MG4 to get world-first semi-solid-state battery, due in Australia in 2026


The first MG4 Anxin Edition electric hatchbacks have been delivered to customers in China ahead of a planned Australian launch in the second quarter (April–June) of 2026.

The MG4 Anxin Edition is the world’s first mass-produced electric vehicle (EV) to use liquid semi-solid-state batteries – a halfway house between current battery technology and solid-state batteries.

The smaller front-wheel-drive MG4, similar in size to the BYD Dolphin, will be sold in Australia alongside an update to the existing rear-wheel- and all-wheel-drive MG4 range.

The MG4 Anxin Edition – with ‘anxin’ translating to ‘relief’ or ‘peace of mind’ – has a claimed 530km CLTC range, equating to 435km (WLTP), and costs ¥102,800 (A$21,944) in China.

It undercuts the BYD Dolphin’s China price of ¥129,800 ($27,707) for the top-spec version – currently in Australian BYD showrooms at $36,990 before on-road costs – which has a claimed 427km (WLTP) range.

It’s not clear if the MG4 will be offered with the liquid solid-state technology here. However, MG Motor Australia has confirmed a 54kWh battery – the same size as the manganese-based lithium-ion liquid solid-state pack in the Anxin Edition – for local showrooms.

MG states the semi-solid-state Anxin Edition has an energy consumption rate of 11.9kWh/100km and can accept 2C ultra-fast charging, allowing it to charge up to 80 per cent in 21 minutes.

Other versions of the front-drive MG4 sold in China use a conventional lithium-ion battery pack. The liquid solid-state battery uses five per cent less liquid electrolyte than conventional versions, improving stability.
