast.

GAC has commissioned a large-capacity solid-state line with volume output targeted between 2027 and 2030, while Chery has demonstrated a 600 Wh/kg module aimed at pilot vehicles in 2027. Market leader CATL, meanwhile, expects true solid-state mass production no earlier than 2030.

SAIC's two-year window for semi-solid rollout followed by full solid-state consequently represents an aggressive timetable that hinges on QingTao's ability to industrialise faster than the pack.

Broader industry implications

Although these production moves are unfolding in China, the implications reach far beyond Shanghai. Western and Korean cell makers have poured capital into liquid-electrolyte gigafactories yet remain years behind on solid-state roadmaps. In other words, should SAIC deliver the promised performance at volume and acceptable cost, it will compress global pricing curves and force faster licensing or joint-venture activity among European and North American OEMs already wrestling with high capital expenditure and slower EV uptake.

At the same time, the heavy concentration of know-how among a handful of Chinese suppliers sharpens strategic-dependence questions for any manufacturer pursuing localisation under tightening rules of origin.

SAIC has chosen the pragmatic middle path. The carmaker is commercialising the intermediate semi-solid chemistry today while the full solid-state line is still under construction. That approach shortens the traditional decade-long development cycle and turns battery chemistry into a genuine manufacturing differentiator rather than a supplier-controlled black box. For plant managers and procurement teams, the signal is clear. The next phase of EV competitiveness will hinge less on who assembles the most vehicles and more on who masters the chemistry inside the pack.

Whether SAIC can convert laboratory metrics into reliable high-volume output at competitive prices will determine if this leap sets an industry benchmark or remains an impressive pilot. For the moment, the group has planted a very public marker. The rest of the automotive manufacturing world will watch the production data with close attention.
