What are the benefits of marine lithium batteries?

Ships equipped with diesel power systems, due to their low technical level, produce a large amount of oily wastewater, harmful gases, and particulate matter during navigation and port entry, and suffer from severe noise pollution, which has a serious impact on the aquatic ecological environment. Therefore, electric ships with low energy consumption, zero emissions, low noise, and no pollution have become an important path to achieve energy conservation, emission reduction, and ship system transformation and upgrading, and have received attention from all sectors of society.

In recent years, under the guidance of national policy support and the drive of the new energy vehicle industry, the technological level of lithium-ion power batteries in China has significantly improved, and the cost has significantly decreased. It has a good foundation to support the application and promotion of electric ships. As of now, many cities including Nanjing, Suzhou, Wuhan, Guangzhou, etc. are promoting the electrification replacement of inland ferries, sightseeing boats, cargo ships, and port tugboats, promoting the electrification process of ships.

The same applies overseas. Faced with the increasing pressure of energy conservation and emission reduction in the shipping industry, many ports in countries around the world have implemented strict ship emission standards, forcing ship manufacturing to shift towards electrification. As of now, some overseas regions have even introduced relevant policies to promote the electrification of ships. As stipulated by the Amsterdam City Government in the Netherlands, by 2025, the driving energy of all ships must be converted from diesel to electricity.

In the short term, the Blue Sky Defense War has brought new opportunities for the development of new energy vehicles. But in the long run, the ship electrification and energy storage industries that the country will promote in the future are also starting to take off. However, unlike the development of new energy vehicles, ternary batteries have an absolute advantage in the field of new energy vehicles, while lithium iron phosphate batteries have taken the lead in the field of electric ships.

According to insiders, the most important concern for ship power batteries is high safety, explosion-proof and moisture-proof. It is required that the ship is not affected by dampness and bumps and can still operate normally. Secondly, the cycle life should be advantageous. Typically, the design service life of ships is about 30 years, so there will be relevant requirements for the battery cycle life. From the current situation, lithium iron phosphate batteries with better comprehensive performance in terms of safety, cycling, and rate are more suitable.

Lithium iron phosphate batteries have become the optimal choice for ship power batteries at present due to their high safety, long lifespan, low cost, and balanced performance. Overall, with the increasingly fierce competition in the field of new energy vehicles, more and more battery companies will turn their attention to the field of electric ships and develop targeted lithium battery systems for ships in the future.
