Okay.
The lithium iron phosphate battery is a battery without memory effect and can be charged at any time. It can be charged at any time as needed without harming battery life and performance. After using the battery in the morning, charge it during your lunch break and continue using it in the afternoon without waiting for the battery to be completely discharged. Lithium iron phosphate batteries are very practical and easy to use.
The correct way to charge lithium iron phosphate batteries
It is generally more suitable to charge lithium iron phosphate batteries at 0.5c.
Lithium iron battery, full name is lithium iron phosphate battery, is a type of battery in lithium battery family. Its positive electrode material is mainly lithium iron phosphate material, so. it is also called batrie iron-lithium.
Lithium iron batteries have the advantages of high efficiency, good temperature performance, fast charging and environmental protection. Its performance is particularly suitable for electrical applications, such as large electric vehicles, power tools, small medical equipment and portable instruments.
Lithium iron battery is a type of battery in the lithium battery family. The positive electrode material is mainly lithium iron phosphate material. In 1990, Sony took the initiative to launch a lithium-ion battery using LiCoO2 as the cathode material in the laboratory, and began industrial production in 1991. Compared with traditional lead-acid batteries, lithium-ion batteries have significant advantages in terms of operating voltage, energy density and lifespan. Therefore, lithium batteriesum-ion have been widely used in portable electronic devices, power tools and other fields over the past two decades.In recent years, with the global emphasis on energy saving and emission reduction, lithium-ion batteries have gradually been used in various industries such as communications, national networks and electric vehicles. To save energy and reduce emissions in the communications power sector, batteries need to be smaller, lighter, more durable, more resistant to high temperatures, easier to maintain, more stable in performance and more respectful of the environment.
Therefore, in order to meet these needs, lithium-ion batteries are gradually transforming into large-capacity batteries, and lithium iron phosphate batteries for communicationswe saw the light of day. ABC lithium iron battery is a type of battery in the lithium battery family. The positive electrode material is mainly lithium iron phosphate material.
The correct method for charging lithium iron phosphate batteries: It is recommended to use the CCCV charging method, i.e. first a constant current, then a constant voltage.
It is recommended that the constant current is 0.3 C, the constant voltage is 3.65, or the charging current is 0.3 C during the constant current process. When the battery voltage reaches 3.65V, 3.65. V constant voltage charging is used when charging. Charging stops when the current is less than 0.1C (or 0.05C), that is, the battery is fully charged.
When charging with a constant voltage power supply, the charging current also depends on it. It is recommended not to chargeat too high a voltage. After adjusting the voltage, make sure the charging current is less than 0.5C, which is good for the battery.
Lithium iron phosphate battery general charging upper limit voltage 30.7 ~ 4V, discharge lower limit voltage is 2 ~ 2.5V, comprehensively considering the five aspects of discharge capacity, median discharge voltage, charging time, constant current capacity percentage and safety.
Using constant current and constant voltage charging scheme, for lithium iron phosphate batteries, it is more reasonable to set the charging limit voltage to 3.55~3.70V, the recommended value is 3.60 ~ 3.65 V, and the lower discharge limit voltage is 2.2 V ~ 2.5 V.
Application of ternary lithium batteries< /strong>
In the context of "scope anxiety" and "scope anxiety" in the industry, uLong battery life has become a key focus of the new energy vehicle industry's number one task. There are currently two main technical routes to solve this problem, namely ternary lithium polymer batteries and lithium iron phosphate batteries.
Among them, lithium iron phosphate batteries are the research direction of BYD Auto. At first, they were rarely used due to their low energy density and poor low temperature performance. traditional lithium iron phosphate batteries have been outdated. The density limit reaches the level of ternary materials.
Ternary lithium polymer nickel-cobalt-manganese batteries have a high energy density and are currently the most widely used. However, their cost is high if a breakthrough in security can be made, they will always dominate the market. in the future.
