Chinese battery giant CATL plans to file a Hong Kong listing application this week to raise at least US$5 billion (HK$39 billion), according to two sources with direct knowledge of the matter.

The filing could come on Tuesday or Wednesday, added the sources, who could not be identified discussing confidential information.

CATL did not immediately respond to a request for comment from Reuters.

A listing of the Shenzhen-listed firm, the largest battery maker in the world, would be the one of the biggest listings in Hong Kong in the past three years.
