Chinese Electric Car Brand Launches Solid-state Batteries with a Range of 1000 Km

Chinese electric vehicle manufacturer GAC I will will beat some big names in the solid-state battery race.

The company has announced that it will launch all-solid-state batteries (ASSBs) in its Hyper brand of vehicles in 2026, claiming that these large-capacity batteries will provide extremely high energy density and safety.

Solid-state batteries, as the name suggests, use a solid electrolyte rather than a liquid electrolyte found in today’s electric vehicle batteries to stimulate the transfer of electrons.

GAC Aion claims its batteries can offer a range of “easily more than 1000 km” and an energy density of more than 400 Wh/kg.

The company says their volumetric energy density is more than 52 percent higher compared to currently mass-produced liquid lithium-ion batteries.

GAC Aion has subjected its ASSBs to extensive safety testing, including the nail test, where a nail penetrates the battery to ensure it does not burst into flames.

The company states that the batteries have high mechanical strength and temperature resistance as well as non-flammability, which significantly reduces the risk of thermal runaway and improves the membrane’s resistance to damage.

The batteries also feature new silicon anode materials that result in 135 percent improved cycling stability compared to traditional silicon anodes.

The company says they will also be cheaper to produce than traditional lithium-ion batteries.

In future large-scale mass production, equipment investment can be reduced by 15 percent, factory area can be reduced by 40 percent, and manufacturing costs can be reduced by more than 35 percent.

Should it begin mass production in 2026, it will beat Toyota and Nissan, which aim to bring their ASSBs into production by 2027/28.

However, the boss of battery giant CATL recently expressed doubts about the feasibility of solid-state batteries.

“We fully support solid-state, but I have been investing in it for 10 years,” Mr. Zeng said The Financial Timesargues CATL – the world’s largest manufacturer of electric vehicle batteries – is “unmatched” in the race to make this technology viable.

“I watch the development people working on solid-state almost every month, so I know all the progress, and somehow we still have these eye-catchers.”

Mr Zeng said solid-state batteries only had advantages over existing batteries if they used a new type of chemistry along with pure lithium metal for the anode electrode.

He pointed out that there are problems with the diffusion of lithium ions into solid material, and also cited issues with durability and safety.

“[The battery] not many can last [charging] cycles, maybe 10 cycles,” he said, explaining that the expansion of lithium during charging and discharging can damage the battery. “So how do you make it commercially viable?”

He concluded by explaining that solid-state batteries can pose a safety risk because lithium would react with humidity if a battery were to rupture in a car accident.

Some companies have instead opted for semi-solid batteries, which do not have a fully solid electrolyte. SAIC Motor, the parent company of the MG and LDV brands, recently introduced its IM L6 sedan with a 130 kWh semi-solid-state battery that offers a range of over 1000 km on the milder CLTC cycle.

GAC Aion has already announced that it plans to launch in Australia.

Based on our conversations early last year with those familiar with the brand’s plans, a local launch was envisioned in the second half of 2024 and a broader launch in 2025.

It is unclear whether these plans have changed.
