MG launches SolidCore semi-solid-state battery in Europe that charges in record time
MG Rewrites the Rules: Semi-Solid-State Technology “SolidCore” Debuts on the Old Continent
While the giants of the automotive industry are still promising revolutions for the next decade, MG Motor (under the umbrella of the Chinese group SAIC) has decided that the future can no longer wait. The brand that managed to democratize electric vehicles in Europe is now taking the big step: introducing the first semi-solid-state batteries on the European market, under the trade name SolidCore.
This move is not just a demonstration of technological strength, but a clear strategy to dominate the "affordable EV" segment, offering performance that, until yesterday, seemed reserved exclusively for luxury models.
SolidCore Innovation: What's Under the "Hood" of Cells?
Although the term "solid-state" is often used as a magic word in marketing, MG is honest: we're talking about a semi-solid-state battery. It represents the missing link between current lithium-ion batteries (with liquid electrolyte) and fully solid-state ones, which are still extremely expensive to produce on a large scale.
How does the protective "shield" work?
The innovation from MG and SAIC (developed in partnership with QingTao) focuses on the internal structure of the cell:
- Hybrid Structure: While conventional batteries contain up to 20% liquid electrolyte, SolidCore reduces this percentage to just 5%.
- Manganese Cathode: The main innovation lies behind the separator foil. A semi-solid manganese-based cathode is applied to the aluminum foil, which is then protected by a semi-solid electrolyte “shield”.
- The anode: It remains a conventional one, using active materials such as graphite on a copper foil.
Immediate advantages for drivers:
- Extreme safety: Semi-solid structure eliminates the risk of thermal runaway. Nail penetration and extrusion tests failed to cause the cells to ignite.
- Record-breaking charging: The new battery can charge from 10% to 80% in just 21 minutes, about 25% faster than current LFP technology.
- Cold performance: Unlike liquid batteries that "suffer" in winter, the semi-solid composition is much more stable at low temperatures.
MG in Romania: The objective of 5,000 units in 2026
If at first many viewed MG with skepticism, sales figures in Romania tell a different story. The brand quickly became a top player, relying on an unbeatable quality-price ratio and the famous 7-year or 150,000 km warranty.
For 2026, MG Romania (through importer Quantum Auto Max) has set an ambitious target of 5,000 vehicles delivered, supported by aggressive price repositioning and image partnerships such as the one with the FCSB football club.
Model range and prices (2026)
The domestic market now benefits from a full range, from city hybrids to pure-blooded electric roadsters.
| Model | Powertrain Type | Special Price (Approx. incl. VAT) |
| MG3 Hybrid+ | Full Hybrid (194 HP) | from €17,797 |
| MG ZS Hybrid+ | Full Hybrid | from €20,890 |
| MG4 Electric | Electric (LFP/NMC Battery) | from €30,500 |
| MG HS Hybrid+ | Full Hybrid | from €28,990 |
| MG EHS PHEV | Plug-in Hybrid | from €33,644 |
| MG Cyberster | Electric (Roadster) | from €55,000 |
The MG4 Urban model equipped with the new SolidCore battery is expected to enter European showrooms (including Romania) towards the end of 2026, promising a WLTP range of approximately 400-450 km at an extremely competitive price.
Conclusion: Democratization of technology
MG Motor doesn't just sell cars; it sells the promise that cutting-edge technology doesn't have to cost as much as an apartment. By introducing semi-solid-state batteries on volume models like the MG4, the Chinese are putting pressure on traditional European manufacturers, who are forced to accelerate their own development cycles.
For the Romanian consumer, the news is excellent: more safety, faster charging and prices that make the switch to "electric" much more digestible.
