The MG brand, part of the Chinese group SAIC Motor, has made a move in the electrification market by announcing the mass production of its new SolidCore Battery semi-solid state batteryWith this step, the company places itself at the center of the debate on the future of electric car batteries, a key area for range, safety and usage costs.
This new technology is clearly aimed at the European customer: MG expects semi-solid batteries to be available in its electric vehicles in Europe starting in late 2026.The company speaks of a significant leap in autonomy, charging times, performance in cold climates and safety, with the aim of making its models more competitive in an increasingly demanding market.
What does the MG SolidCore semi-solid battery entail?
MG claims to have become "the world's first manufacturer" to mass-produce a semi-solid-state battery, dubbed the MG SolidCore Battery. Beyond the headline, the underlying message is that the company wants to establish its own identity in a field where many manufacturers are still in the early stages. laboratory or prototype phase.
The key to this technology lies in the use of solid-state electrolytes within each cellThese materials act as a kind of internal barrier that It strengthens safety, reduces deterioration, and extends the overall lifespan.At the same time, they allow for better battery compaction and improved performance compared to conventional lithium-ion solutions that continue to dominate the market.
According to the brand, this architecture offers Greater autonomy with the same nominal capacity, shorter recharge times, and more stable power deliveryThese are aspects that often weigh heavily in the decision to buy an electric vehicle. The promise is not only to go further on a single charge, but also to recover energy more quickly and with less degradation over the years.
One of the areas where MG places the most emphasis is performance in cold climates. The combination of solid-state electrolytes and specific electronic management allows, the company states, Start the vehicle immediately without preheating and maintain more consistent acceleration at low temperatures, a scenario in which many batteries lose efficiency and useful capacity.
The brand also emphasizes that the SolidCore Battery is designed to comply with current and future European regulations in terms of safety and performance, something that is not insignificant considering the progressive tightening of regulatory requirements associated with electrification in the European Union.
Arrival schedule to Europe and "in Europe, for Europe" approach
MG has confirmed that the SolidCore technology will be integrated into its range of European electric vehicles by the end of 2026The company has not yet detailed all the models that will debut it in Europe, but has made it clear that the development of this battery prioritizes the European market, both due to usage conditions and regulatory requirements.
In China, the brand has already begun to move in this direction: the MG4 equipped with a semi-solid battery features a 53,9 kWh package capable of homologating 530 km in the CLTC cycle, a figure which, translated to the strictest European WLTP standard, would be around 415 kmAlthough these figures come from the Asian market, they serve as a reference for what could be expected in Europe in terms of range.
Regarding recharging, MG mentions about 20 minutes to go from 30% to 80% capacity Under optimal conditions, this would place it in a competitive position against other compact electric vehicles. In the Chinese market, this variant coexists with another equipped with LFP (lithium iron phosphate) battery with similar capacity and autonomy, which leaves the door open for different chemistries to coexist in Europe as well, depending on the version and price.
All of this is part of the strategy "in Europe, for Europe"With this move, MG is trying to reinforce its connection to the European customer despite being under the SAIC umbrella. The brand insists that it's not just about bringing in products designed in China, but about adapt them to the real conditions of use in Europe: climate, road types and driving habits.
This positioning is especially relevant in a context where, for many buyers, the Chinese origin of the brand matters less than the price, autonomy and reliabilityMG is taking advantage of that gap with a range of affordable models and, now, with the added advantage of a battery technology that aims to stand out.
New Engineering Centre in Frankfurt and European development network
To support the rollout of the SolidCore Battery and other electrified technologies, MG has opened a European Engineering Centre in Frankfurt (Germany)These facilities will serve as a technical hub to adapt their vehicles to the European market and coordinate work with other centers of the brand on the continent.
The role of this center involves develop vehicles tailored to the specific conditions of EuropeFrom the differences in climate between the north and south, to the variety of road infrastructure and the different patterns of daily car use, the aim is for cars not to be simply "global" versions, but products designed with European realities in mind.
