Yesterday, China's pioneering pure electric sea passenger ship, 'Yu Jian 77', embarked on its maiden voyage in Xiamen Bay. This vessel is powered by CATL's advanced marine battery system, which innovatively integrates CTP (Cell to Pack) technology and CCS (Cell Contact System) integration technology. Boasting a battery pack energy density exceeding 140Wh/kg, a battery capacity of 3918kWh, and a pure electric range of 100 kilometers, 'Yu Jian 77' is capable of seamlessly operating four round-trips on the Xiamen Bay night cruise route.
