company news about 2. Types and Selection of Lithium Batteries for Yachts

Yachts are a high-end leisure and entertainment equipment that requires features such as efficiency, safety, environmental protection, and comfort. In order to meet these requirements, the power system of yachts also needs continuous innovation and improvement. At present, lithium batteries, as a new type of energy storage device, have been widely applied and promoted in the field of yachts. So, what are the types and options of lithium batteries for yachts?
According to the different cathode materials of lithium batteries, lithium batteries can be divided into lithium iron phosphate battery, ternary lithium batteries, polymer lithium batteries, soft packed lithium batteries, etc. These lithium batteries each have their own advantages, disadvantages, and applicable scenarios, which need to be selected based on the specific needs of yachts.
Lithium iron phosphate battery is a kind of lithium ion battery with ferric phosphate as cathode material, which has the following characteristics:
Advantages: High safety, less prone to thermal runaway or combustion; Long service life, with a cycle life of over 2000 cycles; Good environmental friendliness, free from heavy metals or harmful substances; The price is relatively low.
Disadvantages: Low energy density, generally between 100~150Wh/kg; The charging and discharging efficiency is relatively low, generally between 85% and 90%; The working temperature range is relatively narrow, usually between -20 ℃ and 60 ℃.
Applicable scenario: lithium iron phosphate battery is applicable to yachts with high requirements on safety, low requirements on endurance mileage and low requirements on charging and discharging speed. For example, small yachts, sightseeing boats, ferries, etc. on inland or offshore rivers.
Ternary lithium battery is a lithium-ion battery with nickel cobalt aluminum or nickel cobalt manganese as the positive electrode material, which has the following characteristics:
Advantages: High energy density, generally between 200~300Wh/kg; High charging and discharging efficiency, generally above 95%; The working temperature range is relatively wide, usually between -30 ℃ and 80 ℃.
Disadvantages: Low safety, prone to thermal runaway or combustion; The service life is relatively short, and the cycle life is generally around 500 times; Poor environmental friendliness, containing heavy metals or harmful substances; The price is relatively high.
Applicable scenario: Ternary lithium batteries are suitable for yachts that require high range, high charging and discharging speed, and low safety requirements. For example, ocean going or large yachts, speedboats, sailboats, etc.
