CATL and SAIC-GM have jointly launched a groundbreaking lithium iron phosphate (LFP) battery that offers an unprecedented charging speed of 6C. This remarkable feat allows the battery to be charged for a 200-kilometer range in just 5 minutes, according to a joint statement from the companies.

SAIC-GM, a 50/50 joint venture between China’s SAIC Motor and America’s General Motors, was established in Shanghai in 1997.

This new battery surpasses the previous record held by ZEEKR’s 007 sedan, which featured a 5.5C charging speed. The “C-rate” refers to the speed at which a battery can be charged relative to its capacity. For instance, a 1000mAh battery with a 1C charging rate would take one hour to charge when supplied with a 1000mA current. A 6C charging rate means the same battery would charge in just 10 minutes (1/6 hour) if supplied with a 6000mA current.

Set to be integrated into General Motors’ Ultium quasi-900V architecture in 2025, this battery will benefit from additional design enhancements, including a new CTP structural design and improved cooling technology.

In April, CATL introduced the Shenxing Plus, an LFP battery with an energy density of 205 watt-hours per kilogram. This battery can provide a range of 1000 kilometers on a single charge and boasts a 4C fast-charging capability, enabling it to add around 600 kilometers of range in just ten minutes.

While the energy density of the new battery has not been disclosed, it is likely to be comparable to the Shenxing Plus. However, its standout feature is its significantly higher charging speed.
