In recent years, the topic of environmental protection has attracted increasing attention. The types of ship power energy are gradually shifting from fossil energy to low-carbon energy. The trend of electrification is gradually increasing, and it has begun to be vigorously promoted and applied on ships.

Electric ships have the advantages of green environmental protection, zero pollution, safety and low cost of use, and their operating costs are significantly lower than diesel and LNG fuel ships. In addition, electric ships are simple in structure, stable in operation, and low in maintenance costs, making them more suitable for future environmental trends.

Electric ships need to carry a large number of batteries, and have higher requirements for battery discharge rate, cycleability, and cost.

In terms of battery type selection, compared with lead-acid batteries, lithium iron phosphate batteries have obvious advantages in terms of safety, energy density, and cycle performance. However, lithium iron phosphate batteries are currently more widely used in new energy buses and energy storage fields. The lithium iron phosphate batteries used in electric ships will face more technical verifications, require stricter specifications and higher product prices.

Lithium iron phosphate prismatic power batteries with better overall performance in terms of safety, cycle and rate are the mainstream. And as the proportion of lithium iron phosphate batteries used in the field of electric ships increases in the future, the price of products will show a downward trend.

In the future, the trend of ship lithium battery will mainly focus on ferry boats, sightseeing boats, inland cargo ships, port tugboat markets in coastal cities along the river, etc. Some large and medium-sized ships use lithium batteries instead of lead acid, which will accelerate the use of lithium batteries in ships.
