[0002] Ships are important means of water transportation. According to the existing power devices, existing ships can be classified into steam ships, internal combustion ships, steam turbine ships, electric ships and nuclear-powered ships. Electric ships have the advantages of being green, environmentally friendly, zero pollution, safe and low cost. At the same time, due to the simple structure, few rotating parts and reliable operation of electric ships, the maintenance cost is extremely low. Electric ships are in line with the current trend of developing green ships.

[0003] With the development of electric ships, the corresponding market demand for lithium batteries for electric ships has also increased significantly.
