Chinese entrepreneur Ren Yuanlin, founder of Yangzijiang Shipbuilding Group, is making a major move beyond the shipbuilding industry — acquiring control of the world’s largest supplier of anode materials for lithium batteries.

A consortium of investors led by Ren is purchasing a 23.3% controlling stake in Shanshan Corp for 3.2 billion yuan ($450 million). The deal comes amid a court-supervised restructuring of Shanshan Group, which is facing a debt crisis.

Shanshan Corp holds 21% of the global market for lithium battery anode materials and 30% in display polarization films, making it a critical player in the global battery and electronics supply chain.

The acquisition marks a strategic shift for Ren Yuanlin — from shipbuilding to new energy technologies, as China continues to strengthen its leadership in the renewable energy and advanced materials sectors.

Yangzijiang Shipbuilding Group Ltd., founded in 1956 as Jiangyin Shipbuilding Factory and privatized in 1999 under Ren Yuanlin’s leadership, is China’s largest private shipbuilder. The company specializes in the construction of bulk carriers, container ships, and gas carriers and has been listed on the Singapore Exchange (SGX) since 2007.
