One Reason to Be Excited for the Next-Gen MG4: Semi Solid-State Batteries
The MG4, MG’s all-electric hatchback, has been making quiet inroads globally but hasn’t exactly set sales charts alight here or in its home market of China. While it offers competitive pricing and decent driving dynamics, it faces stiff competition from domestic EV giants such as BYD and Geely. That could change with the next-generation MG4, which will introduce something enthusiasts and EV advocates have been talking about for years — semi solid-state batteries.
According to Car News China, Chinese regulatory filings have revealed the MG4 Anxin Edition, which swaps the lithium iron phosphate (LFP) battery used in some current models for a manganese-based lithium-ion semi solid-state battery. The cells will be supplied by Suzhou QingTao Power Technology Co., Ltd., marking one of the first mass-market applications of this technology. While full technical details such as battery capacity and range remain under wraps, expectations are high that semi solid-state batteries could deliver higher energy density, improved safety, and better cold-weather performance compared to existing chemistries.
Solid-state batteries have been a buzzword in the EV industry for over a decade, often described as the “holy grail” of electric vehicle powertrains. Automakers have long promised significant gains in range and charging times, but commercialisation has been slow. With the MG4 Anxin Edition potentially arriving before the end of the year — pricing is expected to be announced in September — consumers may finally see this technology in an affordable, mass-produced EV.
On the outside, the MG4 Anxin Edition retains the same styling as new gen models, including the sharp headlamp clusters, honeycomb-style lower intake, aerodynamic side channels, and a distinctive full-width rear taillight. The dimensions remain identical, with a 4,395 mm length, 1,842 mm width, and a 2,750 mm wheelbase. Inside, the layout features a minimalist two-spoke steering wheel, a floating central touchscreen, and a compact digital driver display.
While it still uses a single-motor, front-wheel-drive setup producing 120 kW, the real talking point is what sits under the floor. If MG can deliver a semi solid-state battery with tangible benefits — without a steep price increase — it could give the MG4 a serious edge in the global EV race. In an increasingly crowded market, technology like this could be the key to transforming the MG4 from an underdog into a segment leader.
