<\/p>\nAccording to CarNewsChina, Dongfeng will start mass-producing its next-generation battery in the second half of this year and immediately start integrating it into vehicles.<\/p>\n
That would make it the first brand to offer solid-state at scale and could open opportunities for Peugeot, with whom the brand has strengthened its ties. But as with many battery promises, the news comes with a caveat.<\/p>\n
The cell from Dongfeng delivers an energy density of 350 Wh\/kg, roughly double that of today’s mainstream lithium iron phosphate (LFP) cells and one-third that of lithium-ion cells. The pack is expected to enable a driving range exceeding 1,000 km while weighing 30% less than a conventional lithium\/ion equivalent.<\/p>\n
Dongfeng officially calls these batteries ‘solid-state’, but \u2013 once again \u2013 semi-solid state is a more accurate description. The battery uses an oxide-polymer composite electrolyte.<\/p>\n
That means the cell is not purely a solid-state device in the way physicists or engineers at Toyota or QuantumScape would use the term. It’s what the industry calls a hybrid construction, blending solid electrolyte material with residual liquid elements.<\/p>\n
This is not a minor definition dispute. China’s industry regulator has been drafting rules to standardize naming, specifically requiring that semi-solid batteries be called ‘solid-liquid batteries’ to prevent public confusion with the fully solid-state variety.<\/p>\n
That distinction matters because the safety and energy density benefits of true all-solid-state chemistry are substantially greater than what oxide\/polymer composites currently deliver.<\/p>\n
The latter are regarded as a stepping stone to the former. In that respect, Dongfeng is following in the footsteps of MG, which has already commercialized its Solid Core semi-solid state pack and will be coming to Europe by the end of the year.<\/p>\n
With that out of the way, the verifiable performance numbers from Dongfeng’s battery remain impressive. In cold-weather testing conducted at winter temperatures of -30\u00b0C, the battery retained over 74% of its charge capacity and delivered a total range of more than 1,000 km.<\/p>\n
That cold-performance figure is a meaningful improvement over conventional lithium\/ion, which typically retains around 60% at the same temperature.<\/p>\n
Safety testing results are equally notable. The cell survived being compressed to half of its original thickness while remaining operational, and passed a 170\u00b0C thermal test without emitting smoke or fire.<\/p>\n
For comparison, China\u2019s national safety standard is 130\u00b0C. The elimination of liquid electrolyte significantly reduces fire risk compared to conventional cells, even if it doesn\u2019t eliminate it (as with solid-state cells).<\/p>\n
The semi-solid-state battery is widely recognized in the industry as the most viable path to rapid mass-market adoption because it is compatible with both existing production equipment and established material supply chains. The fully solid-state battery, with no liquid component at all, remains a different and much harder challenge.<\/p>\n
<\/p>\n
It is illustrated by Dongfeng\u2019s industrial partner Stellantis. The car group announced this week it was starting prototype testing of its Dodge Charger performance EV featuring solid-state battery cells from supplier Factorial.<\/p>\n
This is a genuine, solid-state pack that delivers 90% recharge in just 18 minutes and an energy density of 375 Wh\/kg. Testing is a real-world verification of the lab results. The cells are integrated in an existing battery packaging structure to scale up industrial applications more rapidly.<\/p>\n
Nonetheless, the project is more or less a toe in the water, as no timing was communicated on validation and final production. Only last week, Lotus, which takes a keen interest in true solid-state to comply with its \u2018light is right\u2019 philosophy, claimed mass production is still a decade away. Despite the Chinese race to commercialization, there\u2019s a strong consensus on that deadline.<\/p>\n","protected":false},"excerpt":{"rendered":"
