Release Date:2021-03-09 Reading Quantity:1590


Lithium iron phosphate battery has the advantages of high working voltage, high energy density, long cycle life, good safety performance, low self-discharge rate and no memory effect.

I Advantage

Higher energy density
Excellent battery manufacturers can probably achieve the level of 175-180Wh/kg. Some powerful manufacturers use laminated technology and have a larger capacity, or can achieve 185Wh/kg.

Good safety performance
The electrochemical performance of the cathode material of lithium iron phosphate battery is relatively stable, which determines that it has a stable charging and discharging platform. Therefore, the structure of the battery will not change during the charging and discharging process, and it will not burn and explode. It is still very safe under special conditions such as filling, squeezing, and acupuncture.

Long cycle life
The 1C cycle life of lithium iron phosphate batteries generally reaches 2000 times, even more than 3,500 times, and the energy storage market requires 4000-5000 times or more, guaranteeing a service life of 8-10 years, which is more than 1,000 cycles of ternary batteries Life span, while the cycle life of long-life lead-acid batteries is about 300 times.


II  Industrial application of lithium iron phosphate battery

Application of New Energy Automobile Industry
Lithium iron phosphate batteries are widely used in passenger cars, buses, logistics vehicles, low-speed electric vehicles, etc. due to their safety and low cost advantages. Although, in the current new energy passenger vehicle field, it is subject to the state's subsidy policy for new energy vehicles. Influence, relying on the advantages of energy density, ternary batteries occupy a dominant position, but lithium iron phosphate batteries still occupy an irreplaceable advantage in fields such as passenger cars and logistics vehicles.

Start the application on the power supply
In addition to the power lithium battery characteristics, the dynamic lithium iron phosphate battery also has the ability of instantaneous high-power output. The traditional lead-acid battery is replaced by a power lithium battery with an energy of less than one kilowatt-hour, and the traditional starter motor and generator are replaced by a BSG motor. It not only has the function of idle start and stop, but also has the functions of engine stop and coasting, coasting and braking energy recovery, acceleration assist and electric cruise

Energy storage market applications
Lithium iron phosphate battery has a series of unique advantages such as high working voltage, high energy density, long cycle life, low self-discharge rate, no memory effect, and green environmental protection. It also supports stepless expansion and is suitable for large-scale electric energy storage. Energy power stations have good application prospects in such fields as safe grid connection, grid peak shaving, distributed power stations, UPS power supplies, and emergency power systems.

Applications in other fields
Lithium iron phosphate batteries are also widely used in the military field because of their good cycle life, safety, low temperature performance and other advantages.
