Groundbreaking EV battery tech coming soon
By Tim Gibson · 13 Mar 2026
Solid-state is often viewed as the holy grail of electric-vehicle battery technology.It promises to offer unprecedented driving ranges, faster charging and a safer overall set-up. Solid-state differs from other more conventional EV batteries because it uses a solid mechanism to transfer energy. Conventional batteries, such as lithium-iron, often contain a gel or liquid electrolyte to do so.It enables far greater energy density than other batteries.With the technology developing and brands edging closer to production, here is a look at some of the latest developments.CheryChery appears to be the brand with the most advanced solid-state strategy, having already announced two models which will feature the technology.The first was announced in December 2025, called the Exeed ES8, with its solid-state battery having a drive range of 1000km. It is scheduled to launch this year in China.More details were recently revealed about Chery’s second model, the Exeed Liefeng, with its Rhino S solid-state battery packing 600Wh per kilogram, bumping up the driving range of 1500km.While the Exeed brand name remains a China-exclusive premium arm of Chery, there is potential for it to make its way to Australia. Chery Australia COO Lucas Harris said he wants to have Exeed models Down Under. “I really like the Exeed product, and I think they make some really cool, really high end, actual luxury specification vehicles,” Harris told CarsGuide. “If I could make a wish tomorrow and it would come true, that would probably be what I would ask for.”BYDBYD is another brand considering solid-state batteries.In early February, it was reported the brand was targeting small-batch production of its batteries by 2027.There are limited other details on BYD’s solid-state battery, with no vehicles confirmed to be installed with it. It is expected it will use an oxide-based chemistry which is viewed as having greater commercial viability than sulphide electrolytes. This is down to easier manufacturing and benefits such as faster and safer charging. FAWFAW (First Auto Works - one of the oldest car manufacturers in China) has taken a different approach to solid-state, with its ‘hybrid’ solid-state battery. This is not to be confused with a traditional internal-combustion and electric-motor set-up. Hybrid refers to the make-up of the battery itself. As mentioned above, most solid-state batteries have a mechanical separator that has liquid qualities.FAW’s battery is different, because the mechanical separator substance is a slurry, meaning it is semi solid-state. The battery has a capacity of 142kWh, with an energy side of 500Wh per kilogram and a driving range of more than 1000km.The brand has installed this battery into a car, but there is no news on potential full-scale production.Mercedes-BenzMercedes-Benz unveiled a prototype solid-state powered version of its EQS sedan in September 2025, which travelled 1205km on a single charge.The car completed a journey from Stuttgart in Germany to Malmo in Sweden without a charging stop, and still had more than 130km of range left when it arrived.Chief Technology Officer Markus Schafer said Mercedes-Benz is targeting production of the battery by 2030. “Our goal is to bring innovations like this into series production by the end of the decade and offer our customers a new level of range and comfort,” Schafer said in a statement.SAICSAIC is another manufacturer targeting a 2027 launch date for its solid-state battery.It has reportedly completed its production line, with sample production beginning late last year.SAIC has stated the battery will have an energy density of 400Wh per kilogram.There is no news yet on whether the battery has been fitted to a car yet or when we might see go into full production.SAIC-owned MG has fitted a semi solid-state battery to its new-generation MG4 in China, but we are unlikely to see it in Australia.ToyotaToyota is aiming to launch a car with a solid-state battery in 2027-2028.The brand has teamed up with mining company Sumitomo Metal Mining to mass produce solid-state battery components.The partnership will produce cathode material needed to make the batteries.Toyota first announced its solid-state plans in 2021, but has not yet produced a prototype.CATLCATL is the world's biggest electric car battery maker, and is expected to have small scale production of its solid-state batteries in 2027.The battery is sulfide-based and its energy density is 500Wh per kilogram.Large scale production is not anticipated until 2030.ConclusionWhile brands, particularly from China, are stepping up their push towards solid-state batteries, it remains a technology in its infancy. There is still substantial opposition to the technology, including from some of the world’s largest automakers such as General Motors (GM). Other battery technologies are also showing promise, which could spell challenges for the development of solid-state.GM has been investigating the potential of silicon alternatives. Silicon graphite blend batteries store more lithium ions to achieve greater battery density, and is rumoured to be closer to commercialisation than solid-state.In addition to BYD's solid-state initiatives, the carmaker recently unveiled its all-electric Denza Z9 GT with 1036km of driving range. It uses a traditional 122kWh lithium-iron-phosphate battery, which might be on its way to Australia.It should be noted that this figure was established using lenient CLTC testing as opposed to more stringent methods such as WLTP.Solid-state remains an exciting future technology in the EV space but, development and production expenses, other battery solutions and technology improvements mean it is still up in the air as to whether we will see it on a commercial scale.
