The 6C EV battery provides a long range with fast charging. This groundbreaking technology allows drivers to achieve over 124 miles (200 kilometers) of range with just a five-minute charge, helping to reduce range anxiety for electric vehicle drivers.
GM will incorporate the 6C EV battery into its Ultium platform, which powers the company’s next-generation electric vehicles.
The company announced that it plans to integrate the 6C battery into Ultium’s quasi-900V high-voltage battery architecture next year.
Ultium has reportedly served as the foundation for GM’s upcoming electric vehicle models since its introduction in March 2020.
The 6C EV battery incorporates several new technologies aimed at accelerating charging. These advancements enhance the efficiency and reliability of the battery’s chemical reactions.
New Electrolyte Composition
This new battery sets a new benchmark for charging speed, outpacing even the latest models from other EV manufacturers.
The fastest Chinese EV battery currently offers 5.5C, but manufacturers are aiming for even faster solutions.
Li Auto’s first electric vehicle model, the Li Mega MPV, is equipped with a 5C battery developed in partnership with CATL. This is one of the first vehicles to feature such rapid charging capabilities, allowing it to achieve a range of 310 miles (500 kilometers) with just a 12-minute charge.
Zeekr Unveils 2025 Zeekr 007 Sedan as Fastest-Charging EV; Breakthrough in LIB Electrocatalysis Enables 9-Minute Recharge
In August, China’s automobile company Zeekr unveiled the 2025 Zeekr 007 sedan, claiming it as the fastest-charging production car. The model is reportedly equipped with a second-generation Golden Battery that supports a maximum charging multiplier of 5.5C.
The battery pack charges from 10 percent to 80 percent in just 10.5 minutes, providing an additional driving range of 482 kilometers, according to the CLTC test cycle.
In another recent breakthrough, the University of Science and Technology of China developed a novel method for solid-state electrocatalysis in lithium-ion batteries (LIBs). This discovery challenges the traditional understanding of electrocatalysis, which has been limited to interactions at liquid-solid and gas-solid interfaces.
The researchers used a sulfur-doped black phosphorus anode combined with a lithium cobalt oxide cathode in their innovative design. According to Interesting Engineering, this enabled an ultrafast-charging battery that can recharge 80 percent of its energy in just 9 minutes, outperforming previously reported LIBs.
