What are the batteries used in electric boats?

The batteries currently used in the electric boat market are generally lead-acid batteries and lithium-ion batteries. Lead-acid batteries are the batteries with the largest market share and the widest range of applications in chemical batteries, especially in applications such as starting and large-scale energy storage, and it is difficult to be replaced by other new batteries for a long time. The price of lead-acid batteries is relatively low, and they have comparative advantages such as mature technology, excellent high and low temperature performance, stability and reliability, high safety, and good resource reutilization. The market has obvious competitive advantages. The shortcomings of lead-acid batteries are low energy density and short cycle life. Lead, an important raw material, is a toxic substance. There is a risk of lead pollution during battery production and regenerated lead processing. Poor management may cause harm to the environment and human health. . As far as lead-acid batteries are concerned, lithium-ion batteries are an extremely outstanding battery. The lithium-ion battery has a high voltage platform, and the uniform voltage of a single battery is 3.7V or 3.2V, which is approximately equal to the series voltage of three nickel-cadmium batteries or nickel-hydrogen batteries, which is convenient to form a battery power pack. Compared with batteries, lithium-ion batteries have high energy density. With high storage energy density, it has reached 460-600Wh/kg, which is about 6-7 times that of lead-acid batteries. Compared with lead-acid batteries, lithium-ion batteries are lighter, and the weight is about 1/5-6 that of lead-acid products under the same volume. The service life of lithium-ion batteries is relatively long, and the service life can reach more than 6 years. The battery with lithium iron phosphate as the positive electrode is charged and discharged with 1CDOD, and there is a record that it can be used 1000 times. With high-power acceptance, the lithium iron phosphate lithium-ion battery used in electric vehicles can reach the charge and discharge capacity of 15-30C, which is convenient for high-intensity start-up acceleration. Low self-discharge rate and no memory effect, it is often used for power supply of daily electronic products. Lithium-ion batteries have strong upper and lower temperature compliance, and can be used in an environment of -20°C to -60°C, and can be used in an environment of -45°C through process disposal. Green and environmental protection, regardless of consumption, use and scrap, no lead, mercury, cadmium and other toxic and harmful heavy metal elements and substances are contained or present. At the same time, lithium-ion batteries are not omnipotent, and they still have certain shortcomings. Lithium-ion batteries have poor safety and risk of explosion. Lithium-ion batteries made of lithium cobalt oxide can't be discharged from large amounts of electricity, and their safety is poor. Lithium-ion batteries need to maintain the circuit to prevent the battery from being overcharged and over-discharged. The consumption requirements are high and the cost is high.
