MG, Mercedes, Toyota, BMW & CATL Announces New Solid State Batteries With 10 Minutes Charging.

The MG4 EV’s adoption of semi-solid-state battery technology marks a significant milestone in the evolution of electric vehicles, particularly in the realm of affordability and practicality. Developed by MG Motor, a subsidiary of China’s S-A-I-C Motor, the MG4 is poised to become the world’s first mass-market electric vehicle equipped with a semi-solid-state battery. This innovation is not just a technical leap—it’s a strategic move aimed at democratizing advanced battery technology for everyday drivers.

Unlike traditional lithium-ion batteries that rely on liquid electrolytes to facilitate ion movement between electrodes, solid-state batteries replace this liquid with a solid electrolyte, offering benefits such as higher energy density, faster charging, improved safety, and better performance in extreme temperatures. However, fully solid-state batteries remain expensive and difficult to mass-produce. The MG4’s semi-solid-state battery presents a compelling compromise: it uses a gel-like electrolyte with only 5% liquid content, delivering many of the advantages of solid-state technology while remaining cost-effective. This hybrid approach enhances thermal stability and structural integrity, making the battery safer and more reliable, especially in cold climates.

The MG4’s battery, supplied by QingTao Energy, boasts an energy density of 180 Wh/kg and a capacity of 70 kWh. While this is lower than Tesla’s 4680 cells or Factorial’s advanced semi-solid-state cells, it’s a deliberate trade-off. The focus is on affordability, safety, and consistent performance rather than pushing the boundaries of range. Even so, the MG4 achieves an impressive 537 kilometers (about 333 miles) on China’s CLTC cycle, which translates to roughly 217 miles under the EPA standard. This range, combined with a competitive price tag between $11,000 and $16,500, positions the MG4 as a game-changer in the budget EV segment.

Beyond its battery, the MG4 also introduces a suite of modern features. It includes a rear-wheel-drive powertrain with 161 horsepower, a spacious and refined interior, and a smart cockpit system co-developed with Oppo. The vehicle’s design and technology reflect a mature evolution from earlier MG models, with improved comfort, connectivity, and usability. Safety has also been prioritized, with the battery passing rigorous tests including a 360-degree puncture test and demonstrating 13.8% better range retention in cold weather compared to lithium-iron-phosphate (LFP) batteries.

The MG4’s launch in China on August 5, 2025, signals a broader shift in the EV industry. It shows that advanced battery technologies are no longer confined to luxury or performance vehicles. Instead, they can be engineered for mass-market adoption, potentially reshaping global EV dynamics. While the MG4 may not be available in markets like the U.S. just yet, its debut underscores China’s leadership in battery innovation and its commitment to accelerating the transition to cleaner transportation.

The MG4 EV with its semi-solid-state battery is more than just a new car—it’s a glimpse into the future of electric mobility, where cutting-edge technology meets affordability, safety, and everyday practicality.



While SAIC Motor is the first to bring a fully functional semi-solid-state battery EV to market for mass adoption, Mercedes-Benz may soon claim an even greater milestone — becoming the first automaker to launch a vehicle powered by a true solid-state battery, and it might happen sooner than expected.
