With the domestic policy requirements for sustainable environmental development, it will become a trend for fishing boats in the fishery to switch from fuel-driven to electric-driven. From the current battery technology, it is most likely that lithium-ion batteries can be used as fishing boat batteries for fishing boats. , So what kind of lithium ion battery is good for fishing boats?
Lithium-ion batteries are classified according to raw materials, including iron phosphate lithium-ion batteries, polymer lithium-ion batteries, and ordinary lithium-ion batteries. According to the battery pack, they are divided into cylindrical steel-case lithium-ion batteries, soft-pack lithium-ion batteries, and square aluminum shells. There are three types of lithium-ion batteries.
1. General ordinary lithium-ion battery
Ordinary lithium-ion batteries are inferior to lithium iron phosphate batteries in terms of high temperature resistance, inferior to polymer lithium-ion batteries in terms of low temperature resistance, and inferior to nickel-hydrogen batteries in terms of safety performance. Therefore, the equipment price is relatively low. Of course, they are generally used for lighting storage. It can be powered and meet emergency lighting. Its placement location is generally a place that can maintain normal temperature. At present, most of the round steel shell lithium-ion batteries are ordinary lithium-ion batteries, and some customized lithium iron phosphate batteries are also available. Cylindrical steel shell lithium-ion batteries are not only limited in shape and capacity, but also in terms of volume and weight. They are not ideal for marine batteries.
2. Polymer lithium ion battery
Polymer lithium-ion batteries are basically in the form of soft-packed lithium-ion batteries, using a laminated production process, so they have a higher degree of freedom in volume, capacity, and shape design. They are small in size, light in weight and capacity. Larger than one-piece lithium-ion batteries are preferred for marine use, but due to their relatively high manufacturing cost and relatively high energy density, the safety performance is relatively difficult to guarantee, so it is difficult to promote and use in the field of fishing boat batteries.
3. Lithium iron phosphate battery
The performance of lithium iron phosphate batteries is better than that of general energy storage lithium ion batteries. It has high temperature resistance and has a large current discharge capacity with a certain rate. The low temperature performance of ordinary lithium iron phosphate batteries is relatively poor, but the improved lithium iron batteries, Slightly better than Ni-MH battery in low temperature performance, slightly worse than polymer lithium ion battery, but high temperature performance will be reduced. In terms of installation cost, lithium iron phosphate batteries are more expensive than nickel-metal hydride batteries and lower than polymer lithium-ion batteries. Therefore, most of the types of ship batteries currently used are lithium iron phosphate batteries, because they are used at the same normal temperature. Next, it is more cost-effective to use iron-lithium-ion batteries.
Lithium iron phosphate batteries have different production technology levels and materials used by manufacturers, and there will be differences in performance effects and cycle life. I want battery manufacturers to produce iron lithium ion batteries for many years. The lithium iron phosphate batteries produced by using a proprietary and patented battery formula include low-temperature iron phosphate lithium ion batteries, high rate iron phosphate lithium ion batteries and conventional iron phosphate lithium ion batteries. , A complete set of backup power system can be designed and customized according to the actual application requirements of marine batteries.
After comparing the advantages and disadvantages of the above-mentioned types of lithium-ion batteries for fishing boats, I believe that many fishing boat owners should understand to choose the appropriate type of lithium-ion batteries according to the operating characteristics of their fishing boats. Generally speaking, lithium iron phosphate batteries are better for fishing boats. Lithium Ion Battery.
