Breakthrough in EV Technology: First Mass-Produced Semi-Solid-State Battery EV Approved for Sale







The electric vehicle landscape is undergoing a significant transformation with the impending release of the first mass-produced EV featuring a semi-solid-state battery. This groundbreaking advancement is spearheaded by the new MG4, which has recently secured clearance for sale in the Chinese market. This milestone brings the industry closer to achieving what many refer to as the ultimate battery solution for electric cars, promising enhanced efficiency and performance. The variant of the MG4 equipped with this innovative power source was formally listed among approved vehicles by China's Ministry of Industry and Information Technology, signifying its readiness for consumer availability.
The MG4 with its new battery system represents a notable departure from previous models. While retaining the familiar 120 kW (161 hp) front-mounted electric motor, the primary innovation lies beneath the hood: a manganese-based lithium-ion battery. This advanced battery, produced by Suzhou Qingtao Power Technology Co., a recognized leader in solid-state Li-ion batteries for EVs, replaces the lithium iron phosphate (LFP) batteries found in other MG4 versions. Although detailed specifications regarding range, battery capacity, and final pricing for this particular model are yet to be disclosed, pre-orders for the standard MG4 models commenced earlier this month, with prices beginning around $10,000 (73,800 yuan). The official pricing for the semi-solid-state battery variant is anticipated in September, with deliveries projected to start by the close of 2025.
Beyond its pioneering battery technology, the new MG4 boasts a contemporary design and a suite of features. Measuring 4,395 mm in length, 1,842 mm in width, and 1,551 mm in height, with a 2,750 mm wheelbase, it presents a slightly larger profile than competitors like the BYD Dolphin EV hatch. Inside, the semi-solid-state battery model is expected to feature a modern interior, including a 15.6-inch floating infotainment system and an array of smart technologies. Standard MG4 trims, including Comfort, Ease, Freedom, and Smart, are offered with battery options of 42.8 kWh and 53.9 kWh, providing CLTC ranges of 437 km (272 miles) and 530 km (330 miles) respectively, with prices ranging up to 105,800 yuan ($15,000) for the premium Smart edition. This vehicle is poised to be a global pioneer, making advanced battery technology accessible to a broader market and propelling the electric vehicle sector into a new era of possibilities.
The arrival of this new electric vehicle, integrating cutting-edge battery technology, underscores humanity's relentless pursuit of progress and sustainability. It exemplifies how dedication to innovation can overcome complex challenges, leading to solutions that benefit both consumers and the environment. This development encourages us to embrace future possibilities with optimism, highlighting the positive impact that collaborative research and technological advancement can have on shaping a more efficient and cleaner world.
