Lithium-ion Marine batteries are a high energy density, long life battery technology that has played an important role in electric propulsion ships and other offshore applications. This type of battery has the advantages of lightweight, efficient and environmental protection, and is an excellent substitute for traditional lead-acid batteries and fuel power. With the improvement of environmental protection awareness and the increase of clean energy demand, lithium-ion Marine batteries are more and more widely used in Marine engineering, commercial shipping and recreational vessels.
Lithium-ion Marine batteries are developed based on lithium-ion battery technology, mainly using lithium metal or lithium alloy as negative electrode materials, and various lithium salt compounds as positive electrode materials. During charging and discharging, lithium ions shuttle between the positive and negative electrodes to store and release electrical energy. This battery has several advantages, including:

High energy density: Compared to traditional lead-acid batteries, lithium-ion batteries have a higher energy density, meaning that they can store more energy for the same weight.
