Marine battery is an important part of the ship's power system, which is used to store and provide the electric energy required by the ship. According to different electrochemical principles, structures and uses, marine batteries can be divided into many different categories. This article will introduce the specific classification of marine batteries and the characteristics and applications of various types.

1. Lead-acid battery

lead-acid battery is one of the most widely used marine batteries at present, which is mainly divided into two types: Starting Battery and Power battery.

• Start battery: The engine used to start the ship usually uses lead-acid battery. The starting battery has high starting current and transient power output capability, which is suitable for starting scenarios with short-term high power output.

• Power Battery: it is used to provide power and auxiliary power for ships, usually using deep circulation lead-acid batteries. Power Battery has high cycle life and energy density, which is suitable for long-time power supply and cycle charging and discharging scenarios.

2. Nickel cadmium storage batteries

nickel cadmium storage batteries is a battery with stable performance and long cycle life, which is suitable for ship power systems that are recycled for a long time. Nickel cadmium storage batteries has high cycle life, low self-discharge rate and good high temperature resistance, and is suitable for standby power supply and emergency supply of ships.

3. Ni-MH battery

4. Lithium ion battery

lithium-ion battery is a kind of battery with high energy density and light weight, which is suitable for ships to need light and high-performance power systems. Lithium-ion batteries have the characteristics of high energy density, long cycle life and fast charging, and are suitable for the main power supply and standby power supply of ships.

5. Lead-carbon battery

lead-carbon battery is a kind of battery with high cycle life, low internal resistance and high temperature performance, which is suitable for ship power system requiring high cycle life and high power output. Lead-carbon battery has high cycle life, low internal resistance and high temperature performance, and is suitable for starting batteries and power batteries of ships.

6. Sodium Sulfur Battery

sodium sulfur storage battery is a kind of storage battery with high energy density and long cycle life, which is suitable for ship power system requiring high energy density and long-term power supply. Sodium Sulfur battery has high energy density, long cycle life and high temperature performance, and is suitable for main power supply and standby power supply of ships.

Marine batteries can be divided into many different categories according to different electrochemical principles, structures and uses. Each type of battery has its specific advantages and applicable scenarios. Choosing the appropriate type of marine battery has an important influence on the performance, stability and safety of the ship's power system.
