IM Motors says its new L6 model to feature solid-state batteries with over 1,000 km range

The IM L6 will be built on a quasi-900 V high-voltage platform and will be the industry’s first to feature ultra-fast-charging solid-state batteries in a production vehicle, IM Motors co-CEO said.


IM Motors, the electric vehicle (EV) arm of SAIC Motor Corp, will equip its new model, the IM L6, with solid-state batteries that will give the vehicle a range of more than 1,000 kilometers.

The IM L6 will be built on a quasi-900 V high-voltage platform and will be the industry’s first to carry an ultra-fast-charging solid-state battery in a production vehicle, IM Motors co-CEO Liu Tao said on Weibo today.

“Over 1,000 kilometers of range + quasi 900 V ultra-fast charging will completely solve the mileage anxiety of pure electric vehicles,” Liu wrote in Weibo.

Liu emphasized that the more than 1,000-kilometer range will be realized on a four-wheel-drive version, which means a combination of ultra-long range and performance.

Generally speaking, four-wheel drive models offer more performance than two-wheel drive models, but consume more energy.

With exclusive patented technologies such as nanoscale solid-state electrolytes, the solid-state battery will be the industry’s first quasi-900 V ultra-fast-charging solid-state battery, allowing for nearly 1,000 kilometers of range in a shorter period of time, said Liu.

The pack utilizes safer solid-state electrolytes to ensure ultra-high-grade safety of the battery from the cell level, he claimed.

Separately, according to a report by local media outlet Wallstreetcn, the IM L6 will be powered by a solid-state battery with a capacity of 130 kWh.

IM Motors is also planning three generations of solid-state battery products, with specific information to be revealed at the IM L6 technical launch on April 8, according to the report.

In February, the IM L6 made its debut at the Geneva auto show as IM Motors’ fourth model.

The car will be unveiled in China at the 2024 Beijing auto show, which starts in April, and will officially go on sale in China in May, according to information previously announced by the company.

Nio announced the 150-kWh semi-solid-state battery when it unveiled the ET7 sedan at the January 9, 2021 Nio Day 2020 event.

The semisolid battery’s cells come from local startup Beijing WeLion New Energy Technology, which began delivering 360 Wh/kg Li-ion battery cells on June 30, 2023 to the EV maker.

On December 17, 2023, William Li, Nio’s founder, chairman and CEO, drove an ET7 sedan equipped with the 150-kWh battery pack to complete a real-life range challenge.

After 1,044 kilometers of driving, the ET7 had a 3 percent charge remaining and 36 kilometers of CLTC remaining, according to Nio’s announcement at the time.

IM Motors didn’t announce the supplier of its solid-state battery cells, though it appears to be SAIC-backed startup QingTao Energy Development.

On July 6, 2022, SAIC announced that it had formed a joint lab with QingTao to develop solid-state batteries.

On August 30, 2023, SAIC said it plans to form a joint venture with QingTao to build solid-state batteries together.