This German hub is complemented by the engineering teams in Longbridge (UK) and the MG Design Hub in Londonwhich contribute a design and product fit vision strongly influenced by the brand's British tradition. Although MG is now a Chinese-owned company, it asserts its Morris Garage roots as a defining element of its identity in Europe.
In some markets, such as Spain, MG's European network also includes support infrastructure, for example specialized spare parts and replacement centers and Martorell battery assembly plant, with the intention of facilitating the maintenance of the growing fleet and shortening after-sales waiting times.
The brand makes no secret of the fact that it is considering taking a further step with the possible Establishment of a production plant in European territoryThere is still no final decision or official location, but various reports suggest that Spain is among the options being consideredThis would be consistent with the country's weight in the automotive industry and the supply chain for electrified vehicles.
MG in the European market and the evolution of Hybrid+ technology
The launch of the SolidCore Battery comes at a time when MG is consolidating its commercial presence in EuropeThe brand claims to have already surpassed million vehicles sold on the continent Since its return, with a range that includes models such as the MG ZS, HS and MG3, very present in volume segments and with electrified versions.
So far this year, MG is positioned as China's leading manufacturer by sales volume in Europe, including the UKIn the first two months, more than 41.000 unitsThis represents an increase of nearly five percent compared to the same period last year. While not overwhelming in the context of the overall market, these figures reflect sustained growth.
In parallel with the development of semi-solid batteries, the company continues to evolve its Hybrid+ technologyMG highlights that in 2025 it sold around 137.000 hybrid vehicles, which represents strong growth compared to the previous year and places the The MG HS is among the most popular plug-in hybrids in numerous European countries, including Spain..
The latest iteration of Hybrid+ incorporates a higher capacity battery, around 1,83 kWhThis allows for an expansion of pure electric driving mode on urban journeys, and thus, reduce consumption and usage costs. To this is added a three-speed hybrid transmission, an unusual solution in the segment that seeks to optimize the available torque and the overall response.
The system is based on a hybrid control unit (HCU) with real-time terrain sensingIt is capable of managing up to eight different operating modes. In this way, the vehicle can automatically adapt power delivery and the distribution between the combustion engine and the electric motor according to the gradient, road type, or driving style, in an attempt to improve both efficiency and driving pleasure.
Performance, safety and user experience with the SolidCore Battery
Beyond capacity and autonomy figures, MG insists that the big leap forward for the SolidCore Battery lies in the combination of consistent performance, enhanced safety and reliability across a wide temperature rangeThe semi-solid architecture reduces the risk of thermal instabilities associated with certain liquid electrolytes, something especially sensitive in high energy density batteries.
The solid-state electrolytes that form the internal structure of each cell They act as a physical barrier that helps contain possible unwanted reactions. avoid accelerated degradationAccording to the brand, this approach not only extends battery life but also maintains a high level of safety even when the battery is subjected to intensive use, frequent fast charging, or extreme climates.
In everyday use, the promise of immediate start-up without preheating and of Improved acceleration in cold weather This could be especially interesting for drivers in northern Europe or mountainous areas, where many electric vehicles currently lose some of their range and responsiveness when the temperature drops.
The company links this development to its overall strategy of making the make electric mobility more accessible and easier to useLess time plugged into the charger, less capacity loss over time, and more predictable winter usage are arguments that MG wants to put on the table to convince those who are still undecided between an electric vehicle and other technologies.
Company officials, such as Kimi Li, Vice President of MG in Europe and the United KingdomThey maintain that both the SolidCore Battery and the evolution of Hybrid+ have been designed with a practical, oriented approach to to provide tangible benefits to the user and to position their models competitively within their categorypreventing technology from becoming just a marketing ploy.
With the combination of mass production of semi-solid-state batteries, the strengthening of its engineering network on the continent, and the deployment of improved hybrid solutions, MG seeks to consolidate its position as one of the most active players in the electrification of the European market, targeting both those who have already made the leap to pure electric vehicles and those who prefer an intermediate point with hybrid technologies.
