SAIC has opened pre-orders for the MG 4X, a new electric SUV equipped with semi-solid-state battery technology and priced below $15,000 in China. This positions the MG 4X as a direct competitor to mass-market EVs in one of the world's largest EV markets, where price pressure remains intense.
Semi-solid-state batteries represent an incremental step forward in EV battery chemistry, sitting between conventional lithium-ion cells and fully solid-state designs. They replace the liquid electrolyte with a semi-solid material, improving energy density while maintaining manufacturing compatibility with existing production infrastructure. For consumers, this translates to better range and faster charging compared to current lithium-ion packs, without the technological delays plaguing full solid-state development.
The sub-$15,000 price point proves critical context. Chinese automakers including BYD, Li Auto, and NIO have aggressively pushed downmarket, flooding the segment with affordable EVs that undercut Western competitors on cost. SAIC's MG brand now leverages advanced battery chemistry to defend its position in this crowded space, offering technology differentiation rather than competing purely on price.
The semi-solid-state pack rollout timeline matters for European markets. SAIC plans to introduce this battery technology across its European lineup by end of 2026, targeting markets where buyers prioritize range and reliability. European EV buyers typically accept higher prices than Chinese customers, so the MG 4X's feature set could command a premium there.
This move signals accelerating adoption of next-generation battery tech beyond bleeding-edge premium vehicles. Semi-solid technology serves as a bridge technology, allowing manufacturers to improve performance metrics while avoiding the manufacturing challenges that delayed full solid-state commercialization. Tesla, Ford, and other legacy automakers pursuing full solid-state solutions now face competitive
