The long-life battery will have 0 degradation in the first 1,000 cycles, Yutong said.

In addition to the long-life battery, Yutong has also introduced a power battery with a lifespan of 10 years and 1 million kilometers.

Yutong, one of China's largest bus manufacturers, began its first 10-year strategic partnership with CATL in 2012.

On August 9, 2022, CATL and Yutong signed a new 10-year strategic cooperation framework agreement in Zhengzhou, Henan province, where the latter is headquartered.

Yutong's buses equipped with CATL batteries are sold to more than 40 countries and regions, including Qatar, France, the UK and Spain, according to a previous press release at that time.

On March 14, electric vehicle (EV) maker Nio (NYSE: NIO) unveiled its long-life battery strategy in Beijing and signed a deal with CATL to jointly develop long-life batteries.

William Li, Nio's founder, chairman and CEO, said he believes the issue of battery life will gain more attention over the next few years as warranties on previously sold EVs begin to expire.

Over the past few years, China's EV players have addressed issues including battery safety, range, charging efficiency, and cost, but the country's standards haven't improved further when it comes to battery life, Li said on March 17.

He called for more attention to be paid to long-life batteries and for the industry as a whole to work toward that end.

Nio's William Li urges more focus on battery life as warranties expire on nearly 20 million NEVs over next 8 years
