There are a variety of marine battery types. Lead-acid batteries were used first, and then nickel-metal hydride batteries. When lithium batteries appeared, most lead-acid batteries were gradually replaced.
Due to the requirements of environmental protection development, the batteries produced by marine battery manufacturers have basically turned to gold-hydrogen batteries and lithium-ion batteries. Therefore, the current marine batteries mainly include gold hydrogen batteries, energy storage lithium-ion batteries, and lithium iron phosphate batteries. For large ships, due to the wide variety of electronic equipment, they may be installed and used at the same time to meet the actual equipment application requirements. So what’s the difference of these marine batteries?
General energy storage lithium-ion battery
They are generally used for lighting energy storage and emergency lighting. Lithium iron phosphate batteries contain high-temperature resistance, polymer lithium batteries contain low-temperature resistance, gold hydrogen batteries with safe performance, and energy storage lithium-ion batteries with relatively low price, which are widely used at room temperature.
Lithium iron phosphate battery
Lithium iron phosphate batteries perform better than general energy storage lithium-ion batteries. It has high-temperature resistance and high current discharge capacity at a certain rate. The performance is slightly better than that of gold-hydrogen batteries, and slightly worse than that of polymer lithium batteries. In terms of installation costs, lithium iron phosphate batteries are more expensive than hydrogen batteries, and cheaper than polymer lithium batteries. Therefore, most of the currently used marine battery types are lithium iron phosphate batteries, because it is more cost-effective under the same normal temperature application. The production technology is different from the materials used by manufacturers, and the performance effects and cycle life will also be different. Battery manufacturers can design and customize a complete backup power system according to the actual application requirements of marine batteries.
Gold hydrogen battery
The hydrogen battery used on ships is not a common cylindrical battery, but a relatively large hydrogen energy battery system. A set of gold-hydrogen battery equipment is relatively large and heavy, and normally it is impossible to move it after installation. It is mainly used for emergency power conversion of some large electronic equipment that requires a stable power supply. The marine battery system is a relatively complex energy storage system that should be designed and built by relevant electronic engineers. At the same time, the specific use and transportation environment of the ship must be considered to determine the selection and installation of the ship’s battery type.
