SAIC Motor will begin selling the MG 4X electric SUV equipped with a semi-solid-state battery in less than a week [1].
The launch represents a significant shift in battery chemistry for the consumer market. By moving toward semi-solid-state technology, the company aims to improve the efficiency and performance of electric vehicles compared to traditional liquid-electrolyte batteries.
The MG 4X is slated for release in Europe and other global markets [2]. This follows a previous milestone for the brand, which launched the first mass-produced electric vehicle utilizing semi-solid-state battery technology in 2025 [1].
The company is positioning this release as a strategic move to lead the next generation of EV power. The transition from traditional lithium-ion setups to semi-solid-state cells is intended to provide a more stable and dense energy source, a goal that has long been a hurdle for the automotive industry.
"We are setting a new benchmark," an MG spokesperson said [2].
The vehicle is expected to be available for purchase by mid-May 2026, based on the timeline provided on May 7 [1]. The rollout in Europe serves as the primary launch market before the SUV becomes available in other regions [2].
“"We are setting a new benchmark."”
The introduction of the MG 4X signals a transition from experimental to commercial application for semi-solid-state batteries. While fully solid-state batteries remain a long-term goal for the industry, semi-solid versions provide a bridge that potentially increases energy density and safety without requiring a complete overhaul of current manufacturing processes.
